| Outline of Final Research Achievements |
The indocyanine green angiography has been applied for cardiovascular surgery. We aimed to investigate the quantitative assessment of bypass graft during coronary artery surgery in this study. We showed the usability of “intensity measurement procedure” to evaluate the blood flow through the bypass graft. It was suggested that the decrease of ICG intensity of bypass graft reflected the anastomotic stenosis. And, ICG angiography revealed the decrease of blood perfusion in the intestine by abdominal aorta or iliac artery clamp although its decrease rate depends on patients. Therefore, it was suggested the utility of the qualitative evaluation procedure of the peripheral perfusion of intestine. The quantitative procedure of peripheral perfusion of intestine by ICG angiography needs further research by experimental and clinical study.
