Stent Implantation Coronary Angioplasty – PreOp Patient Education HD


Your doctor has recommended that you undergo
a balloon angioplasty with a stent implant. But what does that actually mean? The heart is located in the center of the
chest. It’s job is to keep blood continually circulating throughout the body. The blood vessels that supply the body with
oxygen-rich blood are called arteries. The arteries that supplies blood to the heart
muscle itself are called coronary arteries. Sometimes, these blood vessels can narrow
or become blocked by plaque deposits, restricting normal blood flow. In simple terms, a balloon angioplasty with
stent insertion is a procedure used to increase the amount of blood flowing through the coronary
artery. During a balloon angioplasty, a heart specialist
will insert a thin tube into an artery in your arm or leg and gently guide it towards
the problem area in your heart. Once the tube is in place, a small balloon
is briefly inflated in order to widen the narrowed artery. A short length of mesh tubing called a stent
is then inserted into the newly widened artery. During and after the procedure, your doctor
will take x-rays in order to monitor your progress. On the day of your operation, you will be
asked to put on a surgical gown. You may receive a sedative by mouth and an
intravenous line may be put in. You will then be transferred to the operating
table. To begin, your leg and groin are swabbed with
an antiseptic solution. Then the doctor will make a small cut over
the femoral artery in the upper part of the leg. A special needle is then inserted into the
artery itself. Then a guide wire is carefully passed through
the needle and gently pushed into the artery and upwards towards your chest. A narrow tube, called a catheter is threaded
along the wire until it too has reached the coronary artery. Next, the doctor uses the catheter to inject
a dye into the artery itself. The die shows up on a TV monitor and is used to pinpoint
the exact location of the blocked area. Once the restricted area has been identified,
a thin wire is inserted into the catheter, and is guided all the way to the blocked area
and then slightly beyond. This wire acts as guide for the balloon catheter.
It allows your doctor to position the deflated balloon precisely in the middle of the narrowest
part of the coronary artery. The balloon is briefly inflated. As it expands,
it squeezes the plaque deposits against the wall of the artery. It also stretches the
artery wall and enlarges the channel through which blood flows. Your doctor will continue to inflate and deflate
the balloon until normal blood flow has been restored. The balloon catheter is then withdrawn and
another balloon catheter is inserted. This balloon has the mesh stent tube wrapped around
it. Once this tube has been placed in the center
of now widened area of the artery, the balloon is briefly inflated. The stent expands until
it hugs the walls of the artery. Finally, after a thorough investigation of
the region, the catheters and guide wire are withdrawn and the stent remains permanently
to provide support to the artery and to resist the buildup of plaque. The dye that had been injected will break
up and leave your body as waste. Slight pressure is applied to the incision
in your leg in order to prevent bleeding.
