Rasmussen脑炎患儿经颅多普勒超声检测结果的初步分析

Findings of Transcranial Doppler during Simple Partial Seizures with Rasmussen Encephalitis:8 Cases Report

目的初步分析Rasmussen脑炎患儿大脑中动脉(MCA)血流速度的变化。方法 Rasmussen脑炎确诊患儿8例,在单纯部分性癫痫发作的发作期和间歇期经颅多普勒超声(TCD)检测双侧MCA血流速度。结果病灶侧血流速度变化率与病灶对侧血流速度变化率的差值分析显示,平均血流速度的方差最小。TCD检测的双侧MCA在癫痫发作期表现为不均等的血流速度增加。结论平均血流速度较收缩期峰值血流速度、舒张期血流速度更适合作为评判指标。

Objective To analyze the blood flow velocities in middle cerebral artery with Rasmussen encephalitis. Methods8 patients with Rasmussen encephalitis were detected bilateral middle cerebral artery in both period of onset and intermission during simple partial seizures with Transcranial Doppler. ResultsThe mean velocity variance between focus side and non-focus side was minimums among the 3 indexes observed. The mean velocity of MCA displayed uneven increase during seizures. ConclusionThe mean velocity was the most stable index for judging.
