| Abstract | 「要旨」先天性左冠動脈肺動脈起始症(BWG症候群)の44歳女性に冠動脈バイパス術前後に201TlCl運動負荷心筋シンチグラムを施行した, 術前のSPECT, およびBull's eye像では前壁の一過性欠損像と後下壁の恒久欠損像を認めたが, 術後前壁, 後下壁ともに欠損像は消失した. 術前の前壁における欠損像は一過性虚血によると考えられる. しかし, 後下壁の恒久欠損像は術後消失したことより梗塞によるものではなく, 右冠動脈から左冠動脈へ大量の血流が短絡するために後下壁心筋の灌流障害が生じていたと考えられる. このように運動負荷心筋シンチグラムはBWG症候群の術前後における心筋灌流様式を明らかにするうえできわめて有用であった. 「I. 緒言」先天性左冠動脈肺動脈起始症(Bland-White-Garland症候群, 以下BWG症候群)の頻度は, 先天性心疾患の0.24%と, 比較的希な疾患で, 出生後早期に心筋虚血をきたし1歳未満で死亡することが多く, 成人例での報告は少ない. |

| Abstract | [Summary] Stress thallium-201 myocardial scintigraphy were performed in a 44-year-old female with BWG syndrome before and after aorto-coronary bypass surgery. Preoperative stress thallium-201 studies demonstrated anterior reversible perfusion defect and posterior persistent defect. But postoperative studies demonstrated no defects in both areas. These data suggest that preoperative anterior defect was due to transient myocardial ischemia, but the finding of posterior persistent defect wasn't due to infarction or scarring. Thus, stress thallium-201 myocardial imaging provided useful informations to clarify the myocardial perfusion patterns pre- and postoperatively. |
