目的分析近17年来肾动脉狭窄病人的临床特征和介入治疗情况的变化。方法分时间阶段对比总结1987-2004年间144例肾动脉造影患者的临床特征及介入治疗的情况。结果肾动脉造影人数在逐年增多,2000年以前病例平均年龄较小(P<0.05),高血压为主要就诊原因,主要病因是大动脉炎(占52.3%);2000年以后出现因急性肺水肿等行肾动脉造影的病例,动脉粥样硬化病因为主(占70.7%),介入治疗的比例和技术成功率升高(P<0.05),且介入治疗方式由单纯球囊扩张为主变为球囊预扩张后支架植入为主(P<0.05)。结论17年来肾动脉狭窄的病因学和临床特征及其介入治疗均发生了明显变化。
Objective To analyze the clinical features and interventional treatment of renal artery stenosis in the past 17 years. Methods The clinical characteristics and interventional therapy of 144 patients with renal artery angiography during 1987-2004 were summarized and compared in different time periods. Results The number of renal artery angiography was increasing year by year. The average age of patients before 2000 was smaller (P <0.05). Hypertension was the main cause of treatment. The main cause was arteritis (52.3%). Acute pulmonary edema occurred after 2000 Renal artery angiography cases, the main cause of atherosclerosis (70.7%), the proportion of interventional therapy and the technical success rate increased (P <0.05), and the interventional treatment by a simple balloon dilatation into the ball Pre-dilatation balloon stent implantation (P <0.05). Conclusion The etiology, clinical features and interventional treatment of renal artery stenosis have changed significantly in 17 years.
