This study aimed to assess 5-year effectiveness and safety of femoropopliteal angioplasty with the Luminor® 35 drug-coated balloon (DCB). The EffPac trial was a prospective, multicenter, randomized controlled trial that enrolled 171 patients of Rutherford category 2 to 4 with medium length femoropopliteal lesions. Patients were allocated 1:1 to either Luminor® 35 DCB angioplasty or plain old balloon angioplasty (POBA). Assessment at 5 years included primary patency, freedom from clinically driven target lesion revascularization (CD-TLR), clinical improvement, and target limb amputation. Long-term vital status was ascertained in 97.1
Background Paclitaxel drug-coated balloon (DCB) catheter angioplasty is the preferred treatment for revascularization of femoropopliteal lesions in peripheral artery disease, but mortality is a safety concern. Purpose To assess 2-year efficacy and safety of DCB angioplasty compared with conventional balloon angioplasty (also known as plain old balloon angioplasty or POBA). Materials and Methods This prospective, multicenter, randomized controlled trial enrolled consecutive participants with symptomatic superficial femoral and/or popliteal artery disease at 11 German centers between September 2015 and December 2016. Participants underwent DCB angioplasty or conventional balloon angioplasty. Primary outcome of 6-month late lumen loss showed superiority of DCB angioplasty over conventional balloon angioplasty. Evaluation at 2 years included secondary outcomes of primary patency and target lesion revascularization (TLR) estimated with Kaplan-Meier analysis, clinical and hemodynamic improvement, quality of life, target limb amputation, and all-cause mortality. Results A total of 171 participants (mean age, 69 years ± 8; 111 men) were evaluated. At 2 years, primary patency was achieved in 90.2% (95% confidence interval [CI]: 80.4%, 95.2%) of DCB angioplasty and 62.7% (95% CI: 50.0%, 73.0%) of conventional balloon angioplasty participants (P < .001). Freedom from TLR occurred in 97.2% (95% CI: 89.1%, 99.3%) of DCB angioplasty and 78% (95% CI: 66.5%, 86.0%) of conventional balloon angioplasty participants (P = .001). The groups did not differ in sustained improvement from baseline to 2 years in Rutherford-Becker category (row mean scores difference, 1.7; P = .19) and showed no difference in mean improvement in the Walking Impairment Questionnaire score (-0.8%; 95% CI: -11.8%, 10.2%; P = .88), EuroQol Group's five-dimension index of quality of life (-0.06; 95% CI: -0.17, 0.03; P = .20), or ankle-brachial index (0.03; 95% CI: -0.08, 0.14; P = .57). No major amputation was necessary. One DCB angioplasty and two conventional balloon angioplasty participants died (risk ratio, 0.48; 95% CI: 0.04, 5.10). Conclusion At 2 years after paclitaxel drug-coated balloon (DCB) angioplasty, primary patency and freedom from target lesion revascularization remained superior compared with conventional balloon angioplasty. DCB angioplasty resulted in sustained clinical and hemodynamic improvement with no increased risk of mortality. © RSNA, 2020 Online supplemental material in available for this article.
In their recently published pooled analysis of four drug-coated balloon (DCB) studies, which focused on the impact of patient and lesion characteristics on LLL at 6 months (Albrecht T et al. Cardiovasc Intervent Radiol. 2018 Dec 11. https://doi.org/10.1007/s00270-018-2137-3 ), the authors reported slightly inaccurate 2-year mortality rates.
