Arterial dysplasia

Arterial dysplasia is a term that refers to a group of conditions that affect the structure and function of the arteries. One of the most common types of arterial dysplasia is fibromuscular dysplasia (FMD), which is characterized by abnormal growth of fibrous tissue in the walls of the arteries, especially those that supply blood to the kidneys and the brain. FMD can cause high blood pressure, kidney damage, stroke, aneurysms, and dissections. FMD is more prevalent in women than men, and its exact cause is unknown.
