肾动脉狭窄可引起肾血管性高血压及缺血性肾病,其主要原因有3种:动脉粥样硬化、纤维肌性发育不全及大动脉炎。年轻者多见于后两种疾病,而年老者以动脉粥样硬化居多。随着社会生活水平的提高、全球人口老龄化,动脉粥样硬化性肾动脉狭窄(atherosclerotic renal artery stenosis,ARAS)的发生率不断增加,ARAS已成为导致终末期肾脏疾病的常见原因,占老年性高血压患者的10%~40%[1]。ARAS为进展性疾病,及时纠正ARAS后,部分患者不仅能纠正高血压,而且能保护受损的肾功能,使ARAS成为少有的老年性高血压和慢
Renal artery stenosis can cause renal vascular hypertension and ischemic nephropathy, there are three main reasons: atherosclerosis, fibromuscular hypoplasia and aortitis. The younger are more common in the latter two diseases, while the elderly are mostly atherosclerosis. With the improvement of social life, the global population is aging and the incidence of atherosclerotic renal artery stenosis (ARAS) is increasing. ARAS has become a common cause of end-stage renal disease, 10% to 40% of patients with hypertension [1]. ARAS is a progressive disease, timely correction of ARAS, some patients not only can correct high blood pressure, but also protect the damaged kidney function, make ARAS rare and slow
