Long answer: This would be a long answer. But basically dsa is performed in a suite with x-ray. A catheter is placed unto the artery usually from the groin. You will be sedated some. X-ray contrast is injected into artery in the area of the to be evaluated. The x-ray will take a movie of the contract in the artery as it moves. At the end the catheter will be removed and pressure held till the bleeding stops.
