The formation of a comprehensive program includes medical, professional and sociopsychological aspects and contributes to early recovery.

Introduction. The number of victims with abdominal trauma over the past 20 years has not tended to decrease due to an increase in the number of road accidents, falls from heights, man-made disasters and natural disasters. Diagnosis of damage to hollow organs should be fast and accurate, since the time factor in providing medical care to such patients is crucial. The delay of surgery for intestinal injury for 24 hours or more is associated with an increase in the mortality rate of up to 30%. In such cases, computed tomography is the method of choice for hemodynamically stable patients with closed abdominal trauma.The aim is to demonstrate the possibilities of computed tomography in the early detection of damage to the small intestine and mesentery using the example of a clinical case of closed combined abdominal trauma with damage to a hollow organ and multiple injuries of the musculoskeletal system.Materials and methods. A clinical case of combined trauma of a patient in a traffic accident is described.Conclusion. In this clinical case, the victim with a combined injury was shown the modern possibilities of computed tomography in early detection of damage to the walls of the small intestine and mesentery, which made it possible to make a timely decision on emergency surgery, avoid serious complications, restore the patient's ability to work and quality of life.

Using the example of clinical observation, the features of withdrawal from shock, the possibility of using hemofiltration in the early stages after severe combined trauma complicated by blood loss to soft tissues, which made it possible to avoid the development of infectious complications, are shown.

Relevance. Liver trauma is one of the most common abdominal injuries. The purpose is to review the evidence and present the current level of diagnosis, tactics and treatment of blunt liver trauma.Materials and methods. The results of clinical studies in liver trauma have been analyzed. Literature was searched in PubMed electronic search engines (https://pubmed.ncbi.nlm.nih.gov), eLibrary (https://elibrary.ru) by keywords: "liver trauma", "management liver trauma", "diagnosis liver trauma". 134 publications were selected for analysis.Results. Historically, most patients with liver trauma were cured promptly using techniques such as liver suturing, liver resection, ligation of the hepatic artery, atrioval shunts. Conservative management was practically not used. Consequently, mortality was high and reached almost 90% in patients with severe trauma, including damage to the main hepatic vessels. The introduction of such techniques as perigepathic packaging and direct suturing of damaged vessels significantly improved the prognosis of patients. The widespread use of conservative therapy in patients with stable hemodynamics, the management of which is based on instrumental assessment, carefully selected diagnostic imaging of the nature of liver injury, instrumental dynamic observation using operative X-ray angiology and endoscopy, in a hybrid operating room, contributed to the improvement of treatment results.Conclusion. In recent decades, conservative therapy has been performed in 80–86% of cases in patients with stable hemodynamics. The use of minimally invasive interventions such as angiography and embolization, a combination of percutaneous drainage and endoscopic methods for injury to vascular and biliary structures can be considered as the main method of treating post-traumatic complications.

The objective was to evaluate the effectiveness and safety of video-assisted thoracoscopic surgery for closed chest trauma and to determine the most favorable terms for performing surgical intervention in case of complicated closed chest injury. METHODS AND MATERIALS. The study included 95 patients who underwent video-assisted thoracoscopy (VATS) for closed chest trauma. Group I – operated within the first 5 days from the moment of injury; group II – operated within 5–10 days after injury; group III – operated later than 10 days after injury. RESULTS. Performing thoracoscopic intervention within the first 5 days after the injury significantly reduces the incidence of complications such as pneumonia, pleurisy, empyema. VTS allows safely and effectively performing various surgical procedures in case of complicated closed chest trauma, and diagnosing diaphragm injuries. CONCLUSION. Indications for video-assisted thoracoscopy should be set as early as possible.

