Objective: Study on the efficacy of embolisation of craniofacial arteriovenous malformations. Subjects and Methods: A cross-sectional study on 26 patients of cf AVM were embolised at Vietduc hospital from 1/2011 to 4/2014. Results: Total 26 patients (19 male and 7 female), mean age 32,46. Clinical stage . according to Schobinger's classification: 19 (73.1 percent) in stage II, 6(23.1 percent) in stage III and 1 (3.8 percent) in stage IV. On the DSA, average size of cf-AVM was 8.1 +/- 4.27 cm, the size of 5-10cm occupied 12/26 (46.2 percent). The common supplying arteries include maxillary, facial, supeficial temporal, posterior auricular apd occipital. The average number of embolised arteries for a patient was 4.3 +/- 2.22, and 13/26(50 percent) cases with percutenous embolisation. The mainly used agent was nBCA mixed with Lipiodol. The embolised percentage of 100 percent was 11/26 (42.3 percent) and 76-99 percent accounting for 14/26 (53.8 percent). The common signs of postembolisation are pain and swelling. There were 19/26 patients underwent surgery, of which 7/19 (36.8 percent) with no tlemorrage and 13/19 (68.4 percent) no required blood transfusion. Conclusion: Embolisation is effective method for the treatment of cf-AVM.
