Direct Transarterial Embolization Via The Deep Circumflex Iliac Artery For A Type Ii Endoleak Using A Novel Onyx (Tm) Mixture

Internal iliac artery aneurysms (IIAA) can be associated with abdominal aortic aneurysms. We describe a technique of successful transarterial embolization using a mixture of Onyx (TM) formulations in a 72-year-old with previous open and endovascular aneurysm repairs of his abdominal aorta and a residual large left IIAA causing a Type II endoleak. We demonstrate that utilization of the deep circumflex iliac artery is a safe and viable alternate route to treating IIAA when direct access is not achievable.
