Abstract:
Gastrointestinal bleeding caused by arteriovenous malformation (AVM) of the pancreas is extremely rare. A 56-yr-old man with AVM of the head of the pancreas who was presented with recurrent episode of melena is described herein. The preoperative diagnosis was confirmed by angiographic study, and he was successfully treated with pancreatoduodenectomy. Histological examination of the resected specimen revealed pancreatic AVM involving the adjacent duodenal wall.
Insights
Gastrointestinal bleeding from pancreatic arteriovenous malformations (AVMs) is rare. This case report details a 56-year-old man with recurrent melena successfully treated with surgery for a pancreatic head AVM.
Area of Science:
- Gastroenterology
- Vascular Surgery
- Surgical Oncology
Background:
- Pancreatic arteriovenous malformations (AVMs) are rare vascular anomalies.
- Gastrointestinal bleeding is a potential, though infrequent, complication of pancreatic AVMs.
Observation:
- A 56-year-old male presented with recurrent melena (dark, tarry stools).
- The patient was diagnosed with an arteriovenous malformation (AVM) in the head of the pancreas.
Findings:
- Preoperative diagnosis was confirmed via angiographic study.
- Surgical resection using pancreatoduodenectomy was performed successfully.
- Histological examination confirmed the pancreatic AVM involved the adjacent duodenal wall.
Implications:
- This case highlights the importance of considering pancreatic AVMs in patients with obscure gastrointestinal bleeding.
- Successful surgical management of pancreatic AVMs can resolve recurrent bleeding.
- Understanding the extent of AVM involvement is crucial for surgical planning.
