Inferior Mesenteric Vein Thrombosis after Proctocolectomy with Ileal Pouch-Anal Anastomosis (IPAA) and Jejunal Pouch in a Patient with Ulcerative Colitis: A Case Report and Review of Literature

Abstract

Inflammatory bowel disease (IBD) is a known risk factor for venous thrombosis. Presentation of mesenteric vein thrombosis is atypical with non-specific abdominal complaints. A high degree of suspicion is needed to diagnose the condition. Here we present a patient with inferior mesenteric vein (IMV) thrombosis following total proctocolectomy with ileal-pouch anal anastomosis (IPAA) for ulcerative colitis (UC). Computer tomography scans of the abdomen obtained early in the course revealed the less likely diagnosis of inferior mesenteric vein thrombosis. This is the first reported case of IMV thrombosis following total proctocolectomy with IPAA for UC. Early radiological diagnosis and anticoagulant therapy improved the outcome in this patient.
