Abstract

The authors outlined the treatment result of arteriovenous malformations (AVMs) inside the brainstem by reviewing the 4 existing studies in detail. The majority of patients with brainstem AVMs had a history of hemorrhage, leading to neurological deficits at the time of treatment in 72-73% of patients. The most frequent location was the midbrain or the pons depending on studies, while the medulla oblongata was the least common location throughout the series. The obliteration rate after radiosurgery was 44-73%, which was generally lower than in other locations, while the complication rate was 5-14%, which was expectedly higher than in other locations. No objective evidence for size is known, and therefore, patient selection and treatment planning should be carefully performed after judicious assessment of treatment risks and benefits among limited treatment options.
