Abstract

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.
