摘要Objective To evaluate retrospectively the effectiveness of image-guided navigation techniques in the management of cerebral CMs.Methods Between July 1997 and January 2001, 44 patients underwent image-guided resection of cerebral CMs. To counteract brain shift, a small silicon catheter was implanted as a guide in the case of deep-seated lesions (except in the case of brain stem CMs) and before excision of multiple lesions. Results A total of 27 men and 17 women with a mean age of 35 years underwent surgical procedures (5 patients had multiple lesions). The lesions were located in the frontal (n=14), lobe temporal lobe (n=12), parietal lobe (n=6), cerebellum (n=6), thalamus (n=5), pons (n=5), and orbital region (n=1). Under the guidance of a StealthStation navigator, total removal of the lesions was achieved in all patients. Follow-up revealed marked improvement of preoperative symptoms in 26 patients and no additional deficits in 13 patients. Five patients suffered from additional neurological deficits, but two of them gradually improved during the follow-up period. Conclusions With the assistance of an image-guided surgical system, functional areas can be effectively avoided and surgical injury can be decreased. This system is well suited for accurate localization and safe resection of small, deep-seated CMs.