Background Limited data exist on the impact of prophylaxis on adults with severe hemophilia A and pre-existing joint disease. Objectives To describe 3-year bleeding, joint health and structure, health-related quality-of-life (HRQoL) and other outcomes from the open-label, randomized, multinational SPINART study. Patients/Methods Males aged 12-50 years with severe hemophilia A, 150 factor VIII exposure days, no inhibitors and no prophylaxis for > 12 consecutive months in the past 5 years were randomized to sucrose-formulated recombinant FVIII prophylaxis or on-demand therapy (OD). Data collected included total and joint bleeding events (BEs), joint structure (magnetic resonance imaging [MRI]), joint health (Colorado Adult Joint Assessment Scale [CAJAS]), HRQoL, pain, healthcare resource utilization (HRU), activity, and treatment satisfaction. Results Following 3 years of prophylaxis, adults maintained excellent adherence, with a 94% reduction in BEs despite severe pre-existing arthropathy; 35.7% and 76.2% of prophylaxis participants were bleed-free or had fewer than two BEs per year, respectively. As compared with OD, prophylaxis was associated with improved CAJAS scores (least squares [LS] mean, - 0.31 [n = 42] versus + 0.63 [n = 42]) and HAEMO-QoL-A scores (LS mean, + 3.98 [n = 41] versus - 6.00 [n = 42]), less chronic pain (50% decrease), and approximately two-fold less HRU; activity, Euro QoL-5D-3L (EQ-5D-3L) scores and satisfaction scores also favored prophylaxis. However, MRI score changes were not different for prophylaxis versus OD (LS mean, + 0.79 [n = 41] versus + 0.96 [n = 38]). Conclusions Over a period of 3 years, prophylaxis versus OD in adults with severe hemophilia A and arthropathy led to decreased bleeding, pain, and HRU, better joint health, activity, satisfaction, and HRQoL, but no reduction in structural arthropathy progression, suggesting that pre-existing joint arthropathy may be irreversible.
In several independent randomized clinical studies, it has been shown that drug-coated balloons (DCBs) cause persistent clinically meaningful and statistically significant inhibition of restenosis in femoropopliteal arteries in comparison to percutaneous transluminal angioplasty with uncoated balloon catheters. The potential benefits of delivering an antiproliferative drug into the vessel wall using a balloon as transporter are manifold: 1) widespread applicability: balloon angioplasty is suitable for use in a wide range of lesions. The use of DCBs is technically less demanding and offers greater flexibility compared with stenting techniques. 2) Maintaining options: minimizing the use of durable implants is providing more options for following and complementary revascularization procedures; 3) proven efficacy: consistent, positive outcomes across studies and key subgroups have been demonstrated from the first preclinical studies to ongoing clinical trials. Beside the enthusiasm carried along with this novel technique and questioning if DCBs will become standard-of-care-therapy for the superficial femoral artery, the potential limitations have to be discussed.
Abstract Introduction: The benefits of primary prophylaxis with a factor VIII (FVIII) product in pediatric patients with severe hemophilia A are well established. Fewer data are available on the benefits of secondary prophylaxis (started after ≥2 joint bleeds but before the onset of documented joint disease). The 3-year SPINART study compared the efficacy and safety of routine prophylaxis vs on-demand treatment in adolescents and adults with severe hemophilia A, all of whom were treated with Bayer's sucrose-formulated recombinant FVIII (rFVIII-FS). Primary 3-year data on magnetic resonance imaging (MRI) joint assessments in SPINART have been recently reported. Here we present additional analyses of the SPINART 3-year MRI data. Methods: SPINART was a 3-year, randomized, controlled, parallel-group, open-label study conducted at 31 centers in the United States, Bulgaria, Romania, and Argentina. Male patients aged 12–50 years were eligible for SPINART if they had severe hemophilia A (FVIII:C <1%), ≥150 exposure days to any FVIII product, no current evidence or history of FVIII inhibitors, no prophylaxis for >12 consecutive months in the past 5 years, and 6–24 documented bleeding events or treatments in the previous 6 months. Eligible patients were randomly assigned 1:1 to on-demand treatment or prophylaxis. Patients assigned to prophylaxis received rFVIII-FS 25 IU/kg 3 times weekly; in patients with ≥12 bleeding episodes per year, dose increases of 5 IU/kg were permitted at years 1 and 2. All patients underwent MRI assessments at baseline and year 3 to evaluate the structure of 6 index joints (knees, ankles, elbows). Each MRI was read by 3 radiologists blinded to treatment assignment who independently completed the Extended MRI (eMRI) scale. The eMRI scale has 2 domains (soft tissue, osteochondral), and total eMRI scores range from 0 to 45 based on soft-tissue domain scores of 0 to 9 and osteochondral domain scores of 0 to 36; higher eMRI scores indicate greater joint structural damage. Change from baseline to year 3 in eMRI total score based on all 6 index joints was analyzed for the following baseline characteristics: region (US vs non-US), age (≤29 vs >29 years), and number of bleeding episodes in the previous 6 months (<8 vs ≥8). For patients with target joints, change from baseline to year 3 in eMRI scores in the worst target joint was analyzed using analysis of covariance adjusted for bleeding frequency during the prior 6 months. Results: Eighty-four patients (42 per treatment group) were enrolled in the SPINART study. Target joint analysis data for patients with target joints who completed the study were available for 28 on-demand and 20 prophylaxis patients. Least squares (LS) mean change from baseline to year 3 in eMRI total score in the analyzed target joint was 0.91 (95% CI, –0.06 to 1.88) and 1.09 (95% CI, 0.12–2.07) for the on-demand and prophylaxis groups, respectively; the difference was not statistically significant (LS mean difference, 0.18; 95% CI, –1.05 to 0.70; P=0.68). Results for the subgroup analyses are shown in the Table.

