| Angiography Angiography is used to find problems or blockages in the arteries. A catheter is inserted through a small incision in the groin area. A physician guides the catheter to the area where the blockage is suspected. Next, dye is injected into the arteries while X-ray images are taken. The dye highlights the arteries, allowing the physician to accurately pinpoint the blockage. You will be asked to lie flat for six hours after angiography. If there is no bleeding or bruising at the catheter insertion site, you will be allowed to go home. You will probably be asked to return for angioplasty to repair the blockage. This is a process that involves surgically implanting a balloon or stent to re-open the blocked artery. |