BACKGROUND Acute proximal aortic dissection (Stanford type A) remains the most common fatal pathology of the thoracic aorta. Despite the improvement of surgical technologies, hospital mortality after emergency surgical interventions is 17–25%, in complicated cases it can reach 80–90%. AIM OF STUDY Description of the perioperative treatment tactics adopted at the N.V. Sklifosovsky Research Institute for Emergency Medicine as well as the evolution of approaches that make it possible to obtain satisfactory hospital and long-term results in the treatment of aortic dissection. MATERIAL AND METHODS the study included 278 patients operated on from 2015 to 2021 in the acute stage of aortic dissection (less than 48 hours from the moment of manifestation of the disease). The operated patients were divided into two groups, depending on the presence of complicated forms: group A, 102 patients with uncomplicated course of the disease; group B, 176 patients with complicated course of the disease. Additionally, patients were divided depending on the level of distal reconstruction performed: group I, 83 patients, surgery was limited to prosthetics of the ascending aorta, without removing the clamp; group II, 137 patients who underwent hemi-arch surgery; group III, 58 patients, with distal reconstruction involving the aortic arch. RESULTS Total hospital mortality was 28.1%: 25.3% in group I, 29.1% in group II, 29.3% in group III. In the group of uncomplicated dissection, postoperative mortality was 18.6%, while in the group of complicated dissection it was 33.5%. CONCLUSION An integrated multidisciplinary approach with the formation of an “aortic team”, an individual approach to surgery, depending on the anatomy of the dissection and the clinical status of the patient, will improve the results of the treatment of acute aortic dissection, as the most severe and multiple organ pathology of the aorta. FINDING 1. Hospital mortality of complicated forms of dissection remains significantly higher — 33.5% versus 18.5% of uncomplicated course. 2. The most optimal method of distal reconstruction in patients with the peracute stage of dissection is an open anastomosis with the aorta using the “hemi-arch” technique. 3. If it is necessary to extend the surgical intervention on the aortic arch, a distal anastomosis in areas 0, 1, 2 with the possibility of a subsequent endovascular stage is the priority.

The purpose of the study. To study the possibilities of computed tomography (CT) in the diagnosis of spontaneous hematoma of the esophagus, including in the process of dynamic observation. Materials and methods. A retrospective analysis of CT results in 11 patients with spontaneous esophageal hematoma treated at the N.V. Sklifosovsky Research Institute of SP in the period 2005–2020 is presented. All patients underwent a comprehensive laboratory and instrumental examination, including CT. CT studies were performed with oral and intravenous bolus contrast, primarily at admission and in dynamics. Results. In all cases, according to CT data, acute pathology of the aorta, rupture of the esophagus were excluded and signs of spontaneous hematoma of the esophagus were revealed. CT semiotics of esophageal hematoma was analyzed with quantitative treatment of changes in density, linear dimensions and volume. CT semiotics analysis also revealed the volumetric effect of hematoma on surrounding organs and structures, accumulation of blood in the pleural cavities, and verified signs of infection of hematoma with inflammatory changes in the surrounding paraesophageal tissue. CT data served as the basis for determining the optimal treatment tactics for spontaneous esophageal hematoma. Conservative therapy was the main method of her treatment. CT examination in dynamics allowed timely detection of complications of spontaneous hematoma of the esophagus (hemothorax, perforation of the esophagus, infection of the hematoma) requiring surgical intervention. Conclusion. CT is the method of choice in the diagnosis of spontaneous hematoma of the esophagus, which allows for a clear differential diagnosis with urgent life-threatening conditions. CT data make it possible to justify treatment tactics and assess the dynamics of the pathological process.

Relevance . Modern methods of diagnosis and treatment of victims with severe combined trauma, the fulfillment of the conditions of the "golden hour" do not solve the problem of a favorable outcome, sepsis and multiple organ failure (PON) remain the main cause of death. The purpose of the study . To study the possibilities of complex diagnostics and treatment using combined methods of extracorporeal hemocorrection in patients with PON after severe combined breast injury. Object and methods . The results of diagnosis and treatment of 20 victims with combined chest injury were analyzed. The criteria for inclusion in the study were as follows: age over 18 years; severe combined closed chest injury: AIS > 2 on the background of combined injuries, ISS 28–34 points, severity of the condition on the ARASNE II scale over 20 points, the use of extracorporeal hemocorrection (MEG) methods. The results of the study. In patients with severe combined breast injury, the severity of the course of multiple organ failure is shown and the effectiveness of combined methods of extracorporeal hemocorrection (MEG), the features of manifestations of PON and the dynamics of changes in indicators against the background of complex treatment is determined. The main method of diagnosis of PON was a clinical and laboratory picture, taking into account coagulological, biochemical disorders, biomarkers of inflammation and instrumental assessment of CT of the lungs and ultrasound picture of the state of parenchymal organs of the chest and abdomen. С onclusions . An integrated approach to the management of victims with PON, including early MEG, helps to reduce intoxication, stabilize the condition and increases life expectancy.

