Abstract
A 53-year-old male visited a local hospital with worsening epigastric pain. A gastrointestinal perforation was suspected and he was therefore referred to our hospital. He went into shock 15 minutes after arriving at our hospital and emergency surgery was perfomed based on a diagnosis of intraabdominal bleeding. A laparotomy revealed bleeding from the middle colic artery region, and the blood vessel was ligated and transected. Postoperative abdominal angiography revealed irregularity of vessel diameter and anneurysmal changes in the anastomotic branches between the middle and left colic arteries. Considering the risk of rupturing in the future, a transverse colectomy including the aneurysm was performed. The postoperative course was uneventful, and the patient was discharged in a good condition on day 61 after the initial surgery. Considering the multiplicity of middle colic artery aneurysms, it is important in such situations to confirm whether or not this is the case.
