[Computer-assisted planning for neurosurgery: a clinical study].

OBJECTIVE: To investigate the clinical effect of computer-assisted planning for neurosurgery (CAPN). METHODS: 100 groups of directional targets were randomly sampled. The targets' directional three-dimension coordinates measured with CAPN and those measured by traditional reading device were analyzed statistically. CAPN was actualized in 137 cases of stereotactic operation. RESULTS: The data measured with CAPN and those with traditional reading device were analyzed with two samples. The paired t test showed no statistically significantly difference between the data of targets measured by both methods (t < t(0.05/2,99)=1.984, P >< 0.05). Different kinds of operation based on CAPN were performed upon 137 cases success fully. CAPN was proved reliable. All operations were successful and the clinic effects satisfactory. CONCLUSION: CAPN is accurate and reliable, and has positive effect on the improvement of stereotactic neurosurgery.

[Stereotactic biopsy for intracranial deep lesions].

OBJECTIVE: To investigate the histological diagnostic efficacy and accuracy of stereotactic biopsy for intracranial deep lesions under computerized tomography (CT) and magnetic resonance imaging (MRI) guidance. METHODS: CT or MRI-guided stereotactic biopsy was performed in 605 cases with intracranial deep lesions. All the procedures were done under local anesthesia with Leksell stereotactic system. CT or MRI film was used to determine the coordinate in 450 cases and the computer-assisted planning for neurosurgery (CAPN) in 155 cases. RESULTS: Brain tumors, inflammatory lesions, and abnormal but nonspecific lesions were diagnosed pathologically in 537 cases (88.75%), 30 cases (4.96%), and 13 cases (2.15%) respectively. In 20 cases (3.31%) the biopsy procedure failed to provide useful pathological evidence. The total positive rate of biopsy was 96.69%. Complications associated with biopsy occurred in 18 patients (2.98%), and 2 patients (0.33%) died following the procedure. CONCLUSION: Stereotactic biopsy using MRI-guided stereotactic approach or CT-guided technique is a safe and reliable method for histological diagnosis of intracranial deep lesions.
