Abstract

Aims and background: The aim of this work is to demonstrate the usefulness of carbon dioxide, used as contrast agent, in special indications in vascular interventional oncological procedures. Methods: We studied 40 patients with digital subtraction angiography enhanced with CO2 as a contrast agent. At the same time we utilized also, in all cases, jodinated contrast agent to evaluate the different opacification gradient, the different viscosity range and the different perfusion. Results: The low viscosity of CO2 allows demonstration of the presence of even minimal blood losses in gastrointestinal tumors and enhances arteriovenous shunts in hepatocellular carcinoma. Carbon dioxide can also be employed to assess the patency of small-sized catheters for chemotherapy infusion which do not allow easy injection of the traditional iodinated contrast agents characterized by high viscosity. Conclusion: Carboangiographic study combined to digital subtraction angiography can clear some diagnostic problems and is further method to assess the outcome of angiographic interventional procedures in oncology.
