摘要
目的探讨癫痫患者在药物长期控制前后SPECT异常灌注灶的动态变化。方法对77例癫痫患者药物治疗前后检查发作间期SPECT和长程EEG并对其结果进行对比分析。结果SPECT显像示异常灌注灶治疗前后无变化者占39.0%,有变化者占61.0%。治疗前异常灌注灶123个,治疗后71个,治疗前后总变化52个(42.2%)。治疗后SPECT扫描正常14例(18.2%),较治疗前的5例(6.5%)增加。长程EEG治疗前后改变36.6%(26/71),痫性放电消失42.6%。SPECT异常灌注灶动态变化模式有5种:低/高灌注灶转化为高/低灌注灶;正常转化为低/高灌注灶或相反;单灶转化为多灶或相反;高-低灌注灶同时存在;发作期间的高灌注。结论抗癫痫药物长期控制后SPECT异常灌注灶的动态变化模式为5种,对于认识癫痫的复发和治疗有重要意义。
Objective To study the dynamic changes of abnormal perfusion foci on SPECT in patients with epilepsy before and after long-term control of epilepsy with antiepileptic drugs. Methods The interictal SPECT and long-term EEG were performed before and after treatment in 77 patients with epilepsy. Results Sixty-one percent of patients demonstrated changes in the SPECT imaging before and after treatment. The number of abnormal perfusion foci before and after was 123 and 71, respectively. Fifty-two (42.3%) out of the 123 abnormal perfusion foci showed changes after treatment. After treatment 18.2% of patients showed normal on SPECT and the proportion increased compared with before treatment (6.4%). Twenty-six patients (36.6%) demonstrated EEG changes after treatment. Epileptic discharges disappeared in 23 patients (42.6%). Five models of dynamic changes of abnormal SPECT perfusion foci were found : hypoperfusion foci was transformed to hypertransfusion foei or the opposite changes ; normal SPECT imaging was transformed to hypoperfusion or hypertransfusion foci or the opposite changes ; single foci was transformed to multiple foci or the opposite changes ; both hypertransfusion and hypoperfusion foci occurred; interictal hypertransfusion. Conclusions There were five models of dynamic changes of abnormal perfusion foci on SPECT in patients with epilepsy after long-term control of epilepsy with antiepileptic drugs.
