Recanalization 24 months after endovascular repair of a large internal iliac artery aneurysm with use of stent-graft

An 83-year-old man with a large internal iliac artery aneurysm (IIAA) was t reated with the use of stent-graft, suggesting successful results at 3, 6, and 12 months after treatment. However, 24-month follow-up computed tomogra phy showed minor peripheral opacification of the IIAA. The patient underwen t surgical endoaneurysmorrhaphy. No previous report of long-term recanaliza tion of a satisfactorily thrombosed iliac artery aneurysm at 2 years or mor e after stent-grafting has been previously reported. Further follow-up stud ies need to be performed on the present procedure before anyone can confide ntly recommend it in regard to its long-term safety.
