Reverse crossover chimney technique combined with endovascular aneurysm repair treating abdominal aortic aneurysm
Abstract：Objective To investigate the curative effect of reverse crossover chimney technique combined with endovascular aneurysm repair treating abdominal aortic aneurysm.Methods Three cases (3 males,average age:57,66,65 years old) received endovascular aneurysm repair(EVAR) and reversed crossover chimney technique in abdominal aortic aneurysm.The vascular stent was sent from contralateral femoral artery.After intervention,digital subtraction angiography showed that abdominal aortic aneurysm was repaired ; bypass-stent and ipsilateral inner iliac artery were unobstructed.Results Contrast medium was fully filled in abdominal aorta and the abdominal aorta was well displayed in 2 cases using bypass-stent,ENDURANT (Medtronic,USA) or EXCLUDER (GORE,USA).The ipsilateral inner iliac artery was also well displayed.Abdominal aorta was obstructed in the opening of the iliac artery in one case with Zenith(COOK,USA) stents.One month later,computed tomography angiography(CTA) showed that there were no endoleaks or displacement in all three cases.Conclusion For patients with abdominal aortic aneurysm,if bilateral inner iliac arteries are involved,reverse crossover chimney technique after EVAR can protect unilateral inner iliac artery from being obstructed.
