In some cases, a contrast dye is employed to assist the doctor in visualizing the surgical site. Laser atherectomy may be performed alone or in combination with an angioplasty. The procedure is usually performed under sedation and local anesthesia. Once the plaque is dissolved, the remaining traces are removed by the catheter or, if small enough, simply permitted to circulate through the blood stream. High-energy laser light beams emitted through the catheter are aimed at the blockage and the plaque is vaporized. These may include:ĭuring a laser atherectomy, a thin catheter is inserted and moved through the artery to the site of the arterial blockage. Various instruments and tests can detect the presence of vascular disease. Discoloration or loss of hair on the legs or feet.Numbness or coldness of the legs or feet.Peripheral Vascular Disease most often affects the legs, but can also occur in the arteries leading to the arms, head or internal organs. While laser atherectomy is an innovative procedure with many benefits, it may not be appropriate for all patients with PAD. This procedure is particularly helpful in treating arterial blockages in smaller branches of blood vessels. Laser atherectomy is a minimally invasive procedure designed to allow the damaged blood vessel to dilate, increasing blood flow and providing for the necessary oxygenation of the tissues involved. During a laser atherectomy, a laser beam is employed to vaporize the offending debris. Previously, atherectomy was performed using a sharp blade to remove plaque from a blood vessel. Arterial plaque, made up of cholesterol and other substances, usually forms in arteries already narrowed and hardened by the process of arteriosclerosis, a normal part of aging. PAD most frequently occurs in the legs but can occur elsewhere in the body. Peripheral artery disease or PAD, also known as peripheral vascular disease or PVD, is caused by atherosclerosis, a condition in which the arteries become clogged with plaque and blood flow is impeded. Laser atherectomy is a new and efficient method of removing plaque from blood vessels clogged by peripheral artery disease.