On the example of a clinical observation, we demonstrate the possibilities of dynamic multimodality imaging techniques and clinical and laboratory data, taking into account the severity of the concomitant trauma, which allow us to reflect objectively the dynamics of post-traumatic changes in the organs and tissues and predict the course of multiple organ failure (MOF). Consistency and adequate choice of treatment tactics with early use of active detoxification methods contribute to a favorable outcome.

Relevance. Spontaneous hematomas (SG) appear after 2–3 weeks from the start of treatment for COVID infection and are observed mainly in elderly people with concomitant pathology. The predisposing factors for the development of SG in patients with COVID-19 are coagulopathies. The mortality rate in SG is 04–30 %, while in patients with COVID infection in severe cases increases to 30–50 %. The purpose of the study. To determine the role of coagulological changes in the development of soft tissue SG and to identify the features of the course, taking into account localization in patients with COVID infection. Materials and methods. The results of diagnosis and treatment of 54 patients with spontaneous hematomas were analyzed. The average age was 68.5 years (38–93), there were 45 women (83.3 %), 9 men (16.7 %). Lung damage by CT in most patients was severe. Anticoagulant and antiplatelet therapy was prescribed to all patients from the moment of admission. The management tactics of patients was carried out on the basis of a comprehensive instrumental assessment. Results. SG was mainly observed in retroperitoneal tissue (28) of patients, chest wall (14), rectus abdominis muscle (6), combination of hematoma of preperitoneal and retroperitoneal tissue (3), other localization of neck, hip, mediastinum (3). The volume of SG ranged from 60 to 2850 cm 3 . Unfractionated heparin was used as anticoagulant therapy. All patients had a statistically significant decrease in the level of hemoglobin and erythrocytes relative to the norm during all study periods (p < 0.05). The number of platelets decreased statistically significantly in the group with SG with localization in retroperitoneal tissue and in the chest (p < 0.05). The level of PH at admission was reduced in patients with SG with localization in retroperitoneal tissue and in the chest relative to the norm (p<0.05). The value of D-dimer was statistically significantly increased relative to the norm during all study periods in all groups. The treatment was aimed at correcting hemostasis, hemotransfusion with a decrease in hemoglobin levels below 60 g/l, plasma transfusion and thromboconcentrate. Conclusions. The severity of patients with SSG of various localization is due not only to the volume of SG against the background of COVID infection, but also to a variety of concomitant diseases, features of localization, volume and nature of SG. In patients who initially have deviations in the indicators of the hemostasis system, the risk of OHSS is higher, they need to more carefully select the optimal doses and the course of thromboprophylaxis. Early diagnosis using ultrasound, CT, X-ray endovascular hemostasis against the background of hemostatic therapy contributes to the stabilization of the condition and a favorable outcome.

The study was conducted in the Thoracoabdominal Department of the N.V. Sklifosovsky Research Institute for Emergency Medicine to explore the role of paravertebral block in the treatment of blunt chest trauma. The study included 715 patients with isolated chest trauma hospitalized between January 1, 2020 and August 2021. 55 patients received analgesic therapy in the form of paravertebral block. The comparison group included 660 patients who did not undergo paravertebral block, in their case pain relief was provided by systemic administration of analgesics. The compared groups did not differ significantly in sex and age composition. There were also no differences in the frequency of chronic diseases and interpleural complications. There were no significant complications during the block. The comparison revealed a significant decrease in the incidence of pleurisy and a shorter length of stay in hospital. Paravertebral block is an effective and safe method of pain management for patients with blunt chest trauma. The use of this technique reduces the incidence of post-traumatic pleurisy and duration of hospitalization.

