Do ACE inhibitors cause renal artery stenosis?

Azotemia sets in when angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs) cause efferent arteriolar dilatation, thereby decreasing intraglomerular pressure and filtration. Therefore, ACE inhibitors and ARBs are contraindicated in bilateral renal artery stenosis.

How long does a renal stent last?

The stent remains in place permanently. During the procedure, a series of X-rays, called fluoroscopy, is used to help the doctor visualize the catheter and stent inside the artery. The procedure lasts 30 to 90 minutes, depending on the severity of the narrowing.

Why are ACE inhibitors bad in renal artery stenosis?

In patients with RAS, ACE inhibitors prompt renal retention of the radiotracer due to decreased urinary output secondary to reduced GFR.

Can renal stenosis cause pain?
