Renal artery stenosis is a blockage of an artery to the kidneys, which may ultimately lead to kidney failure and hypertension (high blood pressure). In most cases, this blockage is caused by atherosclerosis, the build-up of cholesterol deposits (plaque) in arteries, but also may be caused by conditions such as fibromuscular dysplasia, which involves abnormal cellular development in artery walls, and Takayasu's arteritis, an inflammatory disease that affects the aorta and its branches, including the renal arteries.
The Brigham and Women’s Hospital (BWH) Division of Vascular and Endovascular Surgery provides advanced diagnosis and treatment for patients with renal artery disease. State-of-the-art techniques, including endovascular treatment of renal artery stenosis, are available for our patients. Part of the Heart & Vascular Center, we are an international referral site with broad experience managing vascular problems, ranging from the most common to the rare and complex. Twenty-four-hour consultation is available for urgent or emergency problems.
There are a variety of factors that could put you at risk for developing renal artery stenosis; the most common are:
Keep in mind that although these factors increase a person's risk, they do not necessarily cause the disease. A patient with several of these risk factors may never develop the disease, while others with no known risk factors may develop the disease.
Common symptoms of renal artery stenosis include:
Specialists from the Division of Vascular and Endovascular Surgery develop individualized treatment plans for renal artery stenosis patients based on:
The first option is to treat peripheral arterial disease medically. Along with a modification of lifestyle risk factors, this may include:
Procedures and Surgery
If it is determined that renal function is extremely impaired and medical treatment has failed to control hypertension, interventional (minimally invasive) or surgical treatment will be recommended.
The Heart & Vascular Center is located in the Shapiro Cardiovascular Center, across the street from BWH’s main 75 Francis Street entrance. The Heart & Vascular Center brings together the full range of services in one location, fostering seamless and coordinated care for all cardiovascular patients.
If you are having surgery or a procedure, you will likely be scheduled for a visit to the Watkins Clinic for pre-operative information and tests.
The day of your procedure, you care will be provided by physicians, anesthesiologists and nurses who specialize in surgery for patients with renal artery stenosis. After surgery, you will go to the post-surgical care unit where you will receive comprehensive care by an experienced surgical and nursing staff.
During your procedure, family and friends can wait in the Shapiro Family Center. Staff members will provide surgery updates and caregivers who leave the hospital will be contacted by cell phone.
Patients benefit from the teamwork of vascular and endovascular surgeons, medical cardiologists, interventional cardiologists, cardiovascular imaging experts and radiologists, and anesthesiologists, all experts in peripheral artery disease. They work alongside nurses, physician assistants, physical therapists, dietitians and social workers to achieve outstanding outcomes for our patients.
For over a century, a leader in patient care, medical education and research, with expertise in virtually every specialty of medicine and surgery.
