ASA-610V导航系统在微侵袭神经外科手术中的应用

Application of ASA-610V neuronavigation system in minimally invasive neurosurgery

目的 探讨ASA-610V导航系统在微侵袭神经外科手术中的应用效果。方法 应用ASA-610V神经外科导航系统施行各类显微神经外科手术89例,其中颅内肿瘤70例,炎性病灶12例,血管畸形7例。10例运动功能区肿瘤患者施行功能性磁共振引导下肿瘤切除导航手术。结果 系统注册误差为2.5mm左右。病灶全切除者59例(66.29％),次全及大部切除者18例(20.22％),部分切除者12例(13.48％)。80例患者预后良好,9例术后出现轻微并发症。10例运动功能区肿瘤患者均行全切除手术,术后无一例神经功能障碍加重。结论 ASA-610V导航系统在神经外科手术中定位准确,尤其对于位于颅底和功能区附近的病变,有助于提高手术切除率,降低手术并发症。

Objective The application of ASA-610V neuronavigation system in minimally invasive neurosurgery was studied. Methods The micro-neurosurgery was performed in 89 patients with ASA-610V neuronavigation system. Their disorders included intracranial tumor (n=70), inflammatory lesion (n = 12) and cerebral arteriovenous malformation (n=7). Of these lesions, 10 patients with tumor in motor function area were resected by fMR1-guided neuronavigation. Results The mean registration error of the system was about 2.5 mm. The total removal rate of these lesions was 66.29% (59/89), subtotal removal rate was 20.22% (18/89) and partial removal rate was 13.48% (12/89). The prognosis in 80 patients was good, and minimal postoperative complications occurred in 9 cases. Postoperation in patients with total removal of tumor in motor area of cerebrum, the exacerbation of dysfunction in nervous system was not found. Conclusion ASA-610V neuronavigation system can provide an accurate localization in neurosurgery, especially for the lesions in base of skull and motor functionarea, and it is helpful in increasing removal rate and decreasing the surgical complication.
