The aorta is the largest artery in the body which has its origin at the heart. It gives off branches to the extremities, neck, and the major organs of the body for the purpose of supplying oxygenated blood.
2. Periarterial sympathectomy or the surgical interruption of a pathway in the sympathetic nervous system by cutting out a nerve segment.
2. A procedure for opening up an artery by removing the plaque (atheroma) produced by the build-up of cholesterol and other fatty substances in the inner lining of the artery from atherosclerosis or the hardening of the arteries.
"Atherectomy is usually done in major arteries; such as, the coronary arteries within the heart muscle and the carotid and vertebral arteries leading up to the head and brain that have experienced the occlusive effects of atherosclerosis."
A bunion is a painful deformity of the bones and joint between the foot and the big toe. Long-term irritation (chronic inflammation) caused by poorly fitting and/or high-heeled shoes, arthritis, or heredity causes the joint to thicken and enlarge.
Such thickening and enlargement causes the big toe to angle in toward and over the second toe, the foot bone (metatarsal) to angle out toward the other foot, and the skin to thicken (callus formation).
Surgical removal of a bunion is usually done while the patient is under general anesthesia (asleep and pain-free) and rarely requires a hospital stay.
An incision is made along the bones of the big toe into the foot. The deformed joint and bones are repaired, and the bones are stabilized with a pin and/or cast.
A bursa is a tissue space (fibrous sac) that is lined with synovial membrane (joint tissue) and contains a small quantity of synovial fluid (joint fluid).
Bursas are found in between the tendons and the bones, skin, and bone and muscles. They function to facilitate fluid movement.
