Abstract「要旨」虚血性心疾患14例の冠動脈バイパス術前後に13N-アンモニアおよび18FDGを用いたポジトロンCT検査を施行し, 術前に血流低下した領域で18FDG集積の有無より術後の組織血流・壁運動の改善の予測を行った. 術後血流の改善したのは術前の18FDG (+) の64%, 18FDG (-) の31%であった (P<0.05) . 一方壁運動の改善したのは術前18FDG (+) の78%, 18FDG (-) の20%であった (P<0.002) . 術前18FDG (+) であった14区域のうち, 術後18FDG集積の消失したのは7区域 (50%) であった. この領域の大部分は血流も壁運動も改善した (おのおの86%, 100%) のに対し, 18FDG集積の残存した領域ではあまり改善が期待できなかった (おのおの43%, 60%) . 以上より術前の18FDG集積の有無から術後の組織血流と壁運動の改善の予測が可能と考えられた. また18FDGの集積はバイパス術後でも必ずしも消失せず, その推移は心筋障害の程度の経時的変化を反映する点で有用と考えられた.

Abstract[Summary] Positron emission tomography using 13N-ammonia and 18F-fluorodeoxyglucose (18FDG) was performed before and after coronary bypass surgery in 14 patients with coronary artery disease. The predictive values of preoperative uptake of 18FDG in the hypoperfused segments were assessed for postoperative improvement in regional perfusion and wall motion. An improvement in regional perfusion was observed more often in the segments with an increase in 18FDG uptake (64%) than those with no increase in its uptake (31%) (p<0.05) . An improvement in regional wall motion was observed more often in those with an increased 18FDG uptake (78%) than those with no increased uptake (20%) (p<0.002) . Furthermore, among 14 segments with an increased 18FDG uptake preoperatively, 7 segments (50%) showed a decrease in uptake postoperatively. These segments tend to improve in regional perfusion (86%) and wall motion (100%) , as compared to those with similar 18FDG uptake (43% and 60%, respectively) postoperatively. These data suggest that preoperative uptake of 18FDG may be valuable for predicting improvement in regional perfusion and wall motion by coronary bypass surgery. An increased 18FDG uptake may often remain after the surgery, which is considered to reflect tissue damage in the ischemic myocardium.
