Endovascular hypogastric artery preservation during endovascular aneurysm repair: a review of current techniques and devices.

Despite the improvement in endovascular techniques, one aspect of aneurysmal disease that continues to be challenging is the management of aortoiliac aneurysms. Sacrificing the hypogastric artery (HGA) for effective treatment is not without sequelae, which may include buttocks claudication, colonic ischemia, spinal cord ischemia, as well as buttock and scrotal necrosis. This should be taken into consideration particularly in patients with previous intervention or potential additional future interventions. This review describes the current endovascular techniques for preservation of HGA perfusion.
