Angioplasty techniques. Computer illustration of balloon and laser angioplasty. Angioplasty is a surgical procedure to unblock and widen arteries that are narrowed or obstructed due to the formation of fatty plaques (atheroma),clots or scar tissue. A catheter (tube) is inserted into the artery. In the established technique (top),a balloon (beige) is inflated inside the affected area. The newer method (bottom) uses pulses of laser light (transmitted through a fibre optic) to destroy the blockage ahead of the catheter. This may be less traumatic to the arterial wall,decreasing the chance of narrowing recurring | |
