文摘目的评估支架置入重建血运治疗肾动脉狭窄的安全性与近中期临床疗效.方法 1999年至2003年,我院连续150例肾动脉严重狭窄的患者,其中男性93例(62.0%),女性57例(48.0%),年龄13～82岁,平均(52±19) 岁, 病因分别为动脉粥样硬化96例(64.0%)、大动脉炎44例(29.3%)和纤维肌性结构不良10例(6.7%),因严重高血压或伴有肾功能不全而进行了支架置入, 随诊6个月,观察手术对患者血压、肾功能的影响.结果 150例患者中,支架置入成功148例(98.7%),病变处管腔直径狭窄从65%～100%(85.5% ± 12.3%)降至0～25%(7.6%±5.2%),管腔最小直径从0～2.7 mm (1.6±0.9 mm)增至4.5～8.0 mm(6.0 ±1.1 mm).6个月随诊时, 患者血压明显下降(P<0.001), 收缩压从(169.6±32.5) mm Hg(1 mm Hg＝0.133 kPa)降至(142.7±28.1) mm Hg,舒张压从(97.3±17.8) mm Hg降至(83.3±15.2) mm Hg,服用降压药明显减少(从2.7种减至1.9种, P<0.001).其中48例(32.0%)治愈,78例(52.0%)改善, 22例(16.0%)无效.术后血肌酐改善34例(22.7%)、无变化112例(74.6%)及恶化4例(2.7%),总体上差异无统计学意义.肾动脉支架置入的手术并发症共12例(8%).6个月随诊期间无死亡.结论支架置入重建血运治疗肾动脉狭窄有较好的安全性和近中期疗效.
