Why Opt for Renal Artery Stenosis Angioplasty (Renal PTA)?
People with a narrowing in the blood vessel that brings oxygen to the kidney may have uncontrollable high blood pressure and worsening kidney function. Renal PTA is a treatment to improve blood flow through the narrowed blood vessel.
During Renal Artery Stenosis Angioplasty a series of X-rays are taken using X-ray dye. A small tube is fed up to the blood vessel feeding the kidney. A small balloon is then advanced into the narrowed area. The balloon is inflated and deflated to open the narrowing. Some times a stent is also placed in the narrowed area.
After the procedure, an overnight hospital stay is required. People have little pain after the procedure.
- Reduced need for blood pressure medication
- Improved kidney function
