Endovascular carotid stent placement is a procedure to open a
blocked carotid artery. There are two carotid arteries—one on each side of the
neck—that supply blood to the brain. Fatty buildup (plaque) can narrow or block
these arteries. When one or both of your carotid arteries are blocked, it can
make it hard for blood to flow to the brain. This procedure may improve blood
flow to your brain and lower your risk of having a stroke.
the procedure you will get medicine to prevent pain and help you relax. The
doctor will put a small tube, called a catheter, into a blood vessel in your
groin. He or she will move the catheter through the blood vessel to your
carotid artery. The doctor will put dye into the catheter. The dye will make
your carotid artery show up on X-ray pictures so the doctor can find the
blocked section of the artery.
The doctor will put a catheter with
a tiny balloon at the tip into your carotid artery. He or she will inflate the
balloon. This will stretch the narrowed part of the artery. The doctor will
take the balloon out.
Then the doctor will use the catheter to put
a small, wire-mesh tube (stent) into the carotid artery. The stent will hold
the artery open. The stent also may keep small pieces of plaque from breaking
off and causing problems. After the stent is in place, the doctor will take out
the catheter. The stent will stay in your artery.
usually takes about 1 to 2 hours. You may need to stay in the hospital for 1 or
2 days after the procedure.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all
appointments, and call your doctor if you are having problems. It's also a good
idea to know your test results and keep a list of the medicines you
procedure can be stressful. This information will help you understand what you
can expect and how to safely prepare for your procedure.
