A spinal angiogram (digital subtraction angiogram) is a medical imaging procedure that involves injecting a contrast dye into the spinal arteries to obtain detailed images of the blood vessels that supply the spinal cord. It is usually performed to diagnose and treat spinal cord conditions such as arteriovenous malformations (AVMs), arteriovenous shunts and spinal cord tumours.
During the procedure, a small catheter is inserted into an artery in the groin area and guided to the spinal arteries using X-ray guidance. Contrast dye is then injected into the catheter to make the spinal arteries visible on X-ray images. The procedure usually takes about 1 to 2 hours.
Overall, a spinal angiogram is a safe and effective procedure for diagnosing and treating spinal cord conditions.