The purpose of the study. To clarify the possibilities of using radiation research methods in the framework of complex diagnostics of local peritonitis for timely recognition and treatment of intra-abdominal abscesses and infiltrates.Materials and methods. The analysis of the results of a complex radiation examination in 61 patients with local peritonitis of various etiologies who were treated at the N.V. Sklifosovsky Research Institute for Emergency Medicine was carried out. The complex of radiation diagnostics included ultrasound and X-ray examinations, computed tomography (CT). The studies were performed both initially at admission and in dynamics.Results. The diagnostic algorithm for local peritonitis is analyzed, three stages are identified with the determination of the method of choice on each of them. Ultrasound and X-ray examination methods are mainly used at the stage of primary diagnostics and for dynamic control. CT allows you to clarify the type, localization and volume of inflammatory changes, their relationship with the surrounding organs and structures. When analyzing the results of radiation diagnostics, it was determined the need to identify and evaluate the main signs of local peritonitis, both direct: the presence of voluminous formation of inflammatory genesis (infiltrate and/or abscess); and indirect: changes in the source organ of peritonitis; changes in structures adjacent to the infiltrate /abscess; the presence of reactive effusion into the thoracic and abdominal cavities.Conclusion. Comprehensive radiation diagnostics for local peritonitis makes it possible to obtain complete information about the nature of both inflammatory changes in local peritonitis and the causes of them. The obtained data of complex diagnostics help the surgeon to choose a rational treatment strategy for these patients, including minimally invasive. Diagnostic monitoring allows you to evaluate the effectiveness of treatment and carry out timely correction of tactics.

The aim of study Based on computed tomography data, to determine the most characteristic criteria for true lumen (TL) and false lumen (FL) in aortic dissection. To identify the relationship of the studied features with the stage of aortic dissection. Materials of the study Computed tomography (CT) data of 115 patients diagnosed with aortic dissection (AD) who were treated at the N.V. Sklifosovsky Research Institute for Emergency Medicine were analyzed. The average age of the patients was 54.5 years (median — 56 years), men predominated in the studied group. AD types according to the De Bakey classification were distributed as follows: Type I — in 47% of patients, Type II — in 16.5%, Type III — in 36.5%. Dissection in the acute stage occurred in 62% of the patient, in the subacute — in 16%, in the chronic — 22%. Results In the studied group, FL in all cases prevailed over the TL by size, regardless of the stage and type of AD. Analysis of lumen ratio showed that in 63.55% of patients, FL occupied 75% or more of the aortic cross-sectional area. Location of FL: at the level of the ascending aorta, along the right and anterior walls of the aorta — 94.5%; in the descending thoracic aorta, along the posterior and left walls — 84%; in the abdominal aorta, along the posterior and left walls — 70%. Calcifications of the non- dissected part of the aortic wall, as a sign of a true lumen, were found in 59.1%. There was no correlation between calcification and the AD stage. Partial thrombosis of one of the lumens was detected in 59% (in FL — 85%, in TL — 13%, thrombosis of both lumens — 2%). The beak signs occurred in 85% of patients with AD, however, it was significantly more often detected in patients with acute and subacute AD stages than in the chronic stage (p<0.001). The cobweb sign was found in one third of patients with AD, however, it was statistically significantly more often determined in patients in acute and subacute stages (p<0.05). Conclusion CT is reasonably considered a highly informative method of diagnosing AD. The signs of true and false lumen presented in the work, as well as their combination, make it possible to perform a quick and error-free marking of the aortic lumen with a high degree of probability. A number of the described CT signs correlate with the stage of AD.

