海马硬化合并局灶性皮质发育不良致难治性颞叶癫痫手术预后的影响因素

Analysis on prognostic factors in surgery for refractory temporal lobe epilepsy induced by hippocampal sclerosis with focal cortical dysplasia

目的 探讨影响海马硬化(hippocampal sclerosis,HS)合并局灶性皮质发育不良(focal cortical dysplasia,FCD)双重病理所致难治性颞叶癫痫手术预后的因素。方法 回顾性分析45例病理学证实为双重病理(HS合并FCD)致难治性颞叶癫痫手术患者的临床资料。术后随访1~5年,将随访结果进行Engel分级,Engel Ⅰ-Ⅱ级者为治疗有效组,Ⅲ-Ⅳ级者为治疗无效组。应用二元Logistic回归分析影响预后的相关因素。结果 术后Engel分级:治疗有效组29例(64.4%),其中Ⅰ级者27例、Ⅱ级者2例;治疗无效组16例(35.6%),其中Ⅲ级者9例、Ⅳ级者7例。二元Logistic回归分析示,病理分型为FCD Ⅲa型(P=0.032,OR=6.098,95% CI=1.167~31.863)和致痫灶是否完全切除(P=0.002,OR=13.487,95% CI=2.574~70.679)对手术预后的影响有统计学意义;而发病年龄、术前发作频率、病程、手术年龄、有无高热惊厥史、头颅MRI是否异常对手术预后的影响均无统计学意义(均P>0.05)。结论 病理分型为FCD Ⅲa型、完全切除致痫灶是双重病理(HS合并FCD)所致颞叶癫痫手术预后良好的影响因素。

Objective To study the prognostic factors of surgical operation in patients with refractory temporal lobe epilepsy(TLE) induced by dual pathology of hippocampal sclerosis(HS) with focal cortical dysplasia(FCD).Methods The clinical data of 45 patients with refractory TLE induced by pathological proved dual pathology(HS with FCD) were analyzed retrospectively.The postoperative follow-up ranged from 1 to 5years,according to the follow-up results.Engel classⅠ-Ⅱwere taken as the effective treatment group and Engel class Ⅲ-Ⅳ were taken as the ineffective treatment group.The binary logistic regression analysis was used to investigate the factors influencing the prognosis of surgery.Results 29 (29/45) patients were in the effective treatment group.Among them,27 were Engel class Ⅰand 2 were Engel class Ⅱ.16(16/45) patients were in the ineffective treatment group.Among them,9 were Engel class Ⅲ and 7 were Engel class Ⅳ.Binary logistic regression analysis showed that histopathological subtypes were FCDⅢa or not (χ^2=4.593,P=0.032,OR=6.098,95% CI=1.167-31.863) and complete resection of epileptogenic area or not(χ^2=9.477,P=0.002,OR=13.487,95% CI=2.574-70.679) were statistically significant.Onset age,preoperative seizure frequency,course of onset,age at operation,having a history of febrile seizure or not and positive or not on MRI were not statistically significant(P> 0.05 ).Conclusion The operative prognoses of the patients with TLE induced by dual pathology(HS with FCD) are associated with histopathological subtypes,complete resection of epileptogenic area.
