| Abstract | 「要旨」左前下行枝に単独病変を認め負荷201Tl心筋SPECT像に虚血が生じた53例を対象として, 心基部短軸断層像に生じた虚血域の右縁と前下行枝の狭窄部位との関係を検討した. 短軸像に生じた虚血域の位置は12時を0度として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域右縁は平均21±11度, 近位部病変による虚血域右縁は平均-6±10度, また中間部病変による虚血域右縁は平均-36±17度であった. 病変が起始部を離れるほど虚血域右縁は反時計方向に移動した. 虚血域右縁が0度以上であることは起始部病変に対してsensitivity 100%であった. 虚血域右縁が0度未満であることは中間部病変に対してsensitivity 100%であった. 201Tl心筋断層像により, 左前下行枝の病変の有無を推定できるだけでなく, 病変の部位も推定可能と考えられた. |

| Abstract | [Summary]Noninvasive estimation of site of lesion of left anterior descending artery (LAD) is important because of high morbidity of LAD lesion. Utility of stress 201Tl myocardial SPECT images for predicting site of LAD lesion characteristics of ischemic region induced by LAD lesion in the basal coronal image were studied in 53 patients with localized significant LAD lesion. Right margin of ischemic region at basal plane of SPECT images was determined by circumferential maximum count pofile analysis of stress 201Tl myocardial images. Right margin of ischemic region induced by the just proximal lesion was 21+-11°, that by proximal lesion was -6+-10° and that by mid portion was -36+-17°. Sensitivity of right margin of ischemic region 0 for just proximal lesion was 100% (20/20) and that of right margin of ischemic region 0 for mid portion lesion was 100% (18/18). These results showed the possibility of detecting site of LAD lesion by stress 201Tl myocardial SPECT images. |
