Overview

Surgery

If Renal artery stenosis (RAS) advances until the artery is nearly or completely blocked, the patient may need surgery to open up the flow of blood to the kidney. Different types of surgery for RAS include the following:

Endarterectomy

In an endarterectomy, a vascular surgeon removes the plaque.

Bypass surgery

To create a bypass, a vascular surgeon uses a vein or synthetic tube to connect the kidney to the aorta. This new path serves as an alternate route for blood to flow around the blocked artery into the kidney.

-When high-grade renal artery stenosis is documented and blood pressure cannot be controlled with medication, or if renal function deteriorates, renal artery stenosis is often treated invasively. Renal artery stenosis is most commonly treated by endovascular techniques (i.e. [[angioplasty]] with or without [[stent]]ing). A 2003 [[meta-analysis]] found that angioplasty was safe and effective in this context.<ref>{{cite journal |author=Nordmann AJ, Woo K, Parkes R, Logan AG |title=Balloon angioplasty or medical therapy for hypertensive patients with atherosclerotic renal artery stenosis? A meta-analysis of randomized controlled trials |journal=Am. J. Med. |volume=114 |issue=1 |pages=44-50 |year=2003 |pmid=12557864 |doi=}}</ref> There are ongoing clinical trials to compare medical management and angioplasty with stenting to medical management alone. These include CORAL and ASTRAL, both scheduled to report results in 2010. In addition to endovascular treatment, surgical resection and anastomosis is a rarely-used option.
