Ileal Arteriovenous Malformation after Laparoscopic Right Hemicolectomy Successfully Treated with Interventional Radiology: A Case Report

In colorectal surgery, newly detected aneurysm-like mesenteric vascular lesions during postoperative surveillance may be difficult to distinguish from aneurysms, pseudoaneurysms, AVMs, and AVFs.
