A diagnostic angiogram is a simple procedure to image the arteries and veins in the body. These images will help determine diseases causing narrowing or blockage of the vessels. They are performed as day case procedures which means the patient is safe to go home after the procedure.

The doctor will access the vessel with a small needle through which the procedure is performed. A contrast material (coloring material) is used to image the blood vessels for studying different diseases that might affect them.

Preparation for angiogram includes fasting, kidney function test to make sure it is normal or corrected if needed, coagulation profile.

After the procedure, usually, the patient has to stay flat for a few hours to prevent bleeding from the entry site. A small dressing applied at the end of the angiogram can be removed after 24 hours.

It is recommended to drink extra amounts of water for the next 24 hours to wash out the contrast material given during the procedure.
