Abstract:
Objective To investigate the efficacy and safty of percutaneous transluminal angioplasty (PTA) of renal artery stenosis resulting from fibromuscular dysplasia.Methods A total of 32 patients with fibromuscular dysplasia complicated with hypertension in level 2 to 3 or refractory hypertension were enrolled,who underwent PTA.The blood pressure,types of medication,restenosis,survival rates and complications were observed after treatment.Results Technical success rate of PTA was 93.94％ (31/33).The blood pressure decreased from (189.6±26.0)mmHg/(121.6± 21.7)mmHg before operation to (136.6±8.0)mmHg/(81.1±11.5)mmHg after operation (t＝9.117,7.745,both P＜ 0.001).No renal artery rupture,interlayer,branch blockage,thrombosis and other related complications and postoperative adverse events occurred.All patients were followed up for 5 months to 100 months,with an average of (40.4±26.1) months.Survival rate was 100％ (32/32).Conclusion PTA is safe and effective for treating renal artery stenosis from fibromuscular dysplasia.
