Superior mesenteric artery injury during en bloc excision of a massive left adrenal tumor

Abstract

Superior mesenteric artery (SMA) injury is a rare event during abdominal surgery. We report the first case of inadvertent injury of the superior mesenteric artery during surgery of a large malignant adrenocortical tumor with inferior vena cava thrombus. The cause of inadvertent injury was anatomical distortion of the great vessels due to the massive nature of the tumor. The case was managed successfully by immediate end-to-end anastomosis of the superior mesenteric artery.
