摘要
目的 探讨使用德国产BrainLabVectorVision 2 无框架导航系统在鼻内镜经蝶垂体腺瘤切除术中的作用。方法 选择性研究 13例垂体腺瘤患者在无框架影像导航引导下鼻内镜经蝶入路垂体腺瘤切除患者的临床资料 ;其中巨大垂体腺瘤 7例 ,微腺瘤 4例 ,大腺瘤 2例。结果 影像导航定位误差平均 1 5mm ;重要结构和病变定位满意 ,导航注册时间平均 5min ;手术时间平均 5 0min ,术后所有患者症状均减轻和好转。术后短暂性尿崩者 4例 ,无颅内感染及出血病例。结论 无框架影像导航在内镜经蝶垂体腺瘤的手术治疗中使重要结构及病变部位定位准确 ,在手术中可发挥重要作用。
Objective To assess the role of neuronavigation in assisting endoscopic transsphenoidal surgery for pituitary adenomas Methods Ten endoscopic endonasal transsphenoidal reoperations for pituitary adenomas were selected Clinical records were reviewed retrospectively Five of 10 patients had gigantic adenoma, 3 microadenoma, 2 large adenoma Results The mean setup time was 5 minutes, and the operative time was 50 minutes in image guided procedures In all cases, the system worked well without malfunction Continuous information regarding instrument location and trajectory was provided to the surgeon Measurements of intraoperative accuracy in the axial, coronal, and sagittal planes indicated a mean verified system error of 1 5 mm for pituitary adenomas After operation, the symptoms relieved in all patients Conclusions Neuronavigation can be applied during endonasal transsphenoidal endoscopic surgery and requires a minimal amount of time It makes reoperation easier, faster, and safer
