Commentary: The sandwich technique to preserve the hypogastric artery during EVAR.

摘要

Compromise of the distal common iliac artery (CIA) represents a problem to the operator performing endovascular aneurysm repair (EVAR) of the abdominal aorta or/and the iliac arteries. Distal CIA landing zones need to be long enough to secure fixation and sealing. Among the most common techniques to prevent retrograde flow from the internal iliac artery (IIA) when an aortic endograft needs to be extended to the external iliac artery (EIA),1'2 coverage of the ostium3 or proximal emboli-zation using coils or occluders4 is better tolerated than more extensive coil emboliza-tion with occlusion of the branches. The latter is accompanied by more frequent buttock claudication and other complications.
