Abstract:
PURPOSE: The purpose of this study is to compare CO2 DSA and nonionic contrast media angiography in respect to the quality of the opacification of collaterals and incidence of side-effects in peripheral occlusive arterial disease. MATERIALS AND METHODS: Sixteen patients who were suspected to have peripheral occlusive arterial disease were performed angiography with nonionic contrast media and CO2 at the same location with the same catheter. The causes of the lesions were atherosclerosis(n=7) and Buerger's disease(n:9). CO2 DSA was compared with nonionic contrast media angiography in respect to the quality of image in the diagnosis of the lesions, opacifications of collaterals and side-effects. RESULTS: In atherosclerosis;quality of the images of CO2 DSA was same as that of nonionic contrast media angiography in 6 patients and was poor in 1 patient;opacifications of collaterals of CO2 DSA were same as that of nonionic contrast media angiography in 5 patients and was poor in 2 patients. In Buerger's disease;quality of the images of CO2 DSA was same as that of nonionic contrast media angiography in 2 patients and was poor in 7 patients;opacifications of collaterals of CO2 DSA were same as that of nonionic contrast media angiography in 1 patient and was poor in 8 patients. Leg pain was the only side-effect after CO2 injection occuring in 4 out of 16 patients. CONCLUSION: CO2 could be used as safe contrast media in patient with risk factors for nonionic contrast media and for diagnosis of the atherosclerosis in lower extremity. For the procedures such as vascular intervention reguiring large amount of contrast media CO2 could effectively replace nonionic contrast media.
