Abstract
A 67-year-old man presented with sudden abdominal pain. Contrast-enhanced computed tomography showed extravasation and a pelvic hematoma measuring 5 cm in diameter. We diagnosed him with intraperitoneal bleeding, and emergency surgery was performed. Active bleeding was observed from the ileal mesentery at a site 10 cm from the terminal ileum on the oral side. Ligation was performed to control the bleeding, and adequate hemostasis was achieved. Subsequently, a cord was observed hanging from the right medial umbilical, and this cord was ligated. Based on anatomical features, we diagnosed him with bleeding from vitelline vessel remnants.
Previous reports have indicated that vitelline vessel remnants could cause ileus and were shown to be highly associated with Meckel's diverticulum. In the present case, vitelline vessel remnants caused intraperitoneal hemorrhage, although a Meckel's diverticulum was not identified. A literature search revealed no reports describing that vitelline vessel remnants cause intraperitoneal bleeding. This is the first reported case of intraperitoneal bleeding caused by vitelline vascular remnants.
