A 32-year-old member asked:

can you tell me how atherectomy deal with severe peripheral arterial disease?

Dr. Omar Esponda
Internal Medicine 15 years experience
Might help symptoms: Atherectomy refers to the physical removal of plaque material from a blood vessel. If you have an obstruction in one of your arteries your doctor might use this method to open the artery to bring more blood flow to the affected area and reduce symptoms associated with obstruction such as pain upon walking and pain at rest.
Dr. Stephen Hofkin
Radiology 28 years experience
Removing plaque: Atherectomy is the removal of plaque build up in the lining of an artery. The plaque causes a narrowing of the arterial lumen decreasing blood flow. By removing the plaque, there is increased flow in that artery. It can be done by a variety of techniques: using a laser, or devices that act like a plane to shave the plaque and others that are like a drill or file.

With immediate...: With immediate switch surgery, they do very well, usually without any consequences at all. Delayed surgery carries significant risks, however.

Carotic Arteries: The human carotid arteries supply the head and the neck with oxygenated blood. The left common carotid artery originates from the aorta and the right common carotid originates from the brachiocephalic artery which originates from the aorta. The carotic artery divides in the neck to form the internal and external carotic arteries.

Most common:femoral: In the US most angiograms and angioplasties (and stents) are accessed via the femoral artery at the groin. The radial approach is growing in usage but I believe it accounts for only about 5% of cases.

How are arteries affected by atherosclerosis?

2 doctor answers6 doctors weighed in
Dr. Michael Fenster
Cardiology 31 years experience
In degrees: Atherosclerosis affects the arteries in varying degrees and stages. One of the first manifestations is an attenuation or loss of the normal dilatory response of arteries. They also become progressively stiffer and as they accumulate more and more internal debris the flow becomes more turbulent. Increasing activation of the inflammatory process is noted, with resultant clots and their sequelae.

What's the purpose of the coronary arteries?

4 doctor answers9 doctors weighed in
Dr. Stuart Higano
Cardiology 37 years experience
Coronary arteries: Coronary arteries run on the surface of the heart and provide blood to the heart muscle. As a contracting muscle, the heart needs a continuing supply of nutrients like oxygen, glucose, fatty acids. If coronary blood flow is slowed or interrupted, such as by a coronary narrowing or a blood clot, the heart muscle will suffer and the patient will feel chest pain or there will be a heart attack.
