title: [Intraoperative graft assessment using fluorescent imaging system (SPY)].
abstract: We investigated the efficacy of intraoperative fluorescent imaging system for the assessment of coronary artery bypass grafting (CABG). We used SPY imaging system in 100 CABG (57 off-pump and 43 on-pump CABG), totalling 287 distal anastomoses. The total graft patency rate on postoperative angiography in this series was 96.2% (276/287). Graft revision was done in 10 cases (10.0%) and 13 anastomoses (4.5%) by SPY imaging, which all resulted in good patency at postoperative angiography. On the other hand, 7 distal anastomoses and 1 mammary graft (2.8%) appeared to be successful on intraoperative SPY imaging, but were revealed to be occluded by postoperative angiography. SPY imaging system is useful for graft validation, and may contribute to improvement of coronary bypass graft patency.
