Renal Artery Angioplasty

Renal artery angioplasty (percutaneous transluminal renal angioplasty, PTRA) is used to treat atherosclerotic obstruction of the renal artery. Renal artery stenosis can lead to hypertension and loss of renal function. Percutaneous transluminal angioplasty (PTA) of the renal artery has become an increasingly widespread peripheral vascular intervention for the treatment of renovascular hypertension.

Catheter-based procedures began in 1964 when Charles Dotter initially developed PTA for treating peripheral vascular atherosclerosis. Andreas Gruntzig revolutionized the technique in 1974 when he developed a soft, flexible, double-lumen balloon catheter for use in coronary arteries. PTA has since rapidly evolved into a widely used, versatile, and dependable vascular interventional technique. Excellent results may now be achieved in the renal arteries if patients are well selected and if experienced clinicians perform the procedure.
