What is DSA? (Digital Subtraction Angiography)

Digital Subtraction Angiography (DSA) is a medical imaging technique used to visualize blood vessels in a patient's body. It is a type of fluoroscopy that involves the use of contrast dye and X-rays to create detailed images of blood vessels.

During a DSA procedure, a contrast dye is injected into the patient's bloodstream. The dye is designed to absorb X-rays, making the blood vessels visible on the X-ray images. The X-ray images are then digitized and subtracted from a baseline image, which is taken before the dye is injected. This process eliminates the background structures and highlights only the blood vessels filled with contrast dye, resulting in a clearer image of the blood vessels.

DSA is commonly used to diagnose and evaluate a variety of vascular conditions such as aneurysms, stenosis, and arterial occlusions. It is often used in combination with other imaging techniques such as CT scans, MRI, and ultrasound to provide a comprehensive view of the patient's vascular system.

DSA is generally considered a safe procedure, but as with any medical procedure, there are potential risks and complications associated with it, such as allergic reactions to the contrast dye, bleeding, or infection. Patients should discuss these risks with their healthcare provider before undergoing the procedure.
