Gastric Bleeding Caused by Migrated Coil: A Rare Complication of Splenic Artery Coil Embolization

Abstract

Transarterial embolization (TAE) has emerged as the first-line treatment for visceral artery aneurysms or pseudoaneurysms-related bleeding. Coil migration is a rare and remote complication of endovascular embolization into the gastrointestinal lumen, with only fifteen cases reported upon conducting a literature review. It can occur immediately or several years after and potentially cause fatal bleeding owing to formation of aorto-enteric fistulas and infections. Here, we report a case of a patient who presented with upper gastrointestinal bleeding due to coil migration into the gastric lumen after transarterial embolization of splenic artery pseudoaneurysms.
