Abstract： 目的探讨皮质下梗死所致半侧空间忽略与脑血流改变部位、范围及程度间的关系.方法对30例临床确诊为单侧皮质下梗死的右利手患者行SPECT局部脑血流(rCBF)显像,判定rCBF改变的部位、范围及程度.结果经忽略组合试验证实有半侧空间忽略表现的21例皮质下梗死患者,SPECT显像示rCBF降低部位多累及大脑皮质功能区(x2=7.91,P＜0.005).最多见于额叶,其次是顶叶、颞叶和枕叶.最明显的部位是颞顶枕交界处.病灶区rCBF及rCBF降低百分比与忽略评分的r分别为-0.44和0.31.病灶的范围、数量与忽略程度间呈显著正相关(r分别为0.74和0.72).结论皮层下梗死所致忽略多累及皮质功能区.多部位联合损伤易出现忽略且程度更严重.
