Carbon dioxide (CO2) is a colorless, odorless gas which occurs naturally in the
atmosphere and human body. With the advent of digital subtraction angiography,
the gas has been used as a safe and useful alternative contrast agent in both
arteriography and venography. Because of its lack of renal toxicity and allergic
potential, CO2 is a preferred contrast agent in patients with renal failure or
contrast allergy, and particularly in patients who require large volumes of
contrast medium for complex endovascular procedures. Understanding of the unique
physical properties of CO2 (high solubility, low viscosity, buoyancy, and
compressibility) is essential in obtaining a successful CO2 angiogram and in
guiding endovascular intervention. Unlike iodinated contrast material, CO2
displaces the blood and produces a negative contrast for digital subtraction
imaging. Indications for use of CO2 as a contrast agent include: aortography and
runoff, detection of bleeding, renal transplant arteriography, portal vein
visualization with wedged hepatic venous injection, venography, arterial and
venous interventions, and endovascular aneurysm repair. CO2 should not be used in
the thoracic aorta, the coronary artery, and cerebral circulation. Exploitation
of CO2 properties, avoidance of air contamination and facile catheterization
technique are important to the safe and effective performance of CO2 angiography
and CO2-guided endovascular intervention.