On the example of a clinical case, the possibilities of radiation diagnosis of a rare type of injury received from a construction and installation gun are shown. The modern possibilities of radiation diagnostics in the detection of injuries and complications in a gunshot wound of the chest are shown. Ultrasound data on the presence of intrapleural contents allowed us to determine the penetrating nature of the wound. The data obtained by polypositional chest radiography gave an idea of the localization and size of the foreign body. During chest CT, an accurate anatomical characteristic of the wound canal was given, the exact localization of the foreign body was indicated, an intrapulmonary hematoma, a lung contusion were identified, the exact nature and volume of the intrapleural contents were determined. In the postoperative period, CT revealed PE and infarct pneumonia, and scintigraphy assessed the total deficit of lung perfusion, which affected the treatment tactics. In the diagnosis of complications of breast injury such as intrapulmonary hematoma, infarction pneumonia, inflammatory changes in the soft tissues of the chest wall, ultrasound diagnostic data are comparable with CT results.

The possibilities of computed tomography in the diagnosis of spontaneous hematomas (sh) of the soft tissues of the neck and chest and the features of their treatment are shown. Computed tomography with intravenous bolus contrast enhancement is the main method for diagnosing sh, which allows you to specify its exact localization, distribution, determine the structure and volume of the hematoma, the contrast agent exiting the contours of the vessel, and, taking into account the data obtained and the clinic, determines the tactics of treatment.Stable sh does not require surgical treatment. In the case of a large volume of chest hematoma, compression syndrome, hemothorax, drainage is indicated. Unstable sh dictate the need for angiography and, if necessary, endovascular embolization.

Despite the existing progress in providing care to patients with severe multisystem chest injury using advanced diagnostic methods, a high mortality rate still reaches 20–30%.Aim of study.To assess the impact of early diagnosis and correction of chest injuries on the development of complications in patients with multisystem trauma.Material and methods.The results of diagnosis and treatment of 89 patients with severe multisystem closed chest injury were studied. According to the time of admission to the Institute, the patients were divided into two groups: Group I, who were admitted to the Institute within the first hours after the injury (51 patients), and Group II, who were transferred from other medical institutions on the 3rd–7th day (38). CT was performed as a standard method of diagnosis and monitoring the dynamics of the process. With the development of purulent-inflammatory pulmonary complications, the bacteriological test of bronchoalveolar lavage was performed. Treatment included complex intensive therapy, drainage of the pleural cavity and emergency surgical interventions, if necessary.Results.In Group I, lung contusion occurred in 43 (84%) patients, and after 7-10 days, the contusion foci partially regressed in 20 (46.5%) patients. In 8 (16%) patients with lung rupture, infiltrative changes in the lung were resolved on the 18th-30th day, while 4 (50%) of them had pneumonia outside the contusion zones. In Group II, patients were put on a ventilator and inflammatory changes in the lungs were revealed in 30 patients (79%). Lung rupture associated with the contusion was revealed in 2 (5.2%). When comparing the groups by the composition of the isolated microflora, it was found that in patients of group II, Acinetobacter spp was more often found (46.7% vs. 17.1% in group I patients, p=0.021) and Enterococcus spp. (30.0% and 8.6%, respectively, p=0.058), as well as Klebsiella pneumoniae (46.7% and 37.1%, p=0.6). At the same time, Staphylococcus aureus was not found in these patients, while it was detected in 14.3% of patients from Group I (p=0.09). Medical care in Group I was carried out according to the principles of the “golden hour”: within the first hour from the moment of admission to the patients with the presence of pneumothorax and hemothorax, the pleural cavity was drained. In Group II, this procedure was performed in other medical institutions and in 5 additional patients at the Institute.Conclusions.Early computed tomography diagnosis of multisystem trauma makes it possible to assess the severity of injuries to the chest organs and other areas of the body and determine the treatment tactics. A comprehensive approach to the management of patients, including early diagnosis of trauma, drainage of the pleural cavity, determination of management tactics, bacterial test of the lower respiratory tract discharge, helps reduce infectious complications by an average of 45.46%.

