Abstract

One of the most severe complications in the long-term period after reconstructive operations on the abdominal aorta is aortoenteric fistula, the lethality in the formation of which is over 90%. To date, there are no methods for preventing this condition in the literature, there are only instructions for combating an already developed complication, the mortality rate in radical surgical treatment of which also remains extremely high (9–17%). Based on their own experience (174 patients), the authors planned the stages of the pathogenesis of a duodenal defect with the subsequent formation of an aortoenteric fistula, and developed a scheme for the primary prevention of complications. Observations of operated patients (since 2012) have shown that the proposed method of prevention is an effective way to prevent fatal bleeding from the area of the central anastomosis between the abdominal aorta and an artificial blood vessel.
