Improve the Narrowed Artery
Which opens narrowed arteries, is a procedure performed by interventional cardiologists using a long, thin tube called a catheter carrying a balloon (or balloon) at the end, they inflate in place obstruction of the artery to compress the plaque against the artery wall. Angioplasty is also called percutaneous transluminal coronary angioplasty (PTCA). The procedure involves threading a thin wire (guide catheter) into an artery in the leg and is guided to the narrowed area of the coronary artery. The catheter with the balloon passed over the guide catheter and is located at the site of the blockage, where the balloon is inflated. After treatment, the guide catheter is withdrawn and the catheter with a balloon. The hospital stay and recovery time for this procedure are less than a bypass. But about 35% of patients run the risk of blockages in the treated area (which is called restenosis). Restenosis usually occurs within six months following the completion of the procedure.
Balloon angioplasty is complemented by the placement of a stent. A stent is a device made of metal mesh that is implanted in the area of the artery narrowed by plaque. The stent is mounted on a catheter with a balloon at the tip, is inserted through the artery and is located at the site of obstruction. Then the balloon is inflated, which causes the stent. Then removed the catheter and deflated balloon, leaving the stent in place. Restenosis rates with this procedure is typically between 15 to 20 percent.
Balloon angioplasty is complemented by placing a stent. Restenosis is a problem with the stenting procedure, doctors have been trying to find ways to prop open arteries in which stents were placed. Some newer stents are coated with medicines that reduce the likelihood that the artery from closing again. These are called coated stents or “drug-eluting stents”
