The aim: The retrospective analysis of the angiographic picture and clinical results of endovascular treatment of patients with postoperative abdominal and gastrointestinal bleeding was carried out. Materials and methods: The results of 447 endovascular diagnostic and therapeutic interventions in 391 patients (46 military and 345 civilians) with postoperative bleeding performed from 2012 to 2022 were studied. According to computer tomography with contrast enhancement, the source of bleeding was identified in 216 (67.7%) cases. Results: In 345 (88.2%) patients, it was possible to reliably identify the source of bleeding on angiography. In 46 (11.8%) patients with an unexplained source of bleeding, the target arterial pool was determined on the basis of localization, volume, and features of surgical intervention and considered as preventive interventions. A total of 447 endovascular hemostatic interventions were performed on 391 patients. A stent graft was installed in 27 patients, 420 embolization were performed in 364 patients. Thus, in 43 (11.0%) patients, embolization was performed repeatedly, in 12 cases - three times, in 1 case - four times. In 16 cases (15 cases of prophylactic embolization), endovascular hemostasis was ineffective and required subsequent surgical intervention Conclusions: Endovascular interventions are an effective method of diagnosis and treatment of postoperative abdominal bleeding. Prophylactic embolization allows you to prevent the recurrence of postoperative bleeding with an instrumentally undiagnosed source, however, you need to be prepared for the multi-stage treatment aimed at sequentially shutting down the collateral blood supply to the damaged area.

Introduction: Nowadays, there is an increase number of patients with abdominal aortic aneurysm. The disease has a constantly progressive nature, the result of which is the rupture of aneurysms and a high mortality rate. However, the technologies of operations are still controversial. Unidentified factors of complications and mortality remain with this pathology. The aim: to determine the risk factors of complications in patients with the aneurysm of the abdominal aorta Materials and methods: Analyze data of the examination and treatment results of 117 patients with aneurysm of the abdominal aorta. 58 patients were examined and treated according to advanced methods in a treatment group. The control group consisted of 59 patients who were examined and operated according to standard, generally - accepted methods. Results: According to our observations after the planned operations, the most common were cardiac complications. Analyzing the frequency of complications depending on the type of surgical intervention, we have not established statistically significant differences. More significant volume of blood loss was observed when performing combined operations and aorto-bifem bypass in comparison with aortic bypass and aorto-biiliac bypass. Conclusions: Combined operations result in a significantly higher blood loss compared to linear prosthetics.The level of intraoperative blood loss in patients with «large» aneurysms is significantly higher than in patients with «small» and «average» aneurysms.
