Treatments for Renal Artery Stenosis
Initial treatment for renal artery stenosis is often medication. The condition may require three or more different drugs to control high blood pressure. Patients may also be asked to take other medications, such as cholesterol-lowering drugs and aspirin.
In some cases, an intervention such as angioplasty, often with stenting or surgery, may be recommended. With angioplasty, a catheter is inserted into the body through a blood vessel and guided to the narrowed or blocked renal artery. A balloon on the catheter is then inflated to open up the inside of the artery. A stent can then be placed to keep the area open.
Surgery to bypass the narrowed or blocked portion of the artery and/or remove a non-functioning kidney may be done for some patients.
If you’re diagnosed with renal artery stenosis, it’s important to discuss the risks of the different treatments with your doctor. The side effects of blood pressure medications include dizziness, sexual problems, headache, and cough. Complications of angioplasty include bruising, bleeding, additional kidney damage, and the possibility that the arteries can close again
