The study of blood supply to the left half of the colon to prevent ischemic complications in resection of infrarenal abdominal aortic aneurysm
With the purpose to study the blood supply to the left half of colon the experimental study on 18 human cadavers and clinical study of two groups of patients who underwent resection of infrarenal abdominal aortic aneurysm with and without the use of prophylactic measures to prevent ischemic complications of the left half of the colon were realized. Experimental study on human cadavers showed that by the value in the blood supply to the distal descending colon, sigmoid colon and rectum the 2nd place in percentage internal iliac arteries have occupied. Among operated on for infrarenal abdominal aortic aneurysm without the use of objective methods for the prevention of ischemia of the left half of colon chronic ischemia developed in 12 (30%) cases. The proposed package of measures of preoperative examination and intraoperative method of measurement of the retrograde pressure in inferior mesenteric artery with clamping the internal iliac arteries can determine the indications for reimplantation of the involved arteries into the vascular prosthesis branches at resection of abdominal aortic aneurysm and get encouraging results.
