Abstract

While surgical treatment for abdominal aortic aneurysm (AAA) is a standard operation, prevention of complication is important. Intestinal ischemia of the sigmoid colon and/or rectum after AAA surgery is severe and has a high mortality rate although occurrence frequency is low. The most important thing to prevent is the preoperative and intraoperative evaluation of the left hemicolon and rectal circulation. Measurement of inferior mesenteric artery stump pressure is also useful. From the viewpoint of prevention of buttock claudication, it is desirable that internal iliac artery (IIA) blood flow is preserved, but aggressive IIA reconstruction adaptation is considered to be low. For erectile function, it is important that the antegrade blood flow from the IIA to the internal pudendal artery on at least one side is preserved or reconstructed. To prevent retrograde ejaculation, it is important to preserve the superior hypogastric plexus and one side of the lumbar splanchnic nerve, and the hypogastric nerve. Understanding and mastering local anatomy and pathophysiology is important in preventing complications, and we must also remember that we always keep watchful surgical operations in mind in order to prevent tissue damage.
