This study presents a new and simplified method of creating cingulate gyrus lesions by using stereotaxis guided by magnetic resonance imaging (MRI). Previous methods have utilized ventriculogram-guided stereotaxis requiring indirect cingulate gyrus localization and general anesthesia. With the present technique a BRW stereotactic frame was applied with the patient under local anesthesia. An MRI scan was performed using a T1 signal (TR, 600 ms; TE, 30 ms) in the coronal plane with 5-mm thick sections spaced every 6 mm. The coronal slice 24 mm posterior to the anterior tip of lateral ventricle was identified. The center of each (right and left) cingulate gyrus was identified as a target area, and appropriate coordinates were determined. Approach parameters were calculated for the right and left gyri using an azimuth of 45 degrees and 315 degrees, respectively, and a declination of 45 degrees. A radiofrequency electrode was stereotactically placed so that the electrode tip was at a target point which was the center of the cingulate gyrus. A radiofrequency lesion (75 degrees, 60 seconds) was made in each hemisphere's cingulate gyrus. Four patients with intractable terminal cancer pain have been initially treated in this manner. The lesions were well-localized on postoperative MRI scans. There have been no complications except for perilesional edema for 10 days in 1 patient (treated with longer radiofrequency settings that have subsequently been modified).(ABSTRACT TRUNCATED AT 250 WORDS) |
