Laparoscopic sleeve gastrectomy (LSG) is used with increasing frequency for the treatment of morbid obesity. The application of robotic techniques has been reported for bariatric operations like laparoscopic Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding, but not for LSG. We report herein our initial experience with LSG performed with the use of the Da Vinci surgical system.

Introduction We present the case of a patient with two tumors in his left kidney and a synchronous colon cancer. While coexisting tumors have been previously described in the same kidney or the kidney and other organs, or the colon and other organs, to the best of our knowledge no such concurrency of three primary tumors has been reported in the literature to date. Case presentation A 72-year-old man of Greek nationality presenting with pain in the right hypochondrium underwent a series of examinations that revealed gallstones, a tumor in the hepatic flexure of the colon and an additional tumor in the upper pole of the left kidney. He was subjected to a right hemicolectomy, left nephrectomy and cholecystectomy, and his postoperative course was uneventful. Histopathology examinations showed a mucinous colon adenocarcinoma, plus two tumors in the left kidney, a papillary renal cell carcinoma and a chromophobe renal cell carcinoma. Conclusion This case underlines the need to routinely scan patients pre-operatively in order to exclude coexisting tumors, especially asymptomatic renal tumors in patients with colorectal cancer, and additionally to screen concurrent tumors genetically in order to detect putative common genetic alterations.

Toll-like receptor 4 (TLR4) has been recently implicated in inflammatory pathways involved in carotid plaque destabilization. Given that statins have plaque stabilization and inflammation reduction effects, we investigated whether TLR4 expression on carotid atherosclerotic plaques correlates with statin intake. Carotid atherosclerotic plaques were obtained on 140 patients (preoperative statin intake, n = 70). TLR4 immunohistochemical expression was investigated in endothelial cells (ECs), macrophages (MACs) and smooth muscle cells (SMCs) of carotid atheroma. TLR4 positivity, over-expression and intensity of immunostaining were compared in statin versus no-statin users. The results of this study showed that statin users had a significantly lower expression of TLR4 in ECs (P = 0.02, 0.001, 0.006 for TLR4 positivity, increased intensity and over-expression, respectively). Similarly, TLR4 positivity was less pronounced in carotid plaque MACs of statin users (P = 0.03). No carotid specimen with increased EC TLR4 intensity or over-expression was observed among statin users. The prevalence of any cerebrovascular accident was 61.4% in the 'no statin' versus 18.6% in the 'statin' group (odds ratio for statin use: 0.14, 95% CI: 0.07-0.31, P < 0.001). In conclusion, statin treatment is associated with attenuated TLR4 expression on human carotid atherosclerotic plaques and a reduced risk of carotid-related cerebrovascular events. TLR4 may potentially mediate statins' plaque stabilization effects. Further investigation is necessary.

BACKGROUND:Laparoscopic Roux-en-Y gastric bypass (RYGBP) for morbid obesity is a challenging operation. The application of robotic techniques has been shown to ease the technical difficulties and reduce perioperative morbidity, mainly because it facilitates the construction of the gastrojejunal anastomosis (GJ). Robotic laparoscopic RYGBP (LRYGBP) has been reported either as totally robotic with manual suturing of the GJ or as robotically assisted with the use of the robot only for the construction of the GJ. A totally robotic LRYGBP with a combined stapled and manual GJ has never been reported.PATIENTS AND METHODS:Nine consecutive patients underwent totally robotic LRYGBP. The GJ was fashioned with a combination of the linear stapler and manual suturing.RESULTS:Mean preoperative body mass index was 45.3 ± 4.7 kg/m(2). In 1 case, we had to undock the Da Vinci Surgical System at the time of the jejunojejunostomy due to unfavorable ergonomics. Mean time to dock the robot was 16.3 ± 3.3 minutes, whereas mean total operative time was 197.2 ± 12.3 minutes. Immediate postoperative morbidity and mortality equaled zero. One patient developed a stenosis of the GJ amenable to endoscopic dilatation. The mean excess weight loss rate 1-year postoperative was 79% ± 15%.CONCLUSION:Totally robotic LRYGBP can duplicate precisely any conventional technique without any compromise in operative time, short- or long-term results.

