Supplemental balloon dilatation is performed in this channel to achieve an adequate internal luminal size. Directional atherectomy refers to a technique in which part of the blockage is mechanically shaved off and removed from inside the artery and then additional balloon angioplasty or stent angioplasty may be needed. Increasingly, thin metal coils are being used to expand the blocked arteries. The stent provides a mechanical scaffolding and prevents the possible complete blockage of the artery that may occur due to unexpected tear with balloon angioplasty. The use of stent angioplasty, when considered appropriate, improves the chances of success, both immediately and on a long-term basis.
Special blood thinning medications are necessary with stent angioplasty.
Also, a dental workup is not recommended for two to three months after stent angioplasty and, if it is necessary, precautionary antibiotics are advised. The stents do not interfere with metal detectors in airports. Avoidance of extensive surgery. Easy to repeat if necessary. Symptomatic relief with improvement in quality.
