This procedure usually takes about an hour. It might take longer if stents are inserted into more than one artery during the procedure.
Before the procedure starts, you'll get medicine to help you relax. You'll be on your back and awake during the procedure. This allows you to follow your doctor's instructions.
Your doctor will numb the area where the catheter will be inserted. You won't feel the doctor threading the catheter, balloon, or stent inside the artery. You may feel some pain when the balloon is expanded to push the stent into place.
Although this procedure takes only a few hours, it often requires a 2- to 3-day hospital stay.
Before the procedure, you'll be given medicine to help you relax. If your doctor is placing the stent in your abdominal aorta, you may receive medicine to numb your stomach area. However, you'll be awake during the procedure.
If your doctor is placing the stent in the chest portion of your aorta, you'll likely receive medicine to make you sleep during the procedure.
Once you're numb or asleep, your doctor will make a small cut in your groin (upper thigh). He or she will insert a catheter into the blood vessel through this cut.
Sometimes two cuts (one in the groin area of each leg) are needed to place fabric stents that come in two parts. You will not feel the doctor threading the catheter, balloon, or stent into the artery.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Stents, visit www.clinicaltrials.gov.

NIH study shows survival advantage for bypass surgery compared with non-surgical procedure
A new comparative effectiveness study found older adults with stable coronary heart disease (CHD) who underwent bypass surgery had better long-term survival rates than those who underwent a non-surgical procedure to improve blood flow to the heart muscle, also called revascularization.
The NHLBI updates Health Topics articles on a biennial cycle based on a thorough review of research findings and new literature. The articles also are updated as needed if important new research is published. The date on each Health Topics article reflects when the content was originally posted or last revised.
