  • Title: Giant Inferior Mesenteric Vein Aneurysm Secondary to Iatrogenic Inferior Mesenteric Arteriovenous Fistula.
    Author: Pedersen V, Ohrlander T, Frevert S, Malina M.
    Journal: J Endovasc Ther; 2024 Jun; 31(3):491-494. PubMed ID: 36154497.
    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.
