Pelvic Ischemia During Endovascular Abdominal Aortic Aneurysm Repair

摘要: The advent of endovascular abdominal aortic aneurysm repair (EVAR) has led to a decrease in postoperative morbidity, shorter hospital stays, and quicker recovery time following aneurysms repair. Nevertheless, EVAR continues be burdened with similar ischemic complications as seen open surgery, occurs 3–10 % patients. Signs symptoms pelvic ischemia (PI) include buttock thigh claudication (BC TC), impotence, perineal necrosis, rectal colonic distal spinal cord or lumbar plexus neuropathy. Some the mechanisms that may contribute PI interruption hypogastric arterial circulation atheroembolization. Several case reports small retrospective studies have found preservation direct internal iliac artery (IIA) perfusion is important preventing complications. incidence after 1.5 %, though multiple large series reported no cases colitis. Preserving blood flow IIAs likely key this complication, particularly presence patent inferior mesenteric artery.
