计算机辅助立体定向手术在颅内病变诊断治疗中的应用

目的：利用计算机技术在图象和数据处理方面的优势，扩大立体定向手术临床应用范围，提高立体定向手术的安全性、准确性和实用性。方法：以“ＢＨ”机器人定向系统为基础，以ＣＴ影像技术为引导方法，对颅内占位性病变为主的６类疾病进行不同方式的立体定向手术。结果：顺利成功地开展了４２例５０次立体定向手术，手术成功率１００％，无手术死亡，无并发症，术后近期症状好转率达１００％，病理诊断符合率为９５％。结论：计算机辅

THE USE OF COMPUTER AIDED STEREOTACTIC OPERATION IN THE DIAGNOSIS AND TREATMENT OF THE INTRACRANIAL LESIONS

Objective:Using the superiorities of the computer in processing graphics and data,to exted the clinical application of the stereotactic operation and improve its safety, accuracy and practicality. Methods:Based on BH robot stereotactic system, by applying the CT graphics technology to perform stereotactic operations for six types of diseases mainly introcranial occupying lesions. Results:Have performed 50 operations of 42 cases smoothly and successfully, the success percentage of shortly postoperative improvement is up to 100% and pathological diagnosis accordance is 95%. Conclusion:The rationally designed computer aided stereotactic system excels at the serviceabelity, it can give us clear graphic processing, accurate target-choosing and the credibility of three-dimensional coordinate data. The convenience, simpleness, rapidness and high safety invest it the extensive clinical practical value.
