Paper Abstract

This study compared carbon dioxide (CO2) gas and saline as an irrigation medium for angioscopy in the femoral and coronary artery of 6 dogs. All angioscopy procedures were performed percutaneously and antegrade and, in the femoral artery, with and without proximal balloon occlusion. With saline and carbon dioxide gas, successful peripheral angioscopy with proximal occlusion could be performed in five and six dogs, respectively. Without proximal occlusion no angioscopy procedure was successful with saline, whereas with carbon dioxide gas in four dogs successful angioscopic images could be obtained. No complications occurred after peripheral CO2 gas angioscopy. However, CO2 gas angioscopy in the coronary arteries was lethal in all animals.
