Hematochezia due to arteriovenous malformation of the mesoappendix: a rare case report
Journal of Surgical Case Reports(2023)
摘要
Abstract An arteriovenous malformation (AVM) of the mesoappendix is a very rare clinical entity. The clinical features, diagnosis and management of an AVM of the mesoappendix have yet to be sufficiently explained since reports about it are scarce. We report a 57-year-old man presented with hematochezia for 2 weeks. Upper and lower endoscopic could not find the source of bleeding. Abdominal contrast-enhanced computed tomography revealed an AVM of the mesoappendix. A laparoscopic appendectomy was performed, and he had a resolution of his symptoms. Intraoperative findings and pathological results confirmed the diagnosis of AVM of the mesoappendix.
