摘要
目的:探讨经颅超声波多普勒方法在癫痫中的应用价值.方法:采用经颅超声波多普勒方法对6例不同类型发作中的癫痫患儿的大脑中动脉血流速度进行测定,并分析其与脑电改变的相关关系.结果:非典型失神发作时脑血流速度在脑电出现广泛性棘慢波后一过性下降,发作消失后0~8秒降至最低值,与发作前相比显著降低(P<0.01).非典型失神发作持续状态时脑血流速度显著降低,痉挛持续状态缓解后1~2周脑血流速度增加达正常范围.肌阵挛发作时脑血流速度在脑电出现多棘慢波后迅即上升,而后一过性下降.结论:上述结果提示,癫痫的发作型不同,脑血流速度改变亦不同,反映了发作机制的差异.
Objective: To explore the applied value of transcranial ultrasound Doppler抯 method in children withopilepsy .Method: The blood flow velosity of middle cerebral artery was measured in 6 patients at their attack stage with epilepsy of different types by transcranial ultrasound Doppler抯 method and the relations of the blood flow velosity to its related withelectroencephologram were analysised. Results: Cerebral blood flow velosity decreased transiently after EEG appeared diffusespike and wave on attacking of atypital absence seizures ,and fell to minimum during 0~8 seconds after attack wave disappeared (P<0.01). But it decreased strongly during epiepticism of atypical absence seizures, and returned to normal during one to twoweek after seizures have stopped. The cerebral blood flow velosity in paramyoclonus rose immediately after EEGappeared diffuse spike and wave.and then it dropped transiently. Conclusion: The results suggest that cerebral blood flow velosity is different ifparoxysm type of epilepsy is different, indicating different attack mechanisms.