Implants are widely used and are not without complications. The most serious complication is infection with consequent exposure of the implant and is characterized by increased morbidity and mortality. Until recently, infected implants were removed and replaced with another one. These operations are accompanied by increased morbidity and might result in permanent disability. Coverage of the implant with a flap is an alternative solution. The objective of this article is to study the effectiveness of muscle or myocutaneous flaps in covering infected and exposed implants. A series of 17 patients with infected implants, which were treated with coverage of the implant with muscle or myocutaneous flap, is presented. Eight patients had an orthopedic implant, seven a vascular implant, and two had a pacemaker. The flaps ensured immediate coverage of the implant and the biologic ability of eliminating the infectious process with the increased concentration of antibiotics resulting from increased blood flow of the muscle. In all the patients, the implants were preserved and the infectious process was eliminated. The use of muscle and myocutaneous flaps in the treatment of infected implants is therefore effective and in some cases it is superior to other methods because of lower morbidity and cost.

BACKGROUND:Carcinoid tumors of the extrahepatic biliary tree are extremely rare malignancies, accounting for 0.2%-2% of all gastrointestinal carcinoid tumors, while carcinoids of the cystic duct are an uncommon entity and an extremely unusual cause of bile duct obstruction.METHODS:After an extensive literature review, we retrospectively analysed 61 cases of carcinoid tumor of the biliary tree as well as one additional case of a 60-year-old female with symptoms and laboratory/imaging examination findings compatible with those of a malignant biliary tract obstruction. At laparotomy, resection of the gallbladder and common bile duct was performed. Histological study revealed a well-differentiated neuro-endocrine carcinoma of the cystic duct. The patient remained disease-free at 16 months.RESULTS:Our presentation is the seventh case reported in the world literature. Compared to cholangiocarcinoma, analysis of the reviewed group indicates an increased incidence of extrahepatic carcinoid tumors in younger persons along with a slight female predominance. Statistically, the most common anatomic location is the common bile duct, followed by the perihilar region and the cystic duct. Jaundice is the most common finding. Curative surgery was realized in the majority of cases and long-term disease-free survival was achieved when surgery was curative.CONCLUSIONS:Carcinoid tumors obstructing the biliary tree are extremely difficult to diagnose preoperatively, and nearly impossible to differentiate from non-neuroendocrine tumors. As surgery offers the only potential cure for both biliary carcinoids and cholangiocarcinoma, we recommend aggressive surgical therapy as the treatment of choice in every case of potentially resectable biliary tumor.

BACKGROUND The aim of this study was to assess the prevalence of common ear, nose or throat (ENT) conditions presenting to emergency departments that could be managed by a primary healthcare system Method: Between January 2001 and January 2006 a total of 33 792 patients attended the ENT emergency department of one hospital. All cases were included in this retrospective study. The registry of ENT emergency department was analysed; age, sex and clinical diagnosis were tabulated. All patients were evaluated by a specialist. Classification of the cases was based on the main symptom seeking care. RESULTS A total of 33 792 patients visited the otorhinolaryngology emergency department. Of these, 17 775 patients (52.6%) were men and 16 017 (47.4%) were women. Over 40% of the cases were classified in eight major groups of diagnosis. Acute tonsillitis (12.5%) and acute pharyngitis (11.4%) followed by acute otitis externa (5.9%) were the most common causes of all ENT emergency department visits. The admission rate was 1.2 % and only 0.6% (84) of patients were referred to other specialties. CONCLUSION Most common ENT disorders presenting to the emergency department in Greece could be managed at the level of primary health care. Incorporating ENT expertise into educational and training programmes of general practitioners may be successful in managing ENT problems in primary care in future.

There is no standard treatment for breast cancer patients whose tumors have been exposed both to anthracyclines and taxanes. Oxaliplatin shows synergism with 5-fluorouracil (5-FU) and capecitabine is an oral prodrug of 5-FU with known efficacy in pretreated patients. This phase II trial studied the efficacy and toxicity of the oxaliplatin-capecitabine combination as salvage treatment in breast cancer patients pretreated with anthracyclines and taxanes. Patients received oxaliplatin 80 mg/m(2) on day 1 followed by oral capecitabine 1800 mg/m(2) divided in two doses for 7 days every two weeks for a maximum of twelve courses or until disease progression. Twenty-eight patients were evaluable for efficacy and toxicity. Objective responses (all partial) were documented in 9 patients [32%; 95% confidence interval (CI): 13-51.2%]. Responses were documented at all metastatic sites. The median response duration was 5 months (range 3-9), median time to progression was 4.5 months (range 2-10) and median overall survival was 10 months (range 2-18). Myelotoxicity was minimal with grade 3 thrombocytopenia as the main toxicity. Hand-foot syndrome was well tolerated. The present regimen was well tolerated with a rather moderate effectiveness but very significant for this group of patients. Further studies where the combination could be compared with single agent capecitabine are warranted.