In the prophylaxis group, progression of joint structural damage after 3 years of treatment, as indicated by changes in eMRI total scores based on all 6 index joints, did not differ by number of bleeding episodes in the preceding 6 months but appeared to be less pronounced among younger patients compared with older patients and among those in the non-US group compared with the US group; results by age and region in the on-demand group were opposite of those seen in the prophylaxis group. These results must be interpreted with caution given the small patient numbers, the possibility that the study duration was not sufficient to show changes on MRI, and the fact that target joints were assessed. These results may underscore the importance of preventing target joint development and show that once a target joint has developed, MRI may not show reversal of pre-existing damage despite prophylaxis.

Introduction: In patients with hemophilia, magnetic resonance imaging (MRI) can be used to identify target joints and guide prophylaxis to prevent progressive arthropathy. Current MRI scales developed to assess joint changes, such as the 17-point International Prophylaxis Study Group (IPSG) MRI scale, have limited sensitivity for detecting change in severely damaged joints or for detecting greater joint involvement at lower levels of damage. The Extended MRI (eMRI) scale was developed to provide a means of evaluating the range of joint damage seen in adults with hemophilia. Results from an eMRI validation analysis using baseline data from the 3-year SPINART study, a randomized trial comparing prophylaxis vs on-demand treatment with sucrose-formulated recombinant factor VIII, have been reported. Here, we present eMRI validation results using 3-year data from SPINART.
Background— Peripheral percutaneous transluminal angioplasty is fraught with a substantial risk of restenosis and reintervention. A drug-eluting balloon (DEB) based on a novel coating was compared with uncoated balloons in patients undergoing femoro-popliteal percutaneous transluminal angioplasty. Methods and Results— Patients with symptomatic femoro-popliteal atherosclerotic disease undergoing percutaneous transluminal angioplasty were randomized to paclitaxel-coated IN.PACT Pacific or uncoated Pacific balloons. The primary end point was late lumen loss at 6 months assessed by blinded angiographic corelab quantitative analyses. Secondary end points were binary restenosis and Rutherford class change at 6 months, and target lesion revascularization plus major adverse clinical events (major adverse events=death, target limb amputation, or target lesion revascularization) at 6 and 12 months. Eighty-five patients (91 cases=interventional procedures) were randomized in 3 hospitals (44 to DEB and 47 to uncoated balloons). Average lesion length was 7.0±5.3 and 6.6±5.5cm for DEB and control arm, respectively. Procedural success was obtained in all cases. Six-month quantitative angiography showed that DEB were associated with significantly lower late lumen loss (−0.01mm [95% CI, −0.29; 0.26] versus 0.65mm [0.37; 0.93], P =0.001) and fewer binary restenoses (3 [8.6%] versus 11 [32.4%], P =0.01). This translated into a clinically relevant benefit with significantly fewer major adverse events for DEB versus uncoated balloons up to 12 months (3 [7.1%] versus 15 [34.9%], P <0.01) as well as target lesion revascularizations (3 [7.1%] versus 12 [27.9%], P =0.02). Conclusions— Use of IN.PACT Pacific DEB is associated with significant reductions in late lumen loss and restenoses at 6 months, and reinterventions after femoro-popliteal percutaneous transluminal angioplasty up to 1 year of follow-up.

