Coil Migration to the Duodenum 1 Year Following Embolisation of a Ruptured Giant Common Hepatic Artery Aneurysm.

Introduction: Transcatheter arterial embolisation is often performed for the treatment of visceral artery aneurysms. Here, the case of a patient who developed the rare complication of coil migration into the intestinal tract is reported, and a review of the literature is presented.

Case report: A 30 year old woman with a ruptured giant common hepatic artery aneurysm, who had been treated with transarterial coil embolisation 1 year previously, was admitted to hospital complaining of passing the coils on defecation. Abdominal Xray and gastroscopy showed the migration of the coils through a duodenal fistula. Open repair was performed with the coils successfully removed and the duodenal fistula closed with omentopexy. At the 3 year follow up, there were no signs or symptoms of complications.

Conclusion: Based on observations from this case, although coil migration to the intestinal tract is exceedingly rare, aneurysm rupture with enteric fistula can lead to coil migration.