Background: Significant renal artery, stenosis (RAS) in a solitary functioning kidney (SFK) represents one of the most acceptable indications for renal revascularization. Percutaneous transluminal renal artery stenting (PTRAS) is increasingly being used as a first line treatment for renal revascularization, associated with renal function improvement or stabilization in the majority of the patients with solitary kidneys, but also with deterioration in tip to 38% of the cases. Atheroembolism during PTRAS has been postulated as a potential cause for this acute renal function worsening. The aim of this study was to report on the feasibility, safety, and early outcomes of PTRAS in a series of patients with SFK using distal embolic protection (DEP).Methods: All PTRAS procedures in SFKs performed under DEP between June 2002 and September 2007 were reviewed. Renal function, blood pressure, and the number of anti-hypertensive medications were assessed pre- and post-intervention. Renal function improvement and deterioration were defined as a 20% increase and decrease in serum creatinine, respectively compared with preoperative values. Primary and primary assisted patency rates were also calculated. Statistical differences between values before and after intervention were determined by the Student t test and statistical significance was taken at P < .05.Results: Protected PTRAS was performed in 14 patients with a SFK (9 men, 6 women, mean age 65.6 +/- 6.8 years). All patients were hypertensive and had varying degrees of azotemia. Mean pre-intervention stenosis degree was 86.8% +/- 7.8%. Immediate technical success was obtained in 100% of the patients. Renal function was cured (7.1%), improved (50%), or stabilized (42.9%) in all 14 (100%) patients after the procedure and no deterioration was noticed ill any patient at 6-month follow-up. Pre- and postintervention serum creatinine levels were 3.01 +/- 1.15 mg/dL and 2.16 +/- 0.68 mg/dL, respectively, (P = .02). Hypertension was improved in 6 (42.9%) patients and stabilized in the remaining 8 (57.1%). Primary patency was 100% and 90% at 1 and 3 years, respectively, while primary assisted patency remained 100% for the whole follow-up period (mean, 31.8 +/- 19.4 months).Conclusion: These findings suggest that in patients with a SFK, protected PTRAS represents a safe and effective treatment for halting the progression of renal dysfunction to renal loss and warrants further investigation.

Objectives: The current cluster of avian influenza outbreaks in birds has occurred in areas where humans live in proximity to poultry. Dissemination of accurate information may be the cornerstone for proper community preparation. In the herein presented study, we attempted to asses the information level among Greek children regarding avian flu. Methods: A descriptive study was carried out in 2006 in ten Greek prefectures to determine the information level among students about transmission ways, symptoms and prevention measures of avian flu. Results: A total of 1400 Greek students participated in the study. Approximately 75% of the students reported to know what bird flu is and 53% reported to know that there has been at least one case of avian flu in Greece. More than half (55.6%) reported that an effective vaccine against avian flu does exist; of the students asked, 47% reported that avian flu can be transmitted from human to human whereas 21.4% believed that humans can suffer from avian flu. Media contribution in providing information was very high among students. Conclusion: The level of information about avian flu among Greek students was found inadequate especially in some questions regarding serious aspects of avian flu. This study highlights the need for adaptation of health programs in Greek schools, which should include the provision of accurate information.

Background: Oxaliplatin has become one of the major cytotoxic agents for the treatment of gastrointestinal tumors. As a result, several cases of the so-called oxaliplatin-associated hypersensitivity reaction have been documented. Patients and Methods: We have retrospectively evaluated and characterized these reactions in our patient group by reviewing the files of 1,224 patients exposed to an oxaliplatin-containing regimen in order to provide useful clinical information for diagnosis and management. Results: Three hundred and eight (308) patients who have never been exposed to platinum compounds developed symptoms compatible with a reaction to oxaliplatin that was verified by manifestation of at least similar symptoms on rechallenging. The reactions occurred after the first 5 courses, with a median course number of 9 (range 1–24). These reactions could be distinguished as (1) mild reactions occurring in 195 (63%) patients manifesting with itching and small area erythema either during treatment or within the next hours, and (2) severe reactions occurring in 113 (37%) patients within minutes of drug infusion manifesting with diffuse erythroderma, facial swelling, chest tightness, bronchospasm and changes in blood pressure. Oxaliplatin withdrawal was not required in patients with a mild reaction. Forty-eight (42%) patients having a severe reaction with appropriate premedication and prolongation of the infusion duration could tolerate 2–4 subsequent courses. For the remaining 65 (58%) patients, oxaliplatin withdrawal was inevitable because of the very severe reactions occurring on rechallenging. In addition, 3 patients presented with thrombocytopenia and 3 others with hemolytic anemia, all reversible upon oxaliplatin discontinuation. Conclusions: Hypersensitivity reactions to oxaliplatin are underestimated. Although the reactions are not frequent during first courses, in extensively pretreated patients, they may become a serious problem. In the majority of patients, drug discontinuation might not be necessary. In patients manifesting a severe reaction, re-exposure to oxaliplatin should be considered only if the patient can tolerate the reaction and there has been clinical benefit from this therapy. Physicians and nursing staff should be aware of the risk and be well prepared.