The development of supra-celiac pseudoaneurysms following aorto-hepatic reconstruction during liver transplantation represents a major and surgically challenging complication. However, the use of endovascular stent grafts for the exclusion of aortic aneurysms is now a standard procedure with low morbidity and mortality. We demonstrate the successful endovascular repair of three cases of supra-celiac pseudoaneurysms, which developed after liver transplantation. A 40-yr-old woman, a 61-yr-old man, and a 45-yr-old woman underwent liver transplantation for end-stage liver disease. Between three months and five yr after the transplantation the patients developed large supra-celiac pseudoaneurysms leading to thrombosis of the hepatic artery and biliary complications. The stent graft implantation was uneventful, one endoleak Type I occluded spontaneously. There were no intervention-related complications. Unfortunately, one patient died one month after the procedure due to progressive liver failure and one died after five months due to multiple organ failure. One patient is still alive and in good condition.
The purpose of the study was to establish a diagnostic approach to the preparation of patients with colorectal liver metastases considered for transarterial radioembolization (RE). Twenty-two patients sequentially underwent computed tomography (CT; thorax/abdomen), magnetic resonance imaging (MRI; liver; hepatocyte-specific contrast), positron emission tomography (PET/PET-CT; F18-fluoro-desoxy-glucose), and angiography with perfusion scintigraphy [planar imaging; tomography with integrated CT (SPECT-CT)]. The algorithm was continued when no contraindication or alternative treatment option was found. The impact of each test on the therapy decision and RE management was recorded. Patient evaluation using CT revealed contraindications for RE in 4/22 patients (18%). Of the remaining 18 patients, 2 were excluded and 3 were assigned to locally ablative treatment based on MRI and PET results (28%). The remaining 13 patients entered the planning algorithm: SPECT-CT revealed gastrointestinal tracer accumulations in 4 (31%) patients [SPECT, 2 (15%)], making a modified application necessary. In five patients (38%), planar scintigraphy revealed relevant hepatopulmonary shunting. Therapy was finally administered to all 13 patients without therapy-related pulmonary or gastrointestinal morbidity. Each part of the diagnostic algorithm showed a relevant impact on patient management. The sequential approach appears to be suitable and keeps the number of unnecessary treatments and therapy risks to a minimum.
To assess both sensitivity and specificity of digital chest radiography alone and in conjunction with dual-exposure dual-energy chest radiography for the detection and classification of pulmonary nodules. One hundred patients with a total of 149 lung nodules (3-45 mm; median, 11 mm) confirmed by CT were included in this study. Dual-exposure dual-energy chest radiographies of each patient were obtained using a CsI detector system. Experienced board-certified chest radiologists from four different medical centers in Europe reviewed standard chest radiographs alone and in conjunction with dual-energy images blinded and in random order. The reviewers rated the probability of presence, calcification and malignancy of all lung nodules on a five-point rating scale. Lesions detected were identified by applying a specific coordinate system to enable precise verification by the study leader. A receiver-operating characteristic (ROC) analysis was performed. In addition to the 149 true-positive CT proven lesions, 236 false-positive lung nodules were described in digital chest radiographies in conjunction with dual-energy chest radiographies. The cumulative sensitivity of chest radiography in conjunction with dual energy was 43%, specificity was 55%. For digital radiography alone, sensitivity was 35% and specifity was 83%. For the dual energy system, positive predictive value was 58%, and negative predictive value was 66% compared to the digital radiography with a positive predictive value of 59% and a negative predictive value of 65%. Areas under the curve in a ROC analysis resulted in 0.631 (95% confidence interval =0.61 to 0.65) for radiography with dual energy and 0.602 (95% confidence interval =0.58 to 0.63) for digital radiography alone. This difference was not statistically significant. For the detection of lesion calcification or the determination of malignancy, ROC analysis also failed to show significant differences. CsI-based flat-panel dual-exposure dual-energy imaging added to standard chest radiography did not show statistically significant improvement for the detection of pulmonary nodules, nor the identification of calcifications, nor the determination of malignancy.
