Abstract

Control of back bleeding from the hypogastric artery into the aneurysm after endovascular aneurysm repair (EVAR) of a ruptured aorto-iliac aneurysm may be necessary in order to avoid a type II endoleak. It is an emergency situation and selective catheterization and embolization of the hypogastric artery may be time-consuming and more importantly, it has to be performed before complete exclusion of the aneurysm has been established. We describe a plugging and sealing technique that embolizes the hypogastric artery after the exclusion of a ruptured aorto-iliac aneurysm using the embolizing agent Onyx. The mortality rate of the 16 patients treated in our institute with this technique was 25% (4/16) at 30-day and 31% (5/16) at 90-day follow up. One patient had a type II endoleak at one-year follow-up. The EVAR procedure can focus completely on controlling the acute life-threatening situation, with the embolization performed at the end of the procedure.
