Renal artery stenosis

Renal artery stenosis refers to a narrowing of a renal artery. It may be bilateral in rare cases. It's most commonly due to atherosclerosis (in elderly) and fibromuscular dysplasia (in young). It may lead to secondary hypertension and chronic kidney disease.

Management

Renal artery stenosis is managed by balloon dilatation and stenting of the stenosis. The interventional radiologist inserts a wire into the femoral artery and leads it to the renal artery. A balloon is inflated at the stenosis, after which a stent is placed.
