Iliac branch endoprosthesis for the treatment of a complex aneurysm.

Decisions pertaining to the management of an abdominal aortic aneurysm in combination with bilateral internal iliac aneurysms present quandaries during endovascular intervention. This report outlines an endovascular aortic repair method for endovascular aortic repair involving an abdominal aortic aneurysm with bilateral iliac aneurysms. The patient exhibited aneurysmal dilatation of the abdominal aorta, bilateral common iliac arteries, and bilateral internal iliac arteries. There was a short distance from the lowest renal artery to the iliac bifurcation, coupled with tortuous bilateral external iliac arteries. Due to the patient's unique anatomical conditions, we performed an abdominal aortic endovascular repair, along with endovascular repair of the bilateral common iliac arteries, embolization of the right internal iliac artery, and reconstruction of the left internal iliac artery using a GORE iliac branch endoprosthesis. Postoperative computed tomography angiography performed 1 month later revealed complete exclusion of the aortic aneurysm, proper positioning of the stent graft, normal morphology, successful closure of the right internal iliac artery, and clear blood flow in the left iliac artery.
