随着我国高血压和糖尿病(DM)发生率的增加,动脉粥样硬化性肾动脉狭窄(atherosclerotic renal artery stenosis,ARAS)在肾动脉狭窄(RAS)的构成比从1990年前的28·9%增至1990年后的71·1%,成为RAS的首要病因[1]。当肾动脉直径减少达到50%或以上时定义为RAS,当管腔直径减少达到70% As the incidence of hypertension and diabetes mellitus (DM) increases in our country, the incidence of atherosclerotic renal artery stenosis (ARAS) in renal artery stenosis (RAS) has increased from 28.9% To 71.1% after 1990, becoming the leading cause of RAS [1]. When the renal artery diameter reduction of 50% or more is defined as RAS, when the lumen diameter reduced to 70%
