Excimer laser angioplasty is a minimally invasive medical procedure used to treat blockages in blood vessels, particularly in the coronary arteries. It involves the use of an excimer laser, which is a high-energy, ultraviolet laser that emits short pulses of light.
During the procedure, a thin, flexible tube called a catheter is inserted into a blood vessel through a small incision, usually in the groin. The catheter is carefully guided through the blood vessels using imaging techniques such as fluoroscopy and angiography. Once the catheter reaches the site of the blockage, the excimer laser is activated.
The excimer laser emits light at a specific wavelength that is absorbed by the plaque, a fatty substance that forms on the inner walls of the blood vessels. The laser's energy vaporizes the plaque without damaging the surrounding healthy tissue. This process is known as ablation.
By removing the plaque, the excimer laser angioplasty procedure widens the narrowed blood vessel, allowing for improved blood flow to the heart. This can help relieve symptoms of chest pain (angina) and reduce the risk of a heart attack.
Excimer laser angioplasty is considered a promising alternative to traditional angioplasty techniques, such as balloon angioplasty or stenting. It has been found to be effective in treating complex blockages and in cases where other treatment options have failed. However, like any medical procedure, it carries certain risks and may not be suitable for all patients. It is important to consult with a healthcare provider to determine the appropriate treatment approach for individual cases.
