Duke brain, kidney, and vascular specialists diagnose and treat fibromuscular dysplasia (FMD) -- abnormal cell growth that causes narrowing, bulging, or tearing in certain arteries, most commonly those leading to the brain and kidneys. We help you manage complications such as high blood pressure and minimize the risk of kidney failure, aneurysm rupture, and stroke.
Your treatment plan will depend on your health status and the location and size of the narrowed or bulged artery.
Neurologists may prescribe drugs to lower cholesterol, lower blood pressure, prevent blood clots, treat headaches or other symptoms, and reduce your risk for serious complications.
A surgeon makes a small incision, inserts a catheter, and threads it through your circulatory system to the damaged artery. Next, a small flexible balloon is inflated, pushing against the artery walls and opening the blockage. In some cases, surgeons may recommend placing a small stent to help keep the vessel open.
In rare cases, you may need surgery to repair or replace a damaged artery. We use the most advanced and least invasive techniques possible to ensure you receive the most effective treatment.

CT and MRI Scans
High resolution, 3-D images of the brain and its blood vessels are analyzed to look for potential narrowing or bulging in arteries. These can be performed with or without contrast dye. These tests usually last from 30-60 minutes and are virtually painless. When MRI or CT scans are used to examine blood vessels (angiograms), they are called MRAs and CTAs.
Sound waves travel through a specialized wand pressed against your skin. These waves bounce off of your body’s cells and structures, creating an image that can highlight blood flow and blood vessels. This test usually lasts 30-60 minutes and is painless.
Through a small incision, a catheter is inserted into a large artery and threaded through the circulatory system. A contrast dye is injected; this highlights any areas where arteries are narrowed, blocked, or bulging. The procedure usually lasts from one to two hours and is minimally invasive.
