Repair of a narrowed blood vessel through surgery or other angiographic procedures.
A technique using a catheter with a balloon that can be inflated to expand an artery.
Plastic surgery to repair a blood vessel, e.g. a narrowed coronary artery.
Surgery done on arteries, veins, or capillaries; a technique in which a balloon is inflated inside a blood vessels to flatten any plaque (patch) that obstructs it and causes it to become narrowed (used to open coronary arteries).
Surgical intervention of diseased vessels for recanalization of a blood vessel; balloon dilation, mechanical stripping, injection of fibrinolytics, or placement of a stint.
A method of treating blockage or narrowing of a blood vessel by recanalising the vessel — that is, inserting a balloon into the constriction to reopen it. The technique is used to treat a narrowed artery in the heart or a limb. About 65 per cent of patients treated benefit, but when symptoms persist or recur the procedure may be repeated. There is a small risk of damage to the vessel or valve. New procedures under development include the use of lasers, cutting drills and suction to remove the deposits of atheroma blocking the arteries.
Any endovascular procedure that reopens narrowed blood vessels and restores forward blood flow. Most often angioplasties are performed on coronary, carotid, or peripheral arteries occluded by atherosclerosis. Some common angioplasty techniques include the following: atherectomy, which opens occluded, scarred, or calcified vessels by removing atherosclerotic plaques with rapidly rotating drills; balloon angioplasty, which uses the inflation of high pressure balloons within blocked arteries to force them open; laser and radiofrequency angioplasties, which vaporize or ablate atherosclerotic plaques; endovascular stents, which hold vessels open with expandable lattices inserted across the narrowed section of the artery.
A technique involving the utilization of a balloon catheter to mechanically expand the narrowed or constricted portion of a diseased artery, thereby enlarging the affected area.
