DSA Digital Subtraction Angiography

Istanbul

Medically reviewed by Dr. Mahir Turan, MD · Last reviewed March 4, 2026

DSA Digital Subtraction Angiography in Istanbul is available at 4 hospitals in the Voumed network.

Digital subtraction angiography (DSA) is an advanced imaging method that shows the blood vessels throughout the body in fine detail. A thin catheter delivers a contrast agent into the arteries, and specialised computer processing strips away the surrounding bone and tissue so that only the vessels stand out sharply. It is used to detect vascular problems such as narrowing, aneurysm, malformation and abnormal connections in the brain, abdomen, skin and limbs. DSA is also the basis for many minimally invasive treatments, allowing a specialist to find and, in the same session, treat a vascular problem through a tiny entry point rather than open surgery.