Aortic esophageal fistula (AEF) is a rare but extremely life-threatening condition requiring immediate surgical treatment. The mortality rate among such patients may exceed 60 %, including after surgical treatment. Etiological and pathogenetic mechanisms of AEF are complex and various, but in most cases, they are associated with chronic aortic diseases. The second group of etiological factors of AEF includes trauma of esophagus wall by foreign bodies, malignant neoplasms of the esophagus or mediastinum. AEF may also occur as a result of surgical interventions on the aorta and esophagus. The difficulties of early diagnosis are primarily associated with non-specific clinical manifestations of AEF and the lack of unified protocol for the examination of patients with the first-time upper gastrointestinal tract bleeding. The described reasons in some cases can lead to an inaccurate diagnosis, which entails a loss of time. Among the instrumental diagnostic methods, the most informative is the combination of esophagogastroduodenoscopy and computed tomography of the chest with intravenous contrast enhancement. Each of these methods has its advantages and disadvantages, and allows to identify a number of direct and indirect signs of pathological communication between the aorta and the esophagus.

The purpose of the study. To analyze possibilities of computed tomography (CT) for esophageal injuries and their complications as part of a differentiated approach to the choice of a minimally invasive treatment method.Materials and methods. The results of CT scans were analyzed in 25 patients with esophageal injuries of various etiologies who were treated at the N.V. Sklifosovsky Research Institute of SP in the period 2019–2020. CT was performed with oral and intravenous bolus contrast, primarily at admission and in dynamics, a total of 77 studies.Results. In all cases, direct and indirect CT signs of esophageal damage were detected, and the degree of involvement of surrounding organs and tissues in the pathological process was assessed. Based on the data obtained, the following variants of esophageal damage and its complications were identified: intramural esophageal hematoma (2); rupture of the thoracic esophagus without the development of purulent complications (2); rupture of the thoracic esophagus complicated by the development of mediastinitis (4); rupture of the thoracic esophagus with the development of mediastinitis and pleural empyema (13); rupture of the cervical calving of the esophagus, complicated by phlegmon of the neck and descending mediastinitis (4). Different patient management tactics were used for each variant. Thus, the selection and sequence of minimally invasive interventions, such as thoracoscopic sanitation mediastinal and pleural cavity, esophageal stenting, percutaneous endoscopic gastrostomy (CEG) and endoscopic vacuum aspiration system (E-VAS), were carried out taking into account CT data, including observations in dynamics.Conclusion. CT scan for esophageal injuries allows you to get complete information about both the nature of esophageal damage and its complications, to determine their type, localization and volume. CT data allow us to justify a minimally invasive approach in the treatment of esophageal injuries, to determine the order of interventions. CT studies performed in dynamics allow us to evaluate the effectiveness of treatment and to carry out timely correction of tactics.

Relevance. The variety of options for combining injuries and disorders occurring in the body with a combined injury, the need for rapid decision-making on treatment require rapid diagnosis of the entire volume of injuries and determining the severity of the injury, but there is still no single protocol for examining such victims.The aim of the work was to present a modern CT study protocol for patients with concomitant trauma. Materials and methods. The results of computed tomography of 30 patients with severe concomitant trauma were analyzed. All the victims were admitted in the first hours after the injury. Men were 30 (67 %), women – 10 (33 %), the average age was 41.3 ± 7.6 (22–79) years. Traditional multiphase full-body MSCT was performed in 20 patients, in 10 patients a special protocol was used for the study of the "whole body" by the method of divided bolus. The results of the study. Craniocerebral injuries were detected in 15 (50 %), spinal injuries – in 7 (23.3 %). Simultaneous injuries to the chest and abdomen were detected in 19 (63.3 %) of the victims. When subjectively evaluated, the quality of the images obtained using the full-body MSCT protocol with bolus separation and the standard multiphase protocol for the diagnosis of traumatic injuries was equivalent. The average radiation load per patient with traditional multiphase full-body MSCT is 66 % higher than with the split-bolus protocol. Conclusions. Full-body MSCT using a split bolus is a modern technique that fully meets the diagnostic conditions for severe combined trauma and, with a decrease in the radiation dose, allows you to determine all possible injuries in the victim in a single study.
