[Expert consensus on multidisciplinary diagnosis and treatment of brain arteriovenous malformation].

Brain arteriovenous malformation (BAVM) is a cerebral vasculature disorder caused by gene mutation. Current available treatment measures include surgical resection, interventional embolization and stereotactic radiosurgery. The three therapeutic methods have their own advantages for different vascular structures.However, due to the complex vascular architecture of the lesion and its close anatomical relationship with brain tissue, any single treatment can not safely and effectively treat all BAVM cases. Therefore, in order to better regulate and guide the clinical diagnosis and treatment of BAVM patients in China, the National Medical School for Neurological Diseases, the Professional Committee of Neurointervention of the Chinese Medical Doctor Association and the radio-neurosurgery Expert Committee of the World Chinese Neurosurgeons Association jointly discussed and formulated this expert consensus. After in-depth analysis of the evidence of evidence-based medicine at home and abroad, the expert group combined with the specific situation of China, and gave 33 recommendations on specific clinical diagnosis and treatment issues such as predictive factors of cerebral arteriovenous malformation hemorrhage, clinical risks during pregnancy, imaging diagnosis measures, and clinical treatment strategies, in order to provide guidance for the diagnosis and treatment of BAVM nationwide.脑动静脉畸形（BAVM）是一类基因突变导致的难治性脑血管结构异常疾病，目前的治疗措施包括手术切除、介入栓塞以及立体定向放射治疗。三种治疗方式针对不同的病变血管结构各具优势，但受限于病变复杂的血管构筑及其与脑组织密切的解剖关系，任何单一治疗措施都无法安全有效地治疗所有BAVM病例。为了更好地规范和指导我国BAVM患者的临床诊疗，国家神经疾病医学中心、中国医师协会神经介入专业委员会以及世界华人神经外科医师协会放射神经外科专家委员会经共同讨论，制订了本专家共识。经过深入分析国内外循证医学证据，专家组结合我国的具体情况，给出针对BAVM出血预测因素、妊娠期临床风险、影像学诊断措施、临床治疗策略等具体临床诊疗问题的33条推荐意见，以期为全国范围内BAVM诊疗提供指导。.
