无框架神经导航与立体定向开颅术的比较性研究

Comparative study of frameless neuronavigation and stereotactic craniotomy

目的 :探讨无框架神经导航手术和立体定向开颅术的各自特点。方法 :回顾性总结自 1999年 2月至2 0 0 0年 12月间使用ASA - 6 0 1V神经外科导航系统完成的 38例导航手术和使用Leksell-G型定向仪完成的 6 7例立体定向开颅手术。结果 :导航组 :病灶全切 34例 ,近全切 3例 ,行动脉瘤加固术 1例。立体定向开颅组 :全组病例均完整切除病灶。二组都无严重并发症和死亡。结论 :无框架神经导航手术和立体定向开颅术 ,均属于立体定向手术范畴。对于位于颅表或皮层下的病灶 (直径≤ 5cm) ,适于行立体定向开颅术。而对于脑深部、边界不规则呈浸润性生长的病灶和颅底病灶 ,则适于行无框架神经导航手术。

Objective:To evaluate the characteristics of frameless neuronavigation and stereotactic craniotomy.Methods:38 cases underwent frameless neuronavigation using ASA-601V neurosurgical navigation system,and 67 cases underwent stereotactic craniotomy using Leksell-G system from February 1999 to December 2000 is analyzed retrospectively.Results:The group of neuronavigation:Total resection of the lesion was achieved in 34 cases,subtolal resection in 3 cases,wrapping of aneurysm in one case.The group of stereotactic craniotomy:Total resection of the lesion was achieved in all cases.No operative sustained complications and no mortality in each group.Conclusions:Frameless neuronavigation and stereotactic craniotomy are belong to stereotactic surgery.Stereotactic craniotomy is suitable to superficial lesions and subcortical lesions(diameter≤5cm).Framelesss neuronavigation is suitable to deep-seated lesions,infiltrative lesions and basicranial lesions.\;
