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-2000年12月间使用ASA-601V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；全组病例均守整切除病灶，二组都无严重并发症和死亡。结果：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.\;
