Chronic portomesenteic venous thrombosis complicated by a high flow arteriovenous malformation presenting with gastrointestinal bleeding.

ABSTRACT

Portomesenteric venous thrombosis is a rare but potentially life-threatening condition. The presenting symptoms of chronic portomesenteric venous thrombosis are often non-specific but may present with variceal bleeding. We present the first reported case of chronic portomesenteric venous thrombosis causing a high flow arteriovenous malformation that resulted in extensive gastrointestinal bleeding.
