无框架脑立体定向手术1434例临床分析

目的应用自行研制的无框架脑立体定向仪（CAS—R-2型）取代传统立体定向仪,实施脑立体定向手术。评价此系统的临床实用性、操作精确性和手术安全性。方法回顾性分析1997年1月至2006年1月,我们应用CAS—R-2型机器人系统,临床实施无框架脑立体定向手术1434例患者的临床资料。术后随访3—48个月（平均24个月）,观察定位精度及症状改善情况。结果临床成功完成无框架脑立体定向手术。定位操作均一次性完成,无相关手术并发症,手术有效率93．3％。结论此方法与前期普通立体定向手术比较,具有减轻患者痛苦、扩大手术范围、方便术者操作、提高手术安全性等优点。

Clinical analysis of 1434 cases of frameless stereotactic operation

OBJECTIVE: Stereotactic operations were performed using a frameless stereotactic instrument manufactured by CAS-R-2 instead of traditional stereotactic frame. The aim of this study was to assess the clinical usefulness, accuracy and safety of frameless stereotactic instrument. METHODS: The clinical data of 1434 patients was retrospectively reviewed. The mean age was 30.7 years (from 0.2 to 89.0 years). Each patient underwent frameless CT/MRI image-guided stereotactic surgery by this robot system from January 1997 to January 2006. The accuracy of position and improvement of symptom were observed. The averaged period of followed-up was 24 months (from 3 to 48 months). RESULTS: The surgical procedures were performed successfully in all cases. All targets were pointed accurately at first time during the operation. The total effective rate was 93.3% without serious operation related complications. CONCLUSIONS: Compared with the traditional stereotactic operations, this method has some advantages, such as releasing the patient's pain, convenience the doctors, extending the range of indications and increasing the safety and effective of operation.
