ABSTRACT
Pancreatic endocrine tumors (PETs) are relatively rare. Owing to their slow growing characteristics, an aggressive surgical approach has been considered to improve patients' survival. A case of PET with portal vein (PV) thrombus, successfully treated by distal pancreatectomy with concomitant PV resection and removal of PV tumor thrombus, preserving collateral pathways, is reported.

We report a case of inferior mesenteric arteriovenous fistula without portal hypertension or mesenteric ischemia. A 64-year-old man had developed frequent mucous diarrhea during the previous month. Colonoscopy showed highly edematous mucosa of the rectum. Barium enema demonstrated localized stricture of the same part but no evidence of malignancy. Finally we established a diagnosis by 3D-CT and selective abdominal angiography. Transcatheter arterial embolization was successfully performed. After that, his symptoms gradually improved as all abnormal findings on colonoscopy, barium enema and abdominal CT disappeared.
