# A Surgical Case of an Abdominal Aortic Aneurysm With a Meandering Inferior Mesenteric Artery due to Superior Mesenteric Artery Occlusion

## TL;DR

A 78-year-old man underwent successful abdominal aortic surgery with a special technique to manage a meandering mesenteric artery.

## Contribution

A novel surgical method using intraoperative inferior mesenteric artery perfusion is introduced for complex aortic cases.

## Key findings

- Intraoperative inferior mesenteric artery perfusion ensured adequate intestinal blood flow.
- The patient had a favorable postoperative recovery using this surgical technique.
- The method proved to be easy and effective for abdominal aortic surgery in complex cases.

## Abstract

A 78-year-old man was diagnosed with an abdominal aortic aneurysm with a meandering mesenteric artery. We performed abdominal aortic replacement and inferior mesenteric artery reconstruction using intraoperative inferior mesenteric artery perfusion during surgery. A 4-Fr arterial sheath was inserted into the left brachial artery, and a 10-Fr balloon catheter was inserted into the inferior mesenteric artery for perfusion. The intraoperative intestinal blood flow was satisfactory, and the patient's postoperative course was favorable. This method was an easy and effective option for abdominal aortic surgery in patients with a meandering mesenteric artery.
