7 Facts about fibromuscular dysplasia

  1. Fibromuscular dysplasia (FMD) is a vascular disease in which there is abnormal growth in the walls of medium-sized and large arteries.
  2. FMD leads to weakness of the arterial walls, which in turn increases the risk of arterial aneurysms or arterial dissection. Also, FMD may lead to narrowing of the arterial lumen, which in turn increases the risk of stroke or heart attack.
  3. FMD is more common in females (about 90% of cases). Also, it usually affects younger and middle-aged people.
  4. Initial symptoms of FMD include; migraine, dizziness, tinnitus and elevated blood pressure.
  5. FMD usually affects the carotid artery (an artery in the neck which makes a connection between the brain and the heart) & renal arteries (which carry blood from abdominal aorta to the kidneys).
  6. The exact cause of FMD still unclear, but some studies showed that there are some predisposing factors which increase the incidence of FMD, such as hormonal and genetic factors.
  7. Management plan of FMD aims mainly to control side effects and complications (elevated blood pressure, aneurysm, dissection, stroke, heart attack… etc.).
