Abstract

Purpose: Visceral venous aneurysms are rare, especially in the inferior mesenteric vein (IMV). We report a giant IMV aneurysm secondary to an iatrogenic arteriovenous fistula (AVF).

Case report: A woman presented with an incidental finding of a 7 cm large IMV aneurysm and an inferior mesenteric arteriovenous shunt. The patient underwent successful endovascular occlusion of the shunt to avoid aneurysm rupture and portal hypertension.

Conclusion: Embolization is a possible treatment strategy for mesenteric venous aneurysms with an AVF.

Clinical impact: We describe an unusual mesenteric AV-shunt from a surgical crush injury that caused a giant venous mesenteric aneurysm and offer technical aspects on minimally invasive endovascular treatment.
