| Abstract | 「要旨」 前下行枝起始部病変は, 頻度が高く致命率の高い病態で, また冠動脈造影上, 高位側壁枝病変との分離が必要なので, 前下行枝起始部病変 (15例) または高位側壁枝病変 (5例) によって運動負荷Tl-201心筋SPECT像に生じた虚血領域の特徴を検討した. 心基部短軸断層像の虚血領域をプロフィールカーブで求め, 位置は12時を0度とし, 時計方向にプラスとして表示した. 前下行枝起始部病変による虚血領域の幅は, 角度で168±34度, 虚血領域の右縁は20±6度で, 20〜60度の間に67% (10/15) が属した. 左縁は-146±40度であった. 高位側壁枝による虚血領域の幅は, 角度で64±10度で, 右縁は78±10度, 左縁は14±10度に位置した. SEPCT心基部短軸像に生じた前下行枝起始部病変による虚血領域右縁と高位側壁枝による虚血領域右縁の重なりを認めなかった. 左縁でも同様であった. 心筋SPECT像により, 前下行枝起始部病変と高位側壁枝病変の分離同定が可能と考えられた. |

| Abstract | [Summary] Noninvasive detection of coronary artery lesion of just proxymal portion of left anterior descending artery (LAD) is important because of its high morbidity. It is angiographically difficult to distinguish LAD and high lateral branch (HL) . Utility of stress Tl-201 myocardial SPECT images for this purpose characteristics of ischemic region induced by coronary artery lesion of just proxymal portion or LAD or HL were studied in 15 patients with localized stenosis more than 75% at just proxymal portion of LAD and 5 patients with localized stenosis more than 75% at HL. Width of ischemic region at basal plane of SPECT images was determined by circumferential maximum count profile analysis of stress Tl-201 myocardial images. Width of ischemic region induced by coronary artery lesion of just proxymal portion of LAD was 168+-34°. Right margin of ischemic region was 20+-6° and in 10 of 15 patients right margin lay between 20° and 60° . Left margin was -146+-40° and 7 patients with left margin more than -150° showed left dominant coronary artery. Width of ischemic region induced by coronary lesion of HL was 64+-10° . Right margin of ischemic region was 78+-10° and left margin was 14+-10° . These results showed the possibility of detecting cornary artery lesion of just proxymal portion of LAD and lesion of HL by stress Tl-201 myocardial SPECT images. |
