Improvement of the Methods of Surgical Treatment in Patients With Infralenal Aneurysm of the Abdominal Aorta

Abstract

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.
