Colonic venous malformation and portal hypertension: association, management, and review of the literature.
We present a case of an adolescent with lower gastrointestinal bleeding caused by a colorectal venous malformation (VM) with concomitant portal hypertension. After an episode of massive gastrointestinal bleeding, we performed an extended right hemicolectomy and resection of the VM and selective portosystemic shunt. Here, we present the case and review the literature regarding portal hypertension and gastrointestinal vascular malformations. Additionally, we discuss the physiologic and hemodynamic effects of gastrointestinal vascular malformations on the portal system.
