摘要:

Using interventional magnetic resonance imaging, a woman was surgically treated for a Chiari I malformation and syringomyelia. The experimental operating environment and its application to Chiari I malformation are discussed.

摘要:

Over the last dozen years several technologies have been developed to provide the spine surgeon with real-time information not available from the surgical exposure. The initial iterations of this technology involved matching anatomical points with previously captured radiographic information, such as computed tomographic scans. Although these techniques allowed more accurate placement of instrumentation, the mechanics of these devices often were cumbersome. More recent developments include the incorporation of the C-arm fluoroscope into the computer navigation system. This technique of virtual fluoroscopy allows the surgeon to navigate in several planes using preacquired fluoroscopic images while minimizing radiation exposure. The technique is relatively fast technique to learn and perform. Virtual fluoroscopy technique and its application to the lumbar and cervical spines are presented.

摘要:

Stereotactic radiosurgery is a viable treatment option for spine lesions provided the lesion can be targeted precisely and radiation can be delivered while limiting dose to surrounding critical structures. We present our treatment experience with image-guided stereotactic radiosurgery with the CyberKnife for spine lesions. Thirty-four patients with 38 lesions were treated at Stanford University from July 1997 to July 2002. These lesions included primary tumors, metastatic tumors, and vascular malformations throughout the spinal axis. The inverse treatment planning system provided highly conformal dosimetry of prescribed doses ranging from 1,400 to 2,520 cGy delivered in one to five stages. Based on skeletal landmarks and implanted fiducial markers, true image-guided treatment was delivered in an outpatient setting. This technique has been used to treat patients with spine lesions that are otherwise untreatable with low associated morbidity. Longer follow-up in a larger series is needed to more adequately assess safety and efficacy; however, this technology is a promising addition to a neurosurgeon's armamentarium.
