Surgical removal of acute occlusions of the abdominal aorta and its branches

Acute occlusion of the terminal abdominal aorta and its main branches (renal, mesenteric and iliac arteries) is one of the most severe and difficult to surgically treat types of emergency vascular pathology. According to sectional data, it is detected in 0.15-2% by autopsy [18, 19] or in 8-9 patients out of 10 thousand admitted to hospitals of all profiles [18]. In recent decades, these indicators have tended to increase continuously [5, 6, 9, 13]. Mortality reaches 80% in acute thrombosis of the aorta and mesenteric arteries [2, 8, 11]. In these cases, anticoagulant therapy without restoring blood flow is usually ineffective [2, 4, 5, 10].
