Abstract | 「要旨」運動負荷201Tl心筋プラナーイメージにおける灌流欠損の局在部位および分布パターンより冠動脈狭窄部位を同定することを目的として, 170例の冠動脈疾患患者の運動負荷201Tl心筋プラナーイメージと冠動脈造影の所見を対比した. その結果, 左冠動脈前下行枝近位部(LAD proximal)のLAD6の病変では左冠動脈前下行枝遠位部(LAD distal)の病変に比べ前側壁領域と前壁中隔領域に灌流欠損を多く認めた. 特に高位前側壁領域に相当する部位の灌流欠損はLAD proximalの病変に比べLAD distalの病変ではきわめて少なかった. 前側壁領域の広範囲な灌流欠損のパターンあるいは, 前側壁領域および前壁中隔領域の両方にわたる広範囲な灌流欠損のパターンは, LAD proximal病変にきわめて特異的な所見と考えられ, 運動負荷201Tl心筋プラナーイメージングによりLAD proximal病変を予測しうる可能性が示唆された. 一方, 右冠動脈病変, 左冠動脈回旋枝病変では, 近位部病変に特有な灌流欠損の部位, 分布パターンは認められなかった. |

Abstract | [Summary]To determine the value of Tl-201 myocardial scintigraphic imaging (MSI) for identifying the locations of coronary artery narrowings, circumferential maximum count profile analysis of stress MSI was performed in 170 patients with arteriographically proved coronary artery disease. Perfusion defects located in the anterolateral wall in the anterior view and in the anterostal wall in the left anterior oblique view were found more frequently in patients with proximal disease in the left anterior descending (LAD) coronary artery than in patients with distal disease in the LAD. Especially, perfusion defects in the high anterolateral wall in the anterior view were more frequently associated with LAD proximal disease, compared to LAD distal disease. Perfusion patterns of extensive defect in the anterolateral wall or extensive defect both in the anterolateral wall and the anteroseptal wall were highly specific for proximal LAD disease. These results suggest the possibility of identification of proximal LAD disease by stress MSI. On the other hand, specific perfusion defect for proximal disease in the right coronary artery or left circumflex artery were not appreciated. |
