A Rare Case of Coil Migration into the Duodenum after Embolization of a Right Colic Artery Pseudoaneurysm

Abstract

Transcatheter arterial embolization is a safe and effective treatment for visceral artery aneurysms; nevertheless, some complications can occur. Coil migration to other organs after embolization is extremely rare, and only 16 cases have been reported previously. We report a rare case of coil migration to the duodenal lumen after embolization of a right colic artery pseudoaneurysm. To the best of our knowledge, this is the first case of coil migration after a right colic artery embolization. The patient exhibited no symptoms and was treated conservatively without any intervention. Some previous reports have demonstrated spontaneous coil passage and successful conservative management. Our case supports conservative treatment as the primary treatment for asymptomatic patients. Clinicians should assess the risks and benefits of coil removal in asymptomatic patients before performing any intervention. Clin Endosc 2021 Jan 12.

Case report: Duodenal obstruction caused by gastroduodenal artery pseudoaneurysm with hematoma: an unusual case and literature review

“…Coil embolization is the most commonly used endovascular treatment. It involves embolization of aneurysm as well as proximal and distal arteries, with a potential complication of coil migration when used in large saccular aneurysm or when there is infection, inflammation, or malignancy around the pseudoaneurysm ( 31 , 32 , 34 ). Embolization with liquid embolic agents carries the risk of distal embolization and is therefore more technically challenging.…”
