An angiogram is an imaging procedure that enables physicians to view blood vessels of the body through the use of x-rays. This test is usually performed to examine blocked, narrow, enlarged arteries or veins in various parts of the body. Arteries and veins in the areas of the heart, abdomen, legs and brain can be studied through this procedure.
In order to create the x-ray images, a liquid called a dye, is injected through a flexible thin tube known as a catheter. The catheter is threaded through the artery or vein that needs to be studied. The point of insertion is usually the groin or arm. The dye is a contrast medium that enables visibility of the blood flowing within the blood vessels. The dye is then eliminated from the body through the kidneys and urine. An angiogram may be recommended to diagnose various vascular conditions such as obstruction in the arteries outside the heart, enlarged arteries, problems in the arteries of the kidneys, malformations of the arteries and complications of the veins. It is also possible for the doctor to treat a condition during an angiogram. This can be done in case of blood clots that have been detected during the procedure. An angioplasty or stenting procedure may also be preformed to clear blockages from arteries during the test. This will depend on the area and extent of the blockage. An angiogram begins with the insertion of a thin wire through a puncture made in the groin or arm. A catheter is then threaded over the wire and is guided to the area that needs to be studied. Once it is positioned properly, the dye is injected. X-ray images are taken as the dye moves through the blood vessel. Once the test is complete, the catheter is taken out and pressure is applied to the puncture site to stop the bleeding.
The individual is monitored for a few hours after the Angiogram procedure and the results of the test are discussed with him. Rest is necessary following this test and consumption of plenty of fluids is important so that the dye is flushed out of the body through the urine. Possible complications arising from this procedure include excessive bleeding or infection in the area of the puncture, allergic reaction to the contrast dye and problems in excreting dye which may occur in individuals with kidney disease. The average cost of a catheterization procedure ranges from $3000 to $6000.
