Experience with a consecutive series of 125 computerized tomographic (CT) image guided stereotaxic neurosurgical procedures, performed using the Brown‐Roberts‐Wells (BRW) system is described. Operative objectives included tissue sampling for diagnostic purposes, intra‐operative localization of craniotomy flaps and intracerebral lesions, cyst and abscess aspiration and lesion to modulate tremor. A neuropathological diagnosis was possible in 96% of the biopsies, and lesions were precisely localized in all patients undergoing microsurgical stereotaxic craniotomy. Two patients (2.2%) undergoing sterrotaxic biopsy died as a result of the procedure and one patient's hemiparesis was permanently worsened (0.8%). In only one of three patients undergoing stereotaxic thalamotomy was tremor abolished. This report confirms that (3 image guided stereotaxic neurosurgery is safe, accurate and versatile. There is, however, a moderate incidence (7.2%) of lesser complications that can occur with this type of surgery. These complications, which are emphasized in this paper, are related to both the site of surgery and the neuropathology.
