![]() ![]() When your weight increases, so does your blood pressure. These operations are most often done if angioplasty isn't successful, or when there's a need for additional surgical procedures.Īs a part of your treatment plan for renal artery stenosis, your doctor may recommend making certain lifestyle changes: Sometimes this means connecting the renal artery to a vessel from somewhere else, such as the liver or spleen. During a bypass procedure, doctors graft a substitute blood vessel to the renal artery to make a new route for blood to reach your kidneys. In this procedure, doctors widen the narrowed renal artery and place a device (stent) inside your blood vessel that holds the walls of the vessel open and allows for better blood flow. Procedures to treat renal artery stenosis may include: Procedures to open the vessel should be considered for people who don't do well on medicine alone, who can't tolerate medications, who often retain fluids and who have treatment-resistant heart failure. Results from clinical trials comparing medication with renal angioplasty and stenting didn't show a difference between the two treatment approaches on reducing high blood pressure and improving kidney function for people with moderate renal artery stenosis. ![]() Proceduresįor certain people a procedure may be recommended to restore blood flow through the renal artery to improve blood flow to the kidney. Which medications are best for you depends on your individual situation. If atherosclerosis is the underlying cause of renal artery stenosis, your provider may also recommend aspirin and a cholesterol-lowering medication. Calcium channel blockers, which help relax blood vessels.Beta blockers and alpha-beta blockers, which may have the effect of making your heart beat slowly and less forcefully or widening (dilating) your blood vessels, depending on which medication you use.Diuretics, also known as water pills, which help your body eliminate excess sodium and water.Angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs), which help relax your blood vessels and block the formation or effects of a natural body chemical called angiotensin II, which narrows blood vessels.Some medications commonly used to treat high blood pressure associated with renal artery stenosis include: Finding the right medication or combination of medications may require time and patience. High blood pressure - even when mainly related to renal artery stenosis - often can be successfully treated with medications. If your blood pressure is moderately or severely elevated, a healthy lifestyle - limiting salt, eating healthy foods and getting regular physical activity - can help control your blood pressure. Depending on your overall health and symptoms, you may not need any specific treatment. Sometimes a combination of treatments is the best approach. Treatment for renal artery stenosis may involve lifestyle changes, medication and a procedure to restore blood flow to the kidneys. This test is mainly done if it's also likely that you need a small tube (stent) placed in your blood vessel to widen it. Before an X-ray is taken, your doctor injects a dye into the renal arteries through a long, thin tube (catheter) to outline the arteries and show blood flow more clearly. This special type of X-ray exam helps your doctor find the blockage in the renal arteries and sometimes open the narrowed part with a balloon or stent. A dye injection into the arteries outlines blood vessels during imaging. MRA uses radio waves and strong magnetic fields to produce detailed 3D images of the renal arteries and kidneys. You may receive a dye injection to show blood flow. During a CT scan, an X-ray machine linked to a computer creates a detailed image that shows cross-sectional images of the renal arteries. This procedure also helps your doctor find blockages in the blood vessels and measure their severity. High-frequency sound waves help your doctor see the arteries and kidneys and check their function. ![]() Imaging tests commonly done to diagnose renal artery stenosis include: ![]()
