Acute pancreatitis following segmental pancreatic resection associated with portal vein thrombosis and aneurysm of the spleno-mesenteric venous confluence.
Vascular abnormalities associated with acute pancreatitis are well-known and reported in the literature in up to 50% of the patients with acute necrotizing pancreatitis. Most reported vascular abnormalities are superior mesenteric and/or portal vein thromboses and arterial pseudo-aneurysms. Portal vein aneurysm and/or spleno-mesenteric venous aneurysm are rare entities. Furthermore, portal vein aneurysm can be complicated by portal vein thrombosis. We report a case of spleno-mesenteric vein aneurysm that unusually followed portal vein thrombosis and was secondary to postoperative pancreatitis following segmental pancreatic resection for a well-differentiated endocrine carcinoma. The patient was treated successfully with conservative treatment, although he developed a hepatic abscess two months after his treatment.
