Comparison of CO2 DSA and Conventional Angiography Using Non-ionic Contrast IVledia in Lower Extremity Angiography
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.
