Preservation technique of internal iliac artery in performing endovascular aortic repair / 介入放射学杂志

ABSTRACT

Endovascular aortic repair (EVAR) has been the main treatment means for abdominal aortic aneurysm.It has become an expert consensus that in the case of abdominal aortic aneurysm that is complicated by iliac aneurysm,the preservation of internal iliac artery is necessary because it can prevent the occurrence of gluteal muscle ischemnia,sigmoid ischemia,male sexual dysfunction and other complications.In recent years,with the continuous updating of the endovascular devices it has become possible to retain the internal iliac artery in the performance of EVAR.At present,the reconstruction of internal iliac artery in EVAR includes a variety of techniques,including intraluminal iliac branched device (IBD) technique,sandwich technique,common iliac artery covered-stent bell-bottom (BBT) technique,external iliac artery-internal iliac artery intraluminal shunt technique (reverse chimney technique),and spring coil embolism technique.This article aims to make a summary of all the above mentioned techniques.
