An angiogram is a procedure that enables the physician to visualize blood vessels by x-ray. For the blood vessels to be visualized, they need to be filled with contrast material (x-ray dye). A catheter delivers the contrast to the particular blood vessels the physician wants to see and shows us a map of the vessels in the area.
The intentional closing of blood vessels – can be used in the treatment of many conditions. Sometimes embolization can be the sole form of treatment, but it can also be used in conjunction with surgery. An embolizing agent – a material used to seal the blood vessel – is injected through the catheter. There are a variety of embolic agents used depending on the specific requirements. They include: small plastic particles, glue, or foam; each has a specific use depending on the vascular disorder being treated.
