Abstract

Type II endoleaks occur in 5% to 10% of patients who are treated by endovascular aneurysm repair. A persistent type II endoleak combined with documented aneurysm expansion is generally considered an indication for intervention. Thrombin injection directly into the aneurysm sac is described as a safe and efficient treatment option. We present a patient with a ruptured aneurysm caused by a puncture of the stent graft during computed tomography-guided thrombin injection. This case highlights a possible harmful complication of thrombin injection and emphasizes the need for caution while performing such a procedure.
