由于肾动脉狭窄使肾灌流量减少,肾素—血管紧张系统(renin-angiotensin)被激活,因而致使高血压急骤恶化,这一情况已经明了。最近血管外科也普及了血管搭桥或血管移植术(by-pass 或graft)以及通过插管进行 PTRA(经皮肾血管成形术)。因为,如果早期发现是可逆性的,可以通过 PTRA 使其扩张
It is now clear that renovascular perfusion decreases and renin-angiotensin is activated as a result of stenosis of the renal arteries, causing a sudden deterioration in hypertension. Vascular surgery has also recently become popular with by-pass or graft as well as PTRA through percutaneous nephrolithotomy. Because, if early findings are reversible, they can be expanded by PTRA
