Angiografien

Angiografien is a medical imaging technique used to visualize blood vessels. It involves the injection of a contrast agent, a special dye that is visible on X-rays, into the bloodstream. This contrast agent travels through the arteries and veins, allowing them to be seen clearly on specialized X-ray equipment.

The procedure typically begins with a small incision, usually in the groin or arm, to access an artery. A thin, flexible tube called a catheter is then inserted and guided through the blood vessels to the area of interest. Once the catheter is in place, the contrast agent is injected. X-ray images are taken rapidly as the contrast agent flows through the vessels.

Angiografien is used for a variety of diagnostic and therapeutic purposes. It can help identify blockages, narrowing, or abnormalities in blood vessels, such as those caused by atherosclerosis, aneurysms, or tumors. In addition to diagnosis, angiography can also be used to treat certain conditions. For example, angioplasty, a procedure to open blocked arteries, and stenting, where a small mesh tube is placed to keep an artery open, are often performed during an angiogram.

The procedure is generally considered safe, but potential risks include allergic reactions to the contrast agent, bleeding or bruising at the catheter insertion site, and damage to blood vessels. The duration of the procedure varies depending on the area being examined and whether any interventions are performed. Recovery time is usually short, with patients often able to resume normal activities within a day or two.
