Does it hurt?
During the surgery, while you're under conscious sedation, you generally are able to tell your doctor if you're experiencing major pain. The place where your doctor inserted the wire will likely be sore after the procedure.
What are risk factors?
One of the most common problems with any surgery is bleeding. In rare circumstances, you can experience serious bleeding or develop a pseudoaneurysm, which occurs when an artery or the heart chamber is injured and causes blood to pool outside the artery's wall.
Some people are allergic the dye used during the procedure, which contains iodine. The amount of dye could affect your kidney function, but this isn't common.
Rare risk factors include a heart attack caused by the procedure, a stroke or the need for additional procedures. You should talk with your doctor about any concerns you have about the procedure.
What's recovery time?
Many people spend the night in the hospital and go home the next day. This isn't always the case. Some people are able to go home the same day, depending on how they're recovering after surgery. If you don't have other health issues, such as diabetes, you might not have to stay the night in the hospital.
If you had a significant blockage, you might start to feel better immediately.
What's the follow-up?
Your doctor will want to check in with you after your surgery and likely see you back a few times.
After the surgery, it is important to quit smoking, lose weight and take medicine your doctor prescribes, including blood pressure medicine and blood thinners. Listening to your doctor about taking your medications and making lifestyle changes is incredibly important after a stent procedure. Taking these actions decreases your risk for developing serious complications or needing another stent procedure.
