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.
