摘要: OBJECTIVE: The goal was to report the treatment results after a second gamma knife and compare them with obtained first treatment, as well investigate whether models predict are also applicable of previously irradiated arteriovenous malformations. METHODS: number complications posttreatment hemorrhage rate were recorded for 112 patients in study, obliterations 101 whom conclusive angiograms obtained. compared expected treatment. RESULTS: observed 62, which is not significantly different from predicted 65. There 14 5 complications. When risk preceding radiation added, similar number. Six hemorrhages Of unchanged malformation size both treatments, 2 experienced none among 81 obliterated or decreased CONCLUSIONS: obliteration surgery malformations that primary complication increases amount given. incidence lower latency period if affected by radiation.
