A new technique for hypogastric artery embolization.

We report a new procedure for embolization of hypogastric arteries simultaneously with aortoiliac stenting. Eight patients with aortoiliac (n = 6) and iliac (n = 2) aneurysms have been treated with this procedure. The technique involves the placement of a hook catheter near the hypogastric artery or in the sac, and the endoprosthesis insertion is done by using the same arteriotomy. The endoprosthesis is deployed and the coil is released. Saline is injected into the sac. The catheter is removed and the balloon at the distal end of the endoprosthesis is inflated. Computed tomography images showed periprosthesis or aneurysm thrombosis. No endoleaks or coils displacement in the sac were found.
