Type of Surgery
Last updated: 11/24/2009
Angioplasty is a term describing a procedure used to widen vessels narrowed by stenoses or occlusions. There are various types of angioplasty. The specific names of these procedures are derived from the type of equipment used and the path of entry...
to the blood vessel. For example, percutaneous transluminal angioplasty (PTA) means that the vessel is entered through the skin (percutaneous) and that the catheter is moved into the blood vessel of interest through the same vessel or one that communicates with it (transluminal). In the case of an angioplasty involving the coronary arteries, the point of entry might be the femoral artery in the groin, with the catheter/guidewire system passed through the aorta to the heart and the origin of the coronary arteries at the base of the aorta just outside the aortic valve.
Sometimes used interchangeably, coronary angioplasty and stenting are actually two separate procedures. This video shows how coronary angioplasty and stenting are performed and how the two procedures differ.
Angioplasty is the technique of mechanically widening a narrowed or obstructed blood vessel; typically as a result of atherosclerosis. Tightly folded balloons are passed into the narrowed locations and then inflated to a fixed size using water pressures some 75 to 500 times normal blood pressure (6 to 20 atmospheres).
The word is composed of the medical combining forms of the Greek words Î±Î³Î³ÎµÎ¹Î¿Ï‚ aggeÃ®os meaning "vessel" and Ï€Î»Î±ÏƒÏ„ÏŒÏ‚ plastÃ³s meaning "formed" or "moulded". Angioplasty has come to include all manner of vascular interventions typically performed in a minimally invasive or percutaneous method.
How many open-heart surgeries are performed each year? In 2005 in the United States, these procedures were performed: Valve replacements 106,000 Bypass (cardiac revascularization) 469,000 Heart transplants (performed in 2006) 2,192 Total open-heart procedures 699,000.
