Within 3 weeks of definitive surgery, 609 patients with histologically demonstrated, supratentorial malignant glioma were randomized to receive, in addition to 6000 rads of radiotherapy, one of four treatment regimens: carmustine (BCNU), high-dose methylprednisolone, procarbazine, or BCNU plus high-dose methylprednisolone. We analyzed the data for the total randomized population and for the 527 patients (87% with glioblastoma multiforme) in whom the initial protocol specifications were met (the valid study group). Significantly longer survival was experienced by patients receiving procarbazine or BCNU alone compared to those receiving only high-dose methylprednisolone. No other pairwise comparisons demonstrated differences significant at the 0.05 level. However, the combination of BCNU plus high-dose methylprednisolone tended to be less effective than BCNU alone in patients with poor prognosis. This study indicates that BCNU and procarbazine are moderately useful agents in conjunction with radiotherapy for patients with malignant glioma. In addition, future protocols may allow use of corticosteroids in conventional dosages for treating cerebral edema and controlling symptoms; conclusions based on survival as the endpoint are unlikely to be affected by administering steroids at somewhat greater than the usual dose. More effective regimens for the treatment of malignant glioma should be sought. 相似文献

BACKGROUND: Anterior cervical spinal surgery has been used to treat a variety of conditions including spondylosis, fracture, tumor, infection, trauma, and instability. Esophageal perforation, a rare and unusual complication of anterior cervical procedures, has been largely relegated to only incidental case reports with few large retrospective studies performed to determine true incidence, treatment, etiology, and outcome. METHODS: More than 3000 anterior cervical spine surgeries conducted over a 30-year period by 5 active practicing surgeons were reviewed. There were 3 cases of esophageal injury identified with subsequent critical evaluation to determine presentation, diagnosis, risk factors, management, and outcomes. In addition, incidence rates were calculated based on overall occurrence and antecedent risk factors. RESULTS: Two of the patients with esophageal injury had predisposing risk factors, including diverticula or cervical spine trauma. The third patient had no antecedent risk factors. Symptoms included axial spine pain, odynophagia, dysphagia, purulent spondylitis, and sepsis. Treatment consisted of one or more of the following: reoperation with exploration and repair, esophageal diversion, esophageal rest, antibiotic administration, and wound drainage. Functional outcomes were achieved in all cases with no deaths. CONCLUSIONS: Esophageal injury incidence based on overall occurrence in this study was 0.1%. Patients with no antecedent risk factors had an incidence of 0.03%. Our results compare favorably with those of the Cervical Spine Research Society survey from 1989, which predicted an incidence of 0.25% based on questionnaires filed by surgeons, representing 1 of only 2 reports that included more than 1000 patients. 相似文献

The surgical treatment of Chiari I malformation 总被引:16,自引:0,他引:16
Summary A retrospective study was undertaken on 133 patients with a Chiari I malformation treated within the last 16 years at the Departments of Neurosurgery at the Nordstadt Hospital Hannover, Germany, and the University of California, Los Angeles, U.S.A. Ninety-seven patients presented with symptoms related to accompanying syringomyelia and 4 with associated syringobulbia. They underwent 149 surgical procedures and were followed for a mean of 39±52 months. A decompression at the foramen magnum was performed in 124 patients, while 22 of those with syringomyelia were treated by shunting (7 syringosubarachnoid shunts, 15 syringoperitoneal or -pleural shunts), and 3 by ventriculoperitoneal shunts for hydrocephalus.Except for ventriculoperitoneal shunting, at least a short-term decrease in size of an associated syrinx was observed for all procedures in the majority of cases. However, no long-term benefit was observed for syrinx shunting operations. The best clinical longterm results were obtained with decompression of the foramen magnum in patients with (86% free of a clinical recurrence) and without syringomyelia (77% free of a clinical recurrence). We advise against syrinx shunting, a large craniectomy, and obex plugging which are associated with higher recurrence rates. Instead, surgery should consist of a small craniectomy, opening of the dura, archnoid dissection to establish normal cerebrospinal fluid (CSF) outflow from the 4th ventricle, and a fascia lata durai graft. 相似文献

There have been few reports documenting primary myxopapillary ependymomas in the sacrococcygeal region that result in extensive involvement of the sacrum. We present a 21-year-old man whose CT and MR findings showed massive bony destruction of the sacrum and a large lobulated soft tissue mass. Myxopapillary ependymoma should be included along with giant cell tumor, chordoma, and aneurysmal bone cyst in the differential diagnosis of a destructive osteolytic sacral lesion. 相似文献

High-resolution surface-coil MR imaging reveals intricate anatomic detail of the cervical spinal canal and its neurovascular contents. Appreciation of the normal neurovascular anatomy provides a scientific foundation for the detection of disease. Sagittal, axial, and oblique MR images of normal subjects were correlated with comparable anatomic sections obtained with a cryomicrotome whole-organ sectioning technique. The anterior epidural venous plexus is a prominent structure in the cervical spinal canal and was consistently identified both with cryomicrotomy and with MR in sagittal and axial planes. Epidural veins can be displaced and distorted in patients with cervical disk disease. Nerve roots including dorsal and ventral rootlets were consistently identified on axial images coursing through the subarachnoid space. Oblique-plane imaging showed nerve roots "en face" in their respective foramina; this may be a useful imaging technique in the diagnosis of nerve root impingement. 相似文献
