经皮肾动脉成形术治疗肾血管性高血压的近期疗效

Early effects of percutaneous renal arterioplasty for treating renovascular hypertension

目的 评价经皮腔内肾动脉成形术(PTRA)治疗肾血管性高压血的近期疗效及影响疗效的因素。方法22例不同病因(大动脉炎9例,纤维肌发育不良7例,动脉粥样硬化6例)的肾动脉狭窄患者接受了PFRA术。术后造影观察即时技术成功指标并复查血压,血清肌酐水平判断PTRA的临床疗效。结果 即时造影的技术成功率达95％(21/22)。术后100％的病人高血压得到改善,8例(36％)血压降至正常,14例(64％)血压状况得到改善。9例病人肾功能得到改善。无严重并发症发生。结论 以上资料提示PTRA术近期疗效良好,是一种安全有效的治疗方法。

ve To evaluate the early effect of percutaneous transluminal renal arterioplasty (PTRA) for treatment of renovascular hypertension and the factors influencing the effect. Method PTRA was completed in 22 cases with renovascular hypertension (9 arteritis, 7 fibromuscular dysplasia and 6 atherosclerosis) . The success rate was studied with angiography. Before and after PTRA, blood pressure and serum creatinine levels were examined to evaluate the clinical result ofPTRA. Results PTRA was technically successful in 21 (95%) patients. After PTRA, the overall benefit rate (cured plus improved) for hypertension was 100% , i.e. 8 of 22 (36%) were cured and 14(64%) were improved . Renal function improved in 9 patients. There was no severe side effect. Conclusion The above results suggest that PTRA is an effective and secure method for the management of patients with renovascular hyperten-
