Brain surgery with image guidance: current recommendations based on a 20-year assessment. 总被引:1,自引:0,他引:1

Image guidance promotes safe and effective surgical management of a wide array of intracranial diseases. To better define the historical importance of image guidance and to assess the relative contribution of each imaging modality to the safety and efficacy of selected procedures, we reviewed our 20-year experience at a single institution. A retrospective review of our departmental surgical records was performed to identify patients who underwent brain surgery with image guidance between January 1979 and January 1999. We identified the use of intraoperative fluoroscopy, endoscopy, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and angiography in 7,388 patients. During this 20-year interval, advances in neuroimaging were translated into the operating room environment. Fluoroscopic guidance received the highest overall rating and was deemed critical for the performance of successful transsphenoidal surgery (n = 436) and effective percutaneous trigeminal neuralgia management (n = 1,121). Ultrasound and angiography both had limited roles; the latter was important to successful outcomes in 64 patients undergoing aneurysm management (n = 64) and arteriovenous malformation Gamma Knife radiosurgery (n = 786). Endoscopy also had a small role but had limited cost. Beginning in 1982, a dedicated operating room CT scanner was used during both morphologic and functional stereotactic surgery (n = 1,749). After 1986, MRI was used increasingly in the management of selected functional and tumor cases (n = 337); despite great versatility for patients undergoing Gamma Knife radiosurgery, the costs were relatively high. Frameless neuronavigation (n = 263) had excellent versatility and was relatively low in cost. During the last 20 years, image guidance techniques have facilitated minimally invasive brain surgery at our institution. The relative merits of all these imaging tools depended mostly on their versatility and relative costs. Major centers currently contemplating the incorporation of image guidance into routine brain surgery need not reproduce our own learning curve. 相似文献

The role of radiosurgery in the management of chordoma and chondrosarcoma of the cranial base 总被引:5,自引:0,他引:5
Despite conventional multimodality treatment (surgery and fractionated radiation therapy), recurrence and clinical progression of cranial base chordomas and chondrosarcomas are common. The malignant behavior of these tumors is a result of their critical location, locally aggressive nature, and high recurrence rate. To explore the role of radiosurgery in the treatment of these skull base neoplasms, we assessed its use in four patients with chordoma and two with chondrosarcoma. In five of the patients, radiosurgery was used as adjuvant therapy for residual or recurrent tumors after surgical debulking, and in one patient with a chordoma, it was the primary treatment. No patient received fractionated external beam radiotherapy. All tumors were less than 30 mm in diameter and were treated with 20 Gy to the tumor margin. Skull base computed tomography and magnetic resonance images were essential to define the anatomic relationships between tumor and adjacent basal structures. During follow-up (mean, 22 mo; range, 8-36 mo), we found no progression of the treated tumor volume in any patient. Neurological deficits before treatment improved in three patients; the other three patients remained in stable neurological condition. Serial follow-up imaging studies demonstrated that two patients showed reduction in tumor size and four patients had no tumor growth. In one patient, a metastatic parietal lobe chondrosarcoma developed and was treated by microsurgery. Another patient showed tumor progression outside of the radiosurgical treatment volume. Our results attest to the value of stereotactic radiosurgery as an adjuvant or primary treatment for selected patients with chordoma or chondrosarcoma and demonstrate its potential advantages over standard fractionated irradiation. Analysis of the long-term clinical and imaging effects after radiosurgery is warranted. 相似文献
