| Abstract | 「要旨」脳血管障害慢性期における123I-IMP SPECT像上の集積低下域(low accumulation area以下LAA)とX線CT像上の低吸収域(low density area以下LDA)に大きな乖離を認めた症例について検討した. 123I-IMP SPECT像あるいはX線CT像で異常を認めた76例中19例でLAAがLDAに比べ, 血管領域を超えて広範囲に認められた. この乖離のある群では59%で主幹動脈の閉塞または狭窄を認めたのに比べ, LAAとLDAが一致した群では7%のみであった. 乖離の主な原因として主幹動脈の病変にもとづく皮質領域の血流低下が考えられたが, 神経伝達路の障害によるremote effectの推定される症例もみられた. また乖離のある群では, ない群に比べてX線CT像上では所見のない高次機能障害を示唆する神経学的所見が多く, これらは主幹動脈病変による広範囲の血流低下に起因するものと考えられ, 血管造影所見とも一致した. |

| Abstract | [Summary]The discrepancy between the low accumulation area (LAA) seen on 123I-IMP SPECT and the low density area (LDA) on X-ray CT was evaluated in 76 cases with chronic cerebrovascular disease. In 19 patients, LAA was larger than LDA beyond the vascular territory. Brain angiogram showed either obstruction or stenosis of the major arteries in as many as 59 percentages of this discrepancy group. In many patients of this group, cortical neurological symptoms were observed. In 37 patients in which the size of LAA was equal to that of LDA, abnormality of the major arteries was observed in only 7 percentages. These results indicated that the discrepancy mainly reflected the infarction due to irreversible ischemic change of perforate artery with the cortical low perfusion caused by the major artery disease. In some patients, the dicrepancy was believed to show the remote effect caused by neurological pathway disturbance. |
