Renal artery stenting is a procedure in which a stent is placed in the renal artery. This is helpful to treat renal artery disease.

Renal artery disease is caused by the narrowing of the arteries leading to one or both kidneys. This narrowing can also be called stenosis. It is usually caused by a build-up of fat or calcium deposits called plaque. Over time this plaque can lead to total blockage of an artery.

Due to blockage of the renal artery, the kidney doesn’t receive sufficient blood supply which activates renin – the angiotensin system, and ultimately leads to increase blood pressure, which not maintain by two or three antihypertensive medicines.

A minimally invasive procedure performed by an Interventional radiologist through the groin. A thin tube was inserted (Catheter) into the artery and a small balloon inflated in the artery. The balloon has a small mesh tube called a stent wrapped around it. It expands the stent in the artery which keeps the artery open and helps prevent further narrowing.

Renal artery stenting can be improved blood flow toward the kidney and gradually decrease blood pressure and the requirement of excessive medications.
