基底节内囊区梗塞与构音障碍的探讨

基底节内囊区梗塞患者19例,经CT检查证实为基底节区梗塞16例,内囊区腔隙性梗塞3例,均为首次发病,其中急性发病者15例,亚急性发病者4例。临床表现均有轻微的语言障碍,即说话含糊不清,发音不准确,但均能完全被理解,复述相对好。19例中或伴有不同程度锥体束征,或分别伴有头晕、面部麻木、舌发麻或运动不灵活、口角流涎等。头颅CT检查病灶均位于皮层下,均为单发病灶。经治疗在1～2月恢复正常或基本正常。本文重点对基底节内囊区梗塞与构音障碍的机理和关系进行了讨论。

Discussion the Relationship Between Infarction of Internal Capsule of Basal Ganglion and Dysarthria

We have 19 cases with infarction of internal capsule of basal ganglion. Proved by CT, 16 cases were infarction of basal ganglion, the rest were lacunor infarction of internal capsule. All of them were attacked at the first time and the clinic phenomenon was similar. They all had slight linguistic obstacle, some with different degree pyramid sign and some with dizziness or facial numbness of lingua numbness or moving unnimbly or salivation. The result of CT showed that all foci which were solitary located in infracortial area. After having been treated, almost patients recoveied. The paper focuses on pathogenesis of dysarthria and relationship between infarction of internal capsule of basal ganglion and dysarthria.
