| Abstract | 「要旨」経皮的冠動脈拡張術 (PTCA) 施行時の一過性冠動脈閉塞時の心筋灌流像の撮像を3例に試みた. 2例では最終バルーン拡張時に経静脈的にタリウム-201 3 mCi (111MBq) を投与, 術直後に血管造影室内設置のポータブルガンマカメラにて3方向よりプラナー像を, 1例ではSPECT像を得た. 一過性冠動脈閉塞時には閉塞血管に応じた心筋灌流欠損像を示し, 3時間後には再分布したが, 側副血行路の明確な1例では灌流欠損は軽度であった. 本法はPTCAの手技, 患者の安全性に影響することなく, ヒトにおける一過性冠動脈閉塞時の心筋灌流状態の把握を行い得る有用な方法である. |

| Abstract | [Summary] To evaluate the myocardial perfusion during transient coronary occlusion, we attempted to obtain the myocardial scintigraphy during percutaneous transluminal coronary angioplasty (PTCA) . Tl-201 was injected at the last inflation of angioplastic balloon and occlusion was kept on for 60 sec. Planar images or SPECT were obtained immediately after PTCA. With this protocol, myocardial perfusion defects were observed during PTCA and fully redistributed 3 hours after Tl injection. Extent of ischemic lesions were almost same as that observed during exercise in two cases without collateral vessels. In a case with well visualized collateral vessels, perfusion defect was smaller in PTCA images than that in exercise stressed images. We conclude that intravenous injection of Tl-201 during PTCA is useful to assess the alteration of myocardial perfusion due to transient coronary occlusion without increasing the risk of angioplastic procedure. |
