Description

**Renovascular Hypertension Treatment – Renal Artery Stenting** Renovascular hypertension is a form of secondary high blood pressure caused by narrowing (stenosis) of the renal arteries, most commonly due to atherosclerosis or fibromuscular dysplasia. Reduced blood flow to the kidney activates the renin–angiotensin–aldosterone system, leading to persistent and often resistant hypertension. Renal artery stenting is a minimally invasive treatment option for selected patients with significant renal artery stenosis, especially those with uncontrolled hypertension despite optimal medical therapy, recurrent flash pulmonary edema, or declining kidney function. The procedure is performed under local anesthesia. Through a small puncture in the groin or wrist, a catheter is advanced into the renal artery under fluoroscopic guidance. After confirming the narrowing with angiography, a balloon may be used to dilate the stenosis (angioplasty), followed by placement of a metallic stent to keep the artery open and restore adequate blood flow. Benefits include improved blood pressure control, reduction in antihypertensive medications, stabilization or improvement in renal function, and prevention of cardiovascular complications. Most patients are discharged within 24 hours and resume normal activities quickly. Careful patient selection, imaging evaluation, and long-term follow-up are essential to achieve optimal outcomes.
