目的 报告使用StealthStation神经导航系统在颅脑手术中应用的经验。方法 应用StealthStation神经导航系统指导 10 6例颅内肿瘤手术进行回顾性分析。术中对导航准确性进行监测并对46例不同部位病灶进行术中脑移位检测。结果 首次平均坐标误差和 10厘米预期准确性分别为 3 6 0± 1 6 0mm和 3 12± 1 77mm ,经去除或重新注册“不准确”的皮肤坐标后两者分别降为 2 34± 0 91mm和 2 79± 0 93mm。有 5例因平均坐标误差 >4mm加用表面注册 ,其结果为 1 0 9± 0 2 4mm。 10 6例病人共 10 8个病灶 ,除了活检 1例 (0 9% )外 ,全切除 92个 (85 2 % )、次全切除 8个 (7 4% )、大部切除 7例 (6 5 % )。术中准确性分别为 1 2 2± 0 90mm和 1 2 9± 1 30mm。术后症状改善或不变 98例(92 5 % )、加重 6例 (5 7% )、死亡 2例 (1 9% )。结论 StealthStation神经导航系统在颅脑手术中提供术中动态跟踪、实时导航 ,准确可靠 ,有助于病灶全切除及降低手术并发症的发生。
Purpose To report on the experience of using the StealthStation Nerve Navigation System in craniocerebral surgery. Methods The StealthStation was used to guide the operation of 106 cases of intracranial tumors for retrospective analysis. During the operation, the navigation accuracy was monitored and intraoperative brain shift was performed on 46 cases of different parts of the lesion. Results The first mean coordinate error and the expected accuracy of 10 cm were 3600 ± 160mm and 3112 ± 1777mm, respectively, and were both reduced to 234 ± 0 91mm after removal or re-registration of “inaccurate” skin coordinates And 2 79 ± 0 93 mm. In 5 cases, the average registration error was> 4mm plus surface registration, the result was 109 ± 024mm. A total of 108 lesions were obtained in 106 patients, 92 (85.2%) underwent total resection, 8 (74%) underwent total resection, and 7 (65%) underwent total resection except 1 biopsy (0 9% %). Intraoperative accuracy was 122 ± 0 90mm and 122 9 ± 1 30mm, respectively. There were 98 cases (92.5%) with improvement or no change after operation, 6 cases (57%) were aggravated and 2 cases died (19%). Conclusion The StealthStation can provide intraoperative dynamic tracking, real-time navigation, accurate and reliable in craniocerebral surgery, which can help the total excision of the lesion and reduce the occurrence of surgical complications.
