ABSTRACT

Objective To explore the effect of endovascular re-operation on iliac limb occlusion(ILO)after endovascular aneurysm repair(EVAR).Methods Clinical data of 6 patients with ILO after EVAR from March 2018 to March 2023 were retrospectively analyzed.All the patients underwent ipsilateral femoral artery incision with Fogaty balloon thrombectomy and iliac artery balloon dilation,3 of which were combined with stent implantation and 1 of which with popliteal artery thrombectomy of Rotarex.Results The recanalization rate of the 6 patients with iliac branch occlusion was 100%(6/6).The median follow-up time was 24 months(range,6-48 months).The symptoms of lower extremity ischemia disappeared in 5 patients(Rutherford 0 grade).One patient had limb ischemia and dry gangrene(RutherfordⅢgrade).Conclusion It is necessary to carefully analyze the causes and choose personalized endovascular treatment plans for ILO after EVAR.
