An angiogram is a medical procedure that uses a catheter and dye to view blood flow in specific arteries or veins. It can detect blockages or bulges and is commonly used for heart, lung, or brain vessels. Patients must fast and may need to stop certain medications before the procedure. Afterward, they must avoid physical activity and consume plenty of fluids.
An angiogram is a type of medical procedure that allows doctors to see blood flow in a specific artery or vein. The most common use of an angiogram is to look at blood vessels in the heart, lungs, or brain, although this procedure can be used for other blood vessels as well. A small catheter is inserted into a blood vessel and a specialized dye is injected into the blood vessel. An x-ray is then taken so the doctor can clearly see the flow of blood through the vessel. The procedure can detect several problems in the blood vessel, including bulges or blockages, so that proper treatment can begin.
The patient is typically asked not to eat or drink anything for several hours before the procedure. Some medications, such as aspirin, may also need to be stopped before the angiogram. This procedure is usually done on an outpatient basis, although some doctors prefer an overnight stay in the hospital in case complications arise.
Before the angiogram begins, a small catheter known as an IV is inserted into a vein so that any necessary medications or fluids can be delivered directly into the bloodstream. A local anesthetic is then used to numb the area where the procedure will be performed. A small puncture is then made in the skin so the doctor can access the blood vessel being tested.
A small catheter is inserted into the blood vessel and a special type of iodine-containing dye is injected into the vessel. An X-ray machine is then used to take several pictures of the vessel so the doctor can assess blood flow in the vessel. After the procedure is complete, the catheter is removed and firm pressure is applied to the test site for several minutes until the bleeding stops.
After the angiogram, the patient will need to avoid physical activity for a couple of days to prevent the site from bleeding. To prevent dehydration and to help flush the dye from your body, you should consume plenty of fluids for a few days after the procedure. The medical staff will give the patient detailed instructions on activity limitations and any medications that may be needed based on the angiogram results. Any questions or concerns about the procedure or recovery period should be discussed with a doctor or other medical professional.
