Angiografieën

Angiografieën is a medical imaging technique used to visualize blood vessels. It involves injecting a contrast agent, a dye that is visible on X-rays, into the bloodstream. This contrast agent travels through the arteries or veins, allowing doctors to see the structure and flow of blood within these vessels.

The procedure typically begins with a small incision, usually in the groin or arm, where a catheter, a thin flexible tube, is inserted into a major artery or vein. The catheter is then carefully guided to the area of the body being examined. Once in position, the contrast agent is injected through the catheter, and a series of X-ray images are taken. These images create a detailed map of the blood vessels, highlighting any blockages, narrowings, aneurysms, or other abnormalities.

Angiografieën are used for a variety of diagnostic and therapeutic purposes. Diagnostically, they help identify conditions such as atherosclerosis, which is the buildup of plaque in arteries, and deep vein thrombosis, a blood clot in a deep vein. Therapeutically, angiografieën can be used to treat certain conditions. For example, angioplasty, a procedure to widen narrowed arteries, and stenting, where a small mesh tube is inserted to keep an artery open, are often performed during an angiografie.

The procedure is generally safe, but like any medical intervention, it carries some risks. These can include allergic reactions to the contrast agent, bleeding at the insertion site, or damage to the blood vessel. Doctors carefully weigh these risks against the potential benefits before recommending an angiografie.
