Abstract:Effective distal sealing in endovascular aorto-iliac aneurysm repair often requires landing in the external iliac artery, thus questioning the fate of the hypogastric artery circulation. Besides simple embolization to prevent a type 2 endoleak, several solutions exist for hypogastric flow preservation, each laden with increasing complexity and/or financial burden. The present study evaluated the rationale of hypogastric artery preservation in this clinical setting.