A past history of sporadic solid cancers is disclosed in 10% of gastrointestinal stromal tumor (GIST) patients. Simultaneous occurrence with other malignancies is encountered in 14 to 16%, but the synchronous occurrence of GIST and hepatocellular carcinoma (HCC) has been reported only once in the English literature. An 81-year-old male patient is presented with a preoperatively known HCC, in whom a synchronous small nodular omental GIST adjacent to the lesser curvature of the stomach was incidentally discovered. When a GIST is encountered, a thorough intraoperative investigation of the abdominal cavity currently remains the only reliable method for detection of a possible coexisting malignancy.

BACKGROUND:The aim of this study was to evaluate the outcome in patients with liver cirrhosis who underwent laparoscopic cholecystectomy for symptomatic gallstone disease.METHODS:Retrospective analysis of prospectively collected data of 34 patients operated between March 1998 and April 2006.RESULTS:There were 19 male and 15 female patients with a median age of 62 years. Cirrhosis aetiology was viral hepatitis in 25 patients, alcohol in 6, primary biliary cirrhosis in 2 and in 1 patient the cause was not identified. Twenty-three were classified as Child-Pugh-Turcotte stage A and 11 as Child-Pugh-Turcotte stage B. The median Model For End-Stage Liver Disease score was 12. Median operating time was 96 min. In three patients there was conversion to open cholecystectomy. Postoperatively, one patient died and six more patients had complications. Median postoperative stay was 3 days. Patients with acute cholecystitis did not have increased morbidity, but had significantly longer hospital stay.CONCLUSION:Laparoscopic cholecystectomy can be carried out with acceptable morbidity in selected patients with well-compensated Child A and B stages liver cirrhosis. Patients with evidence of significant portal hypertension and severe coagulopathy should avoid surgery.

Purpose: This study evaluated the feasibility, safety, and efficacy of primary stenting in atherosclerotic stenoses and occlusions of the infrarenal aorta.Methods: Between January 2003 and December 2006, 12 patients (6 men) with a mean age of 66.3 +/- 4.1 years who had infrarenal aortic occlusive disease were treated with primary stenting (aortic stenosis, 8; chronic total aortobiiliac occlusion, 4). Reasons for referral were severe claudication in six patients (50%), ischemic rest pain in four (33.3%), and minor tissue loss in two (16.7%). Three patients (25%) had chronic renal failure and were on dialysis. Follow-up was performed in all 12 patients.Results: Technical success was 91.7% because one patient had a residual stenosis >30% after stent placement and balloon postdilation owing to severe calcification of the aorta. However, clinical and immediate hemodynamic success was achieved in all 12 patients (100%). The preprocedural mean resting ankle-brachial index (ABI) values of 0.56 +/- 0.13 at the right side and 0.59 +/- 0.15 at the left were increased to 0.97 +/- 0.04 and 0.95 +/- 0.06, respectively, after treatment (P <.01). At the end of the mean follow-up of 18.3 months (range, 6-37 months), the primary clinical and hemodynamic patency was 91.7% +/- 7.98%, and the mean resting ABI values were 0.96 +/- 0.04 for the right and 0.92 +/- 0.1 for the left side (P <.01 compared with preinterventional values). None of the patients in the study underwent reintervention. An access-related groin hematoma developed in one patient, but no other major or minor complications occurred. One patient died 8 months after the procedure of chronic renal failure complications.Conclusion: Primary stenting is feasible, safe, and effective for the whole spectrum of aortic occlusive disease. Especially for patients with infrarenal aortic stenoses, it is recommended as the first-line treatment and should be considered as a viable alternative to surgery for total aortoiliac occlusions.

