CEREBELLAR ARTERIOVENOUS MALFORMATIONS: CLINICAL, IMAGING FEATURES AND SURGICAL RESULTS
Main Article Content
Abstract
Objectives: analyzing clinical, imaging features and evaluation of surgical results of cerebellar arteriovenous malformations. Methods: Cross-sectional descriptive retrospective and prospective study of 32 cerebellar AVMs underwent surgery in Bach Mai hospital from 6/2018 to 6/2021. Results: 14 males and 18 females with mean age of 38 (9-66 years old). 26 cases (81,3%) presented with hemorrhage. Spetzler-Martin grading scale: 6 grade I, 17 grade II, 8 grade III, 1 grade IV. 10 patients required emergent surgery, 8 cases had received embolization before surgery. A favorable neurological outcome was observed in 26 patients (81,3%). Conclusions: Cerebellar arteriovenous malformations frequently present with hemorrhage. Cerebellar arteriovenous malformations are more likely to drain deep and less likely to be eloquent. Microsurgery for cerebellar arteriovenous malformations resection is recommended in most cases. Most patients will experience a favorable surgical outcome.
