Comparison of 3-year clinical outcomes after endovascular therapy for aortoiliac artery occlusive disease between patients with and without hemodialysis: Subanalysis of the REAL-AI registry

摘要

Purpose The impact of hemodialysis (HD) on aortoiliac (AI) occlusive lesions remains unknown. Here, we report the 3-year clinical outcomes of endovascular treatment (EVT) for AI occlusive lesions in propensity-matched populations of patients who did and did not undergo HD. Methods The cohort of this large-scale, multicenter, retrospective registry study included 574 consecutive patients with AI occlusive disease. Propensity score-matched analysis was performed to compare AI occlusive lesions between patients who did and did not undergo HD. The endpoints were primary patency, assisted primary patency, and secondary patency as well as overall survival and major adverse limb events (MALEs). Results A total of 57 matched pairs of patients who did and did not undergo HD were analyzed after propensity score-matched analysis. No significant difference was observed in primary patency, assisted primary patency, secondary patency, and MALEs at 3 years. The survival rate was significantly lower in the HD group than in the without-HD group (68% vs. 93%, P = 0.03). Conclusions Although the survival rate of HD patients was poor, the results of EVT for AI occlusive lesions were reasonable in these patients.