OBJECTIVE:The aim of this study was to evaluate the safety and effectiveness of percutaneous cholecystostomy without interval cholecystectomy as definitive treatment for acute cholecystitis in elderly or critically ill patients with various coexisting diseases who were unfit for surgery under general anesthesia.DESIGN:Between July 2004 and June 2006, 24 consecutive elderly and critically ill patients unfit for surgery, suffering from acute cholecystitis, and in whom significant comorbid factors were present, underwent percutaneous cholecystostomy as an emergency procedure at Laiko General Hospital. The diagnosis and the severity of acute cholecystitis were based on the Tokyo Guidelines, whereas the American Society of Anesthesiologists' (ASA) physical status classification was used for the perioperative risk stratification for cholecystectomy.RESULTS:There were 14 male and 10 female patients with a median age of 79 years. Acute cholecystitis was classified as grade 2 in 20 patients and as grade 3 in 4 patients; 17 patients were classified as ASA score III and 7 as ASA score IV, whereas a total of 52 comorbid factors were present. Gallstones were disclosed as the underlying etiology in 23 patients, whereas one patient was diagnosed as suffering from acalculous cholecystitis. Percutaneous cholecystostomy was technically feasible in all patients (100%). Clinical improvement was noticed in 14 patients within 24 hours and in all patients within 72 hours. Statistically significant reduction in the values of white blood cells, C-reactive protein, and axillary body temperature were observed within 72 hours. The procedure-related mortality was 4%, whereas within a median follow-up of 17.5 months, definitive and effective control of symptoms was achieved in 90.5% of the patients.CONCLUSIONS:For the subgroup of extremely high-risk and unfit for surgery patients, percutaneous cholecystostomy might be considered as the definitive treatment since it controls the local symptoms and the systemic inflammatory response.

BACKGROUND:Improving national healthcare services through the enhancement of primary care, is a major challenge in many countries.AIM:To assess the prevalence of those orthopaedic cases that could be managed by a primary healthcare system.METHOD:Between January 2001 and January 2006 a total of 39 172 patients attended the orthopaedic emergency department (ED) of Laikon University Hospital. All cases were included in this retrospective study. The registry of the orthopaedic ED was analysed by age, sex and clinical diagnosis. All patients were evaluated by a specialist. Classification of the cases was based on the main symptom of those seeking care.RESULTS:A total of 39 172 patients visited the orthopaedic ED; 17 040 (43.5%) of these patients were stratified in six major groups of diagnosis. Back pain (17.1%) was the most common reason for seeking care in the orthopaedic ED, followed by ankle injuries (10.3%). The admission rate was 1.2%, and X-ray examination was necessary for 93.4% (15 220) of patients.CONCLUSION:This study confirms the widely held view that most cases attending the orthopaedic ED could have been managed by appropriately equipped primary care settings. In this context, the role of general practitioners should be re-appraised and strengthened.

The successful endovascular repair of a type III thoracoabdominal aortic aneurysm (TAAA) with the use of a tube endograft is reported. A 56-year-old male with a 6.4-cm type III TAAA, a 4.2-cm infrarenal abdominal aortic aneurysm, and chronic renal insufficiency presented with flank pain, nausea, acute anuria, and serum creatinine of 6.1 mg/dl. Acute occlusion of the left solitary renal artery was diagnosed and emergent recanalization with percutaneus transluminal angioplasty and stenting was performed successfully, with reversal of the serum creatinine level at 1.6 mg/dl. Further imaging studies for TAAA management revealed ostial occlusion of both the celiac artery (CA) and the superior mesenteric artery (SMA) but a hypertrophic inferior mesenteric artery (IMA) providing retrograde flow to the aforementioned vessels. This rare anatomic serendipity allowed us to repair the TAAA simply by using a two-component tube endograft without fenestrations (Zenith; William Cook, Bjaeverskov, Denmark) that covered the entire length of the aneurysm, including the CA and SMA origins, since a natural arterial bypass from the IMA to the CA and SMA already existed, affording protection from gastrointestinal ischemic complications. The patient had a fast and uneventful recovery and is currently doing well 6 months after the procedure. To our knowledge, this is the first report in the English literature of successful endovascular repair of a TAAA involving visceral arteries with the simple use of a tube endograft.

