A tiny incision will be made in the groin to access an artery. A thin, hollow tube (catheter) will be placed in the artery. It will be threaded up to the site. A special dye is injected. It makes it easier to see on a video monitor. X-rays will help the doctor find the right place.
The blood vessel can be closed with:
Other man-made material
They are inserted though the catheter and to the site. Imaging tests will confirm the blood vessels are closed. The catheter will be removed. The incision will be closed and bandaged.
How Long Will It Take?
30 minutes to several hours—the time depends on what needs to be done
Will It Hurt?
Anesthesia will prevent pain during surgery. Medicines will ease pain after.