Background and objective Traditionally, large lumen, tunneled central venous catheters have been implanted by surgeons. We used a technique of sonographically guided jugular venous puncture and fluoroscopically guided catheter placement to achieve a high rate of technical success and to reduce complication rates. Materials and methods Between June 2002 and December 2006, 186 Patients have been referred to the Radiology Department for 211 implantations of large-lumen, tunneled, central venous catheters. Insertions were performed under maximum sterile barrier in the angio suite using combined sonographic guidance for puncture of the internal jugular vein and fluoroscopy for placement of a triple lumen 12.5 F catheter (Hickman, BARD Murray Hill, NJ, USA). All interventions were performed under local anesthesia without need for anesthesiologic surveillance. Peri- and postinterventional complications were recorded using standardized international recommendations. Results Catheter implantation was technically successful in 207 of 211 cases (98.1%). Technical failure resulted in four patients due to chronic occlusions of the superior vena cava. No major complications were recorded. Four (1.9%) accidental arterial punctures occurred periinterventionally; 24 (11.4%) early complications (bleeding, dysfunction, catheter rupture, and infection) and ten (4.7%) late complications (infection, dysfunction) were recorded. A clinically suspected catheter infection required catheter removal in 21 (10%) cases; 11 of 13 non-infectious catheter complications (bleeding, dysfunction, rupture) could be treated successfully by interventional-radiological treatment. Conclusion Percutaneous implantation of large-lumen, tunneled, central venous catheters can be achieved with a high technical success rate and a low complication rate under combined sonographic and fluoroscopic guidance. In cases of mechanical complications, catheter rescue by interventional techniques is possible in the vast majority of cases.
Background - The success of percutaneous intervention in peripheral arterial disease is limited by restenosis. The aim of the present pilot study was to evaluate a novel method of local drug delivery.Methods and Results - This randomized multicenter study with blinded reading enrolled 87 patients in Rutherford class 1 to 4 with occlusion or hemodynamically relevant stenosis, restenosis, or in-stent restenosis of femoropopliteal arteries. Treatment was performed by either conventional uncoated or paclitaxel-coated balloon catheters. The primary end point was late lumen loss at 6 months. Secondary end points included restenosis rate, ankle brachial index, Rutherford class, target lesion revascularization, and tolerance up to > 18 months. Before intervention, there were no significant differences in lesion characteristics such as reference diameter (5.3 +/- 1.1 versus 5.2 +/- 1.0 mm), degree of stenosis (84 +/- 11% versus 84 +/- 16%), proportion of restenotic lesions (36% versus 33%), and mean lesion length (5.7 cm [0.8 to 22.6 cm] versus 6.1 cm [0.9 to 19.3 cm]) between treatment groups. The 6-month follow-up angiography performed in 31 of 45 and 34 of 42 patients showed less late lumen loss in the coated balloon group (0.5 +/- 1.1 versus 1.0 +/- 1.1 mm; P = 0.031). The number of target lesion revascularizations was lower in the paclitaxel-coated balloon group than in control subjects (3 of 45 versus 14 of 42 patients; P = 0.002). Improvement in Rutherford class was greater in the coated balloon group (P = 0.045), whereas the improvement in ankle brachial index was not different. The difference in target lesion revascularizations between treatment groups was maintained up to > 18 months. No adverse events were assessed as related to balloon coating.Conclusions - In this pilot trial, paclitaxel balloon coating caused no obvious adverse events and reduced restenosis in patients undergoing angioplasty of femoropopliteal arteries.
The purpose of the study is to evaluate radiological–interventional central venous port catheter corrections in migrated/malpositioned catheter tips. Thirty patients with migrated/malpositioned port catheter tips were included in this retrospective analysis. To visualize the catheter patency, a contrast-enhanced port catheter series was performed, followed by transfemoral port catheter correction with various 5F angiographic catheters (pigtail, Sos Omni), goose-neck snare, or combinations thereof. One patient showed spontaneous reposition of the catheter tip. In 27 of 29 patients (93%), radiological–interventional port catheter correction was successful. In two patients, port catheter malposition correction was not possible because of the inability to catch either the catheter tip or the catheter in its course, possibly due to fibrin sheath formation with attachment of the catheter to the vessel wall. No disconnection or port catheter dysfunction was observed after correction. In migrated catheter tips, radiological–interventional port catheter correction is a minimally invasive alternative to port extraction and reimplantation. In patients with a fibrin sheath and/or thrombosis, port catheter correction is often more challenging.
To evaluate the feasibility and safety of minimally invasive, percutaneous techniques in metachronous recurrent renal cell cancers (RCCs) in solitary kidneys.
