aterektomy

Aterectomy is a medical procedure used to remove plaque buildup from the arteries. This condition, known as atherosclerosis, occurs when fatty deposits accumulate on the inner walls of blood vessels, narrowing them and restricting blood flow. Aterectomy is typically performed when other treatments, such as medication or lifestyle changes, have not been effective or when the blockage is severe.

The procedure involves inserting a specialized catheter into a blood vessel, usually in the groin or arm. The catheter is then guided through the arteries to the site of the blockage. Once in place, a device at the tip of the catheter is used to cut away or aspirate the plaque. Different types of aterectomy devices exist, including rotational, orbital, and atherectomy catheters, each designed to address specific plaque characteristics.

After the plaque is removed, the artery is often dilated using a balloon angioplasty to further widen the vessel. In some cases, a stent may be inserted to help keep the artery open. Aterectomy is generally considered a safe procedure, but like any surgical intervention, it carries potential risks, such as bleeding, blood clots, or damage to the artery. The decision to perform an aterectomy is made by a medical professional based on a patient's individual health status and the severity of their arterial disease.
