Stents What to Expect When Getting a Stent
Having a stent placed is a minimally invasive procedure.
Coronary and carotid artery stenting
Procedures to place a stent to treat coronary and carotid arteries are similar. In both, your doctor will use cardiac catheterization to thread a thin tube with an empty balloon on the end through a blood vessel to the narrowed or blocked artery. Once in place, the balloon is filled with air and the stent is opened and placed in the artery.
- The procedure to place a coronary stent is called percutaneous coronary intervention (PCI), commonly known as coronary . Sometimes the procedure is done in an emergency, such as during a heart attack. The stent provides support to the artery after the artery is re-opened.
- The procedure to place a stent in the carotid artery is called carotid artery stenting. This is a minimally invasive treatment for severe carotid artery disease.
Aortic aneurysm stenting
After a cut is made in your upper thigh, your doctor inserts a stent graft through a large blood vessel using a catheter and guides it through the arteries to the location of the aortic aneurysm. The stent graft is placed at the site and opened up. Dye may be injected into the blood after the stent graft is placed to make sure it is working correctly and blood is not leaking into the aneurysm. The dye can be seen by X-ray.
An airway stent is placed using a bronchoscope, which is a small camera on the end of a long tube. The doctor slides the bronchoscope through your nose or mouth and then down through your throat into the trachea and the airways.
The stent is placed by sliding a guide wire along the side of the bronchoscope, then sliding a thin tube that carries the stent along the guide wire. Using the bronchoscope to watch, the doctor opens the stent in the narrowed airway. Fluoroscopy, a type of X-ray imaging, or ultrasound may also be used to help guide stent placement. After the stent is placed, your provider may check your lungs using a chest X-ray.
