Angiography is a minimally invasive medical test that helps physicians diagnose and treat medical conditions. In Catheter Angiography, a thin plastic tube, called a catheter is inserted into an artery through a small incision in the skin. Once the catheter is guided to the area being examined for example the arteries of the heart, a contrast media is injected through the tube and images are captured using a small dose of ionizing radiation.
A small amount of blood will be drawn before starting the procedure to make sure your kidneys are working and that your blood will clot normally. The area of the groin or arm where the catheter will be inserted is shaved, cleaned, and numbed with local anesthetic. The Cardiac interventionist will make a small incision (only a few millimeters) in the skin where the catheter can be inserted into an artery. The catheter is then guided through the arteries to the area to be examined. After the catheter is removed and the incision site is closed by placing pressure on the area for about 10-20 minutes.
BENEFITS:
- Angiography may eliminate the need for surgery
- If surgery is necessary it can be performed accurately
- Angiography presents very detailed, clear and accurate pictures of the heart vessels.
- Unlike computed tomography (CT) or magnetic resonance (MRI), angiography makes it possible to combine diagnosis and treatment in a single procedure in the case of a stent to be placed in an area of severe arterial narrowing.
ANGIOPLASTY & STENT PROCEDURE
Angioplasty is a procedure to open narrowed or blocked blood vessels that supply blood to the heart. These blood vessels are called the coronary arteries.
A coronary artery stent is a small mesh tube that expands inside a coronary artery. It helps prevent the artery from closing up again. A drug eluting stent has medicine in it that helps prevent closing of the artery.
When a blockage is detected from the angiography procedure a guide wire is moved into and across the blockage. A balloon catheter is pushed over guide wire and into the blockage. The balloon on the end is blown up (inflated). This opens the blocked vessel and restores proper blood flow to the heart.
A stent (wire mesh tube) may then be placed in this blocked area. The stent is inserted along with the balloon catheter. It expands when the balloon is inflated. The stent is then left there to keep the artery open.
