Carotid artery stenting is an endovascular procedure where a stent is deployed within the lumen of the carotid artery to treat narrowing of the carotid artery and decrease the risk of stroke. It is used to treat narrowing of the carotid artery in high-risk patients, when carotid endarterectomy is considered too risky.
Percutaneous coronary angioplasty is one of the most common procedures performed during U.S. hospital stays; it accounted for 3.6% of all operating room procedures performed in 2011. [38] Between 2001 and 2011, however, its volume decreased by 28%, from 773,900 operating procedures performed in 2001 to 560,500 procedures in 2011.
Various techniques of pain management and anesthesia are practiced during current PCI stent placement procedures. [7] The catheter/stent system is introduced into the body by penetrating a peripheral artery (an artery located in the arm or leg) and passed through the arterial system to deliver the DES into the blocked coronary artery.
Dr. Timothy Chuter pioneered this approach, with a completely endovascular solution. After partial deployment of the main body of an endograft, separate endograft limbs are deployed from the main body to each major aortic branch. This procedure is long, technically difficult, and currently only performed in a few centers.
The use of a coronary angioplasty to abort a myocardial infarction is preceded by a primary percutaneous coronary intervention. The goal of a prompt angioplasty is to open the artery as soon as possible, and preferably within 90 minutes of the patient presenting to the emergency room. This time is referred to as the door-to-balloon time.
During such procedures, a small incision is made in the groin area and a hole is created in the femoral artery to gain access to the artery. This hole is referred to as the access site or puncture site. At the completion of the procedure, the hole needs to be closed.

Stents, which are specially manufactured expandable stainless steel mesh tubes, mounted on a balloon catheter, are the most commonly used device beyond the balloon catheter. When the stent/balloon device is positioned within the stenosis, the balloon is inflated which, in turn, expands the stent and the artery.
