Fatal coil migration into the stomach 10 years after endovascular celiac aneurysm repair.

ABSTRACT

Celiac trunk aneurysms are rare and can be treated with coil embolization. Migration of the coil with erosion of the arterial wall and further perforation to an extravascular structure, although infrequent, can occur. The authors describe a lethal aortogastric fistula in a patient who had undergone embolization of a celiac trunk aneurysm with tungsten coils and alcohol prolamine solution 10 years earlier. Gastroscopy, performed due to acute hematemesis, showed the coil placed 10 years previously inside the stomach without active bleeding. Two days later, the patient died of a recurrent gastrointestinal bleeding. Autopsy showed abscess formation at the celiac trunk resulting in an aortogastric fistula. The authors discuss the possible cause of this remote complication of the embolotherapy.