BACKGROUND The aim of this study was to evaluate the outcome of laparoscopic cholecystectomy (LC) in octogenarians with complicated gallstone disease. MATERIALS AND METHODS This study was a retrospective analysis of prospectively collected data of 51 patients aged 80 years or older who underwent an LC for complicated gallstone disease between 2001 and 2006. This group was compared with 41 octogenarian patients with uncomplicated gallstone disease. RESULTS There were 51 patients (26 men) with a median (range) age of 87 years (range, 80-93) who underwent an LC for complicated biliary disease, including acute cholecystitis in 29 (57%), gallstone pancreatitis in 14 (27%), cholangitis in 4 (7.8%), and obstructive jaundice in 4 (7.8%). Significantly more patients in the complicated disease group underwent preoperative endoscopic retrograde cholangiopancreatography (33.3% vs. 12.1%; P = 0.026) The median operative time was 110 minutes (range, 55-165) and this was significantly longer, compared to the uncomplicated disease group (P = 0.031). Postoperative morbidity was 27.3%, a significantly higher rate, compared to the uncomplicated group (27.4% vs. 7.3%; P = 0.015) with zero mortality. The conversion rate was 7.8% and this was not significantly different from the uncomplicated disease group. The median length of hospital stay was 6 days, which was significantly longer than the uncomplicated disease group (P = 0.021). CONCLUSIONS The LC can be performed with acceptable morbidity in octogenarians with complicated gallstone disease. Early treatment of gallstone disease in this age group could further improve outcomes.

Background and purpose: Speckle Reduction Imaging is a new algorithm that improves the image quality of B-mode scanning by reducing the reverberation artifacts. In the present study the value of this method for the characterization of atherosclerotic plaques in the internal carotid artery was investigated.Methods: Two hundred and twenty two patients (161 men, 61 women; mean age 73 years) referred for carotid ultrasound evaluation were included in the study. Patients with plaques of the internal carotid artery as identified by conventional B-mode scanning were investigated also with the addition of Speckle Reduction Imaging (SRI) with the use of a 4-11-MHz wide band linear transducer. Plaque morphology was rated according to a standardized protocol by two independent observers.Results: For the determination of plaque echogenicity, the reproducibility of SRI (k = 0.83) was higher than that of conventional B-mode ultrasound (k = 0.68). The interobserver agreement for plaque surface characterization was also higher for SRI (k = 0.8) than for conventional B-mode (k = 0.61). At the evaluation of the image quality through a semiquantitative analysis, SRI was rated superior in the plaque texture resolution, plaque borders determination, vessel wall demarcation and fibrous cap depiction. In addition, the level of "speckle" was reduced with the use of SRI.Conclusions: SRI is a technique that shows good general agreement with high-resolution B-mode and can be used for the characterization of atherosclerotic plaques in the carotid artery. Furthermore, because this advanced technique allows reduction of ultrasound artifacts, it improves the image quality allowing more precise visualization of plaque morphological details.

INTRODUCTIONlatrogenic vascular trauma is more frequent today as a result of the increase in diagnostic and therapeutic femoral catheterizations. Management of related complications is elective or urgent and sometimes needs complex vascular reconstruction. The present study evaluated when and whether conservative, urgent surgical, or elective surgical treatment is appropriate.METHODSA retrospective analysis was made of 45 consecutive iatrogenic vascular trauma patients, among 10,450 cardiac diagnostic or therapeutic catheterizations. Patients' demographics, type of catheterization, time from catheterization to initial diagnosis, the type of complication (thrombosis, infection, bleeding, pseudoaneurysm, etc.), time from presentation of the complication to definite treatment, diagnostic imaging and decision making, the surgical or conservative management, the length of stay and the clinical outcome were determined and analyzed.RESULTSWe identified and treated 30 early and 15 late (after patient's discharge) arterial complications: 18 pseudoaneurysms, 6 bleedings, 9 hematomas, 5 deep vein thromboses, 3 arteriovenous fistulas, 2 arterial embolisms and 2 arterial thromboses. Eight patients underwent emergency surgical repair, three elective surgical repair and 31 were managed conservatively. Decision making was based only on clinical evaluation in 12 patients, whereas vascular ultrasound was the most frequent diagnostic imaging modality in the remainder. A total of 10 (22.2%) minor secondary complications were identified after the initial management with no limb loss and zero mortality.CONCLUSIONSClose clinical observation and conservative management of vascular trauma complications resulted in a low incidence of the necessity for surgical repair (25% of cases). Bleeding and acute leg ischemia were the most frequent indication for emergency surgical treatment, whereas the majority of pseudoaneurysms, fistulas and vein thrombosis were successfully treated conservatively. Late vascular complications do occur and add an important morbidity factor to early catheterization complications.
