Angiogram
An angiogram is an X-ray procedure that can be both diagnostic and therapeutic. It is considered the gold standard for evaluating blockages in the arterial system.
An angiogram detects blockages using X-rays taken during the injection of a contrast agent (iodine dye). The procedure provides information that helps your doctor determine your best treatment options.
Angiograms are typically performed while you are sedated. The procedure may last 15-20 minutes or up to several hours, depending on how difficult the test is and how much treatment is given.
An angiogram is commonly performed under sedation with the use of local anesthesia.
- The procedure typically begins with a needle inserted into the femoral (groin) artery. From one treatment site, areas all over the body can be treated.
- From the insertion site, catheters (thin tubes) and wires are threaded through the arterial system to a specific area of interest or throughout the entire body.
- As the contrast agent is injected, X-ray images are taken, allowing your doctor to view the flow of the dye and identify any blockages. The surgeon can then choose the best mode of therapy for you — whether during or following the angiogram. This decision depends on your symptoms and the severity and characteristics of the blockages.
- Two common treatments that can be done during the angiogram are balloon angioplasty and stent placement.
Your doctor will specify how to prepare for your angiogram.
- You likely will need to stop eating and drinking six to eight hours before the procedure.
- Occasionally, you may need to stop taking certain medications.
- Angiograms (with or without balloon angioplasty/stenting) are considered outpatient procedures, and patients usually go home the same day.
- Because sedation is often used, you likely will not be able to drive yourself home. Be sure to arrange for transportation home after the procedure.
- Once home, you should avoid heavy lifting, stooping or bending for two days to reduce the risk of bleeding at the arterial puncture site. Most other activities can be resumed.
