What is laser angioplasty?
Laser angioplasty is a minimally invasive procedure that uses laser energy to remove or vaporize plaque from the walls of blood vessels. It is primarily used to treat narrowed or blocked arteries caused by atherosclerosis, which is the buildup of fatty deposits or plaque inside the arteries.
How does laser angioplasty work?
Laser angioplasty involves the following steps:
- Catheter Insertion: A catheter with a laser device at its tip is inserted into a blood vessel, usually through a small incision in the groin or arm.
- Laser Application: The catheter is guided to the site of the blockage. The laser is then activated, emitting light energy to target and vaporize the plaque or break it into smaller fragments.
- Plaque Removal: The debris created by the laser is either absorbed by the body or cleared out by the catheter.
- Balloon Angioplasty (if needed): In some cases, a balloon may be inflated to further widen the artery after the plaque has been treated.
- Stent Placement (if needed): A stent may be inserted to keep the artery open.
What are the indications for laser angioplasty?
Laser angioplasty is typically indicated for:
- Atherosclerosis: Narrowing or blockage of arteries due to plaque buildup.
- Restenosis: Re-narrowing of an artery after a previous angioplasty.
- Complex Lesions: Plaques that are difficult to treat with traditional balloon angioplasty.
What are the advantages of laser angioplasty?
You might feel some pressure or mild discomfort when the balloon is inflated, but the procedure itself is usually not painful. Some people experience a warm sensation from the contrast dye.
Advantages of laser angioplasty include:
- Targeted Treatment: The laser can precisely remove plaque with minimal damage to surrounding tissue.
- Minimally Invasive: The procedure is less invasive compared to open surgery.
- Effective for Certain Lesions: It is particularly useful for treating complex or resistant plaques.
