经皮球囊血管成形术与肾动脉支架术治疗肾动脉狭窄的疗效对比观察

目的观察经皮球囊血管成形术和肾动脉支架植入术治疗肾动脉狭窄的疗效。资料和方法 112例肾动脉狭窄患者随机分为2组:A组,经皮球囊血管成形术组;B组,肾动脉支架术组。比较两组的首次手术成功率、术后6个月并发症发生率、通畅率及术后即刻再狭窄率,术后6个月血压及血肌酐变化情况。结果 B组成功率高于A组(94.64%对76.79%,P<0.01),通畅率B组高于A组(73.21%对30.36%,P<0.01),再狭窄率B组低于A组(10.71%对28.57%,P<0.01),两组并发症发生率差异无统计学意义(P>0.05)。B组高血压治愈率较A组高(P<0.01),肾动脉支架术对动脉粥样硬化所致高血压的改善情况最好,而经皮球囊血管成形术对肌纤维结构不良所致肾血管性高血压的改善情况最好。术后血肌酐B组降低不明显(P>0.05),A组显著降低(P<0.05)。A组术后TGFR、RGFR较术前显著改善(P<0.05),B组术后TGFR较术前显著改善(P<0.05);A组术后TGFR改善更明显,较B组差异有统计学意义(P<0.05)。结论肾动脉支架术操作成功率高、通畅率高、再狭窄率低,对动脉粥样硬化引起的肾动脉狭窄所致高血压改善明显,较经皮球囊血管成形术有较大优势,可作为治疗肾动脉狭窄的一种重要的介入治疗方法。

A Comparison of Therapeutic Effects between Percutaneous Transluminal Balloon Angioplasty and Renal Artery Stenting for Renal Artery Stenosis

Purpose To investigate and compare the therapeutic effects of percutaneous transluminal balloon angioplasty and renal artery stenting for renal artery stenosis.Materials and Methods One hundred and twelve patients with renal artery stenosis were divided into two groups randomly according to therapeutic strategies:Group A,treated with transcutaneous balloon angioplasty;group B,treated with renal artery stenting.The success rate,incidence of complications within 6 months after treatment,patency rate,re-stenos...
