angiografioissa

Angiografia, also known as an arteriogram or venogram, is a medical imaging technique used to visualize the blood vessels of the body. It involves injecting a contrast dye into the bloodstream, which then highlights the vessels on X-ray images. This allows doctors to examine the structure and flow of blood within arteries and veins, helping to detect abnormalities such as blockages, narrowing, aneurysms, or malformations.

The procedure typically begins with the insertion of a thin, flexible tube called a catheter into a blood vessel, often in the groin or arm. This catheter is then guided to the specific area of interest under X-ray guidance. Once in place, the contrast dye is injected through the catheter, and a series of X-ray images are taken. The contrast dye appears white on the X-ray, making the blood vessels clearly visible against the surrounding tissues.

Angiography is a valuable diagnostic tool used in various medical fields, including cardiology, neurology, and radiology. It can help diagnose and assess conditions like coronary artery disease, stroke, peripheral artery disease, and tumors. In some cases, angiography can also be used therapeutically, a process known as interventional radiology. This can involve procedures like angioplasty to open blocked vessels or embolization to stop bleeding. While generally safe, the procedure carries some risks, including allergic reactions to the contrast dye, bleeding at the catheter insertion site, or damage to the blood vessel.
