What is fibromuscular dysplasia of carotid artery?

Fibromuscular dysplasia (FMD) of the carotid artery is a non-atherosclerotic and noninflammatory disease that can lead to stenosis and/or aneurysm of medium-sized arteries. FMD is a rare disease that mainly affects the distal extracranial internal carotid and renal arteries.

Is FMD a cerebrovascular disease?

Cerebrovascular FMD is mostly asymptomatic, but the most frequent neurologic manifestations include transient ischemic attack and ischemic stroke, notably in the presence of associated cervical artery dissection. Other conditions associated with FMD include subarachnoid hemorrhage and, rarely, intracranial hemorrhage.

Is FMD progressive?

In general, it is thought that FMD is not a rapidly progressive disease. This means that for most patients, the disease and its symptoms do not tend to worsen over time. Rarely, a patient may develop worsening or new symptoms, and there is a risk of developing a dissection (tear) of an artery over time.

How serious is FMD?

Fibromuscular dysplasia (FMD) affects the artery walls, making them either too weak or too stiff. This can lead to serious complications, including arterial narrowing (stenosis), weakening/bulging (aneurysm) or tearing (dissection). At least 90 percent of adults with FMD are women.

Can you live a long life with fibromuscular dysplasia?

Lifestyle Modifications for Living with Fibromuscular Dysplasia. Though FMD is a vascular disease that does not have a cure, most patients with FMD can continue to lead high quality, highly productive lives. You should talk to your FMD doctor about potential modifications to your lifestyle in order the manage FMD.

What is the basic structure of the cell membrane?

The outer membrane surrounding each cell and the membranes surrounding internal cellular organelles have a common basic structure of a lipid bilayer containing specialized proteins in association with surface carbohydrates. The most important determinant of membrane structure is the lipid component.

What is fibromuscular dysplasia (FMD)?

Fibromuscular dysplasia (FMD) is a rare blood vessel disorder in which some of the strong, flexible cells of arteries are replaced with cells that are more fibrous. Fibrous cells are less strong and also less flexible.
