If during the venous consult, the doctor determines that blood flow is not optimal, additional diagnostic tests may be ordered to detect the location and/or severity of a blockage. These tests help the doctor decide which surgical procedure will be necessary to restore proper blood flow.
An angiogram is an outpatient procedure performed under light anesthesia to capture an image of the blood vessels. Because arteries are not normally visible by x-ray, a special dye and camera are used to highlight the vessels. The physician will insert a catheter in the upper thigh and guide it through the vessel all the way to the heart. Once in position, a special dye is injected. As the dye passes through the artery, an x-ray is taken to mark the flow of blood.
Intravascular Ultrasound (IVUS)
Using the intravascular ultrasound, our doctors can map the inside of your arteries. A small ultrasound device is attached to a catheter and guided through the femoral artery (in the groin area) to the area(s) of concern.
The CO2 angiogram is a useful diagnostic tool, especially for patients who have poor kidney function or sensitivity to the dye used in a traditional angiogram. In this technique, carbon dioxide is injected into the vessel instead of a dye.
