What is Digital Subtraction Angiography (DSA)?
This examination is used to provide images of the lumen (inner surface) of the blood vessels including the arteries, veins, and the heart chambers. A prominent dye is injected to make the blood supply to the legs, heart or other organs visible. Complex computerised X-Ray machines are used to obtain these images.
Why Do You Need Digital Subtraction Angiography (DSA)?
This detailed technique is widely used to diagnose a spectrum of blood vessel diseases. It is recommended to get a check up and a proper diagnosis for obstructive vascular diseases that are caused by any blockages or narrowing in the lumen of arteries and veins.
It is possible that your doctor would request for a Digital Subtraction Angiography to diagnose a Brain aneurysm (specifically Intracranial Aneurysm), bleeding vessels, Arteriovenous malformations (abnormal connections between arteries and veins), and to examine the vascularity of cancerous tumours. Also, Angiography provides a visual guide for interventional procedures needed to unblock or re-open occluded arteries such as Angioplasty, Arterial Stent, Nephrostomy and Biliary Procedures.
