AIMS: To explain the use of Stereotactic Radiosurgery for intracranial lesions and report Dunedin Hospital's early experience with this treatment.
METHODS: Review of a prospective computer database and departmental clinical files.
RESULTS: 74 patients underwent 78 radiosurgical procedures between 30 July 1994 to 18 December 1997. 28 patients with arteriovenous malformations were treated with an obliteration rate of 82% (95% CI: 48% to 98%) at two years. Seventeen vestibular schwannomas (acoustic neuroma's) were treated, with follow-up magnetic resonance imaging available in eleven in whom there was no tumour progression after a mean period of twelve months. There was preservation of some hearing in all patients not already deaf, but one developed a new facial palsy and another had worsening palsy as late side effects. Other tumours, including selected metastases, gliomas and skull base tumours have been treated in smaller numbers.
CONCLUSION: Rates of arteriovenous malformation obliteration, vestibular schwannoma control, and side effects of radiosurgery in Dunedin are comparable to those reported in other uncontrolled series. Radiosurgery is quick and has a low procedure-related morbidity but does have important limitations and delayed side effects, which means the decision to treat needs to be based on thorough multidisciplinary review.
