目的探讨"4"字征在颞叶内侧癫(癎)(MTLE)致(癎)源定侧中的应用价值.方法对33例确诊为MTLE并行手术治疗和术后长期随诊(≥4年)无发作的患者术前发作录像进行回顾性的分析,重点关注54次继发性全面强直.阵挛发作(sGTC)出现的"4"字征与致(癎)源侧别的关系.结果在33例MTLE患者的共54次sGTC中,有10例(30%)患者的23次(43%)sGTC出现了"4"字征,所有"4"字征的上肢伸直侧均位于致(癎)源(切除侧)的对侧.结论在本组MTLE患者中,尽管"4"字征的发生率低,但有较高的致(癎)源定侧准确性.

Objective To investigate the lateralizing value of figure"4"sign,an asymmetrical tonic posturing observed in secondarily generalized tonic-clonic seizures(sGTC),in patients with mesial temporal lobe epilepsy.Methods Presurgical videotapes of 54 sGTC from 33 patients who were seizure-free for at least 4 years after temporal lobectomy were retrospectively reviewed.Attention was paid to the relationship between the extended upper extremity in figure"4"sign and the resected side.Results The "4"sign was observed in 10(30%)of 33 patients and 23(43%)of sGTC.The extended arm in figure "4"sign was always contralateral to the epileptogenic foci(resected side).Conclusion"4"sign has a significant lateralizing value,when present,in this selected homogeneous group of patients.
