Parallel Stent Graft Technique for Hypogastric Aneurysm Repair With Flow Preservation of Distal Pelvic Circulation

Hypogastric artery aneurysms (HAA) necessitate repair due to significant morbidity and potential mortality associated with rupture. Coverage or coiling of HAA are not always possible, as the risk of pelvic and spinal cord ischemia become especially significant in bilateral hypogastric disease as well as with prior extensive aortic coverage. We report 2 cases of endovascular HAA exclusion using parallel stent grafts for preservation of flow through the distal hypogastric artery branches and external iliac artery in patients with prior thoracic and abdominal aortic repairs, contralateral hypogastric disease, and significant anatomic constraints
