Renal Artery Stenosis
Renal artery stenosis is narrowing of an artery that supplies blood to a kidney. It may result from atherosclerosis or fibromuscular dysplasia. In selected cases, it contributes to difficult-to-control high blood pressure or impaired kidney function.
Symptoms
It may cause no obvious symptoms. Clues can include severe or resistant hypertension or deterioration in kidney function.
How interventional radiology treats it
Angioplasty uses a balloon to widen the narrowed artery. A stent may be used in selected patients. Imaging helps confirm the narrowing. Not everyone benefits from an intervention; medicines and risk-factor control are often the main treatment.
Whether this treatment suits you depends on your scans and overall health. A consultation is the first step.
