| Abstract | 「要旨」冠動脈バイパス術(CABG)後の201Tl負荷心筋SPECT所見と冠動脈造影によるバイパスグラフトの開存の有無を, グラフトに用いた血管の種類に着目して比較検討した. CABG術後1か月目に201Tl負荷心筋SPECTが施行された103名を対象とし, 解析を行った. 心筋全体を9つの領域に分け, それぞれの領域ごとに5段階の視覚的評価を行った. 開存グラフトにおいて, 201Tl負荷心筋SPECTにて再分布を伴う負荷時集積低下の認められた領域は動脈グラフトでは117領域中36領域(30.8%), 静脈グラフトでは133領域中11領域(8.27%)であり動脈グラフトで有意に高い値を示した(p<0.001). 以上より動脈グラフト静脈グラフトと比較して冠血流予備能が不十分な場合が多いことが示唆された. 201Tl負荷心筋SPECTはバイパス術後の冠血流予備能を評価する上でも有用な検査と考えられた. |

| Abstract | We performed stress 201Tl myocardial SPECT to evaluate ischemia and perfusion reserve after coronary artery bypass grafting (CABG). A total of 103 patients was performed stress 201Tl myocardial SPECT one month after CABG. Each patient's myocardium was divided into 9 segments and visually evaluated using five grade scoring system (0=defect, 1=severe decrease, 2=moderate decrease, 3=mild decrease, 4=normal uptake). Eleven of 133 (8.27%) segments covered by patent venous grafts showed reversible 201Tl defect, however, 36 of 117 (30.8%) segments which covered by patent arterial grafts showed reversible 201Tl defect. This finding was observed more significantly in arterial grafts than in venous grafts (p<0.001). These finding suggests that arterial grafts have lower flow capacity than venous grafts at peak exercise. |
