This study was performed to assess the impact of gamma knife radiosurgery (RS) in the treatment of glomus jugulare tumors. Between February 1993 and February 1999, thirteen patients (9 women, 4 men; mean age 63.5 years, range 29 to 79 years) underwent stereotactic radiosurgery for glomus jugulare tumors with the Leksell Gamma Knife at the Neurosurgical Department of the University of Vienna. Four patients, mean age 74.5 years, range 67 to 79 years, underwent radiosurgery as the only treatment. Nine patients received radiosurgery as adjuvant therapy after previous treatment had failed: surgical resection in 9 patients and additional fractionated external beam radiation in two of these patients. Pretreatment evaluation included the staging of all tumors according to the Fisch Classification: De1 (7), De2 (1), Di1 (4) and Di2 (1). The mean follow-up period was 4.2 years, range 0.7 to 6.7 years. Ten patients, 77 %, were treated prior to 1997, the mean follow-up period being 5 years. Six patients showed no clinical changes, while six experienced an improvement of their clinical symptoms and neurological deficits. One patient was lost to follow-up. Radiation-induced transient cranial nerve neuropathies were observed in two patients. Serial MRI scans revealed tumor control in all patients, with unaltered tumor size in 10 and shrinkage in three patients. The results indicate that RS is an attractive treatment option for glomus jugulare tumors and will occupy an increasingly important role in the management of these tumors in selected patients.
SR for brain metastases from colorectal cancer results in a high local tumor control rate of 94% associated with few complications and therefore provides patients with a higher quality of their remaining life.
There are only a few long-term studies on microsurgical disc operations, and none concentrated on long-term follow-up of therapy-resistant sciatica. A total of 258 patients whose only neurologic symptoms were sciatica were included in this study. Patients were operated on between 1990 and 1997. All outcome results have been performed by an independent reviewer. The mean follow-up period was 7.3 years (range 4-11 years). At follow-up 25% of the patients were free of pain, 66% demonstrated marked improvement, and 9% had either no improvement or worsening of pain. At follow-up 65% of the patients reported returning to their original occupation or being able to go into retirement without hindrance. A total of 15% required changing of profession following discectomy (75% of these patients applying for early retirement were rejected), 6% were incapacitated and unable to work, and 14% were forced into early retirement. Patients with a history of sciatica longer than 3 months acquired failed back surgery syndrome considerably more often than those <3 months (p = 0.005).
We analysed seventeen patients with septic postoperative spondylodiscitis (POD) who were managed by early microsurgical removal of the infected necrotic tissue, application of a closed suction-irrigation system (for a mean of 6.7 days), and early mobilisation. The POD was diagnosed clinically by elevated erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) values and radiographically by computerised tomography scanning or magnetic resonance imaging. According to the sensitivity studies of the obtained pathogens, systemic antibiotics were given, followed by early mobilisation of all patients in a light cast corset. Immediate pain relief was noted in all patients except one, who required a third operation that was followed by rapid clinical improvement. Bacteriological diagnosis was obtained in 88% of the patients. Excellent or good clinical long-term results were achieved in 82% of the patients, whereas 18% had poor results. Elevated ESR/CRP values returned to normal ranges within 6 to 44 days (mean 15 days) after reoperation. All but one patient tolerated early mobilisation (within 2 to 4 weeks) well without any complication. Early microsurgical removal of the necrotic and infected tissue and application of a closed suction-irrigation system supported by specific antibiotic therapy should be considered an effective means to treat POD, thereby avoiding a prolonged period of unpleasant immobilisation for the patient.
Study design: Retrospective outcome measurement study. Objectives: Patients suering from malignant tumour disease and metastases to the spine develop a variety of clinical complaints including radicular symptoms and/or spinal cord compression syndromes. Palliative decompressive laminectomy with total or partial tumour resection is an acknowledged method of treatment, despite controversy. Setting: The Department of Neurosurgery of the University of Vienna. Method: Patients suering from metastases with predominant in®ltration of the dorsal epidural parts, or patients who could not be operated on via an anterior approach, were included. Eighty-four patients who met these criteria underwent decompressive laminectomy with total or partial tumour removal. The study analyzed motor function, pain relief and continence in a 2-and 4-month post-operative follow-up. According to the criteria of motor performance, 20% of the patients had been mobile pre-operatively. Results: In the immediate post-operative period 45%, after 2 months 33% and after 4 months 26%, were considered mobile. None of the paraplegic patients showed functional improvement. The median survival time was 6.5 months. Pre-operatively, 56% of the patients had shown continence dysfunction. Post-operatively, 38%, and after 2 months 46% of the patients, developed continence disorders. A signi®cant reduction in analgesic medication was also observed in the post-operative period. Conclusion: In our series, palliative laminectomy with total or subtotal tumour reduction in patients with malignant spinal metastatic disease resulted in amelioration of motor function, pain and continence and therefore improved the patients' quality of life. The improvement in quality of life shows that this method is a valuable option in neurosurgical therapy, except for cases with pre-operative paraplegia. However, in patients with severe pre-operative paraparesis, the authors recommend laminectomy only in very exceptional cases, because of the poor post-operative neurological results.
