Outline of Final Research Achievements

In coronary artery bypass surgery, evaluation of the coronary arterial wall depends on surgeon's experience. These days, the pathology of coronary artery becomes more difficult based on the patients co-morbidity. Optical coherence tomography (OCT) is a light-based imaging modality that can be used to assess the structure of the arterial wall and the
characteristics of intraluminal plaques. In this study, we introduced this evaluation methods to the surgical field and assess the efficacy during coronary artery bypass surgery. We reported the result of the usefulness of the OCT in badly diseased coronary artery and also presented it in the international congress.

Academic Significance and Societal Importance of the Research Achievements

本研究によって、近年複雑化しつつある冠動脈病変において、より性状のよい吻合部位を選択することが可能となった。実臨床においてOCTを用いた血管評価が全例で必要であるわけではない。しかし数は少なくとも、OCTでの評価を必要とするような、非常に血管性状の悪い症例においてOCTを用いた評価を行い、至適吻合部位を決定できることはそのような症例の再入院・再治療といった予後を改善する可能性がある。また一度の手術で最適な治療ができることは医療費の削減にもつながると思われる。
