Abstract

This article describes a series of patients where CO₂ used as a contrast agent identified extravasation and bleeding in patients in whom standard arteriography with contrast did not show the abnormality. The authors describe their series as well as the results in a group of 23 patients. This rather innovative method may be useful in selected patients in whom extravasating hemorrhage is suspected but not demonstrated on routine arteriography.
