外伤性大脑镰旁血肿的诊断和治疗分析

目的探讨外伤性大脑镰旁血肿的发生机制、临床表现和治疗原则。方法回顾分析1995年以来收治的19例外伤性大脑镰旁血肿患者临床特点和治疗情况。结果治愈18例，1例因多脏器功能衰竭死亡。外伤性大脑镰旁血肿患者早期意识障碍不严重，其典型表现为对侧下肢单瘫或对侧偏瘫，下肢重于上肢。称为大脑镰综合征。结论头颅CT显示大脑纵裂池增粗的高密度影≥1cm及pseudodelta征，可作为诊断的参考标准。治疗以神经功能障碍或病情稳定与否来选择保守或手术治疗。

Diagnosis and treatment of traumatic interhemispheric subdural hematomas

Objective To explore the mechanism,clinical manifestation and treatment of traumatic interhemispheric subdural hematomas (ISH).Methods Clinical characteristics and management of 19 cases of traumatic ISH admitted since 1995 were retrospectively analyzed.Results 18 cases were cured and 1 died of multiple system organ failure.Because early-stage consciousness disturbance was not serious in traumatic ISH patients,it was characterized by hemiplegia or paralysis of the counterlateral lower limb known as falx syndrome.Conclusion It may be served as the diagnostic criteria for ISH.CT scan showed a thickness of hematocele over 1 cm and pseudodelta sign.Surgery or conservative management should be elected on the basis of functional disturbance and the stability of the disease.
