Expert consensus on multidisciplinary diagnosis and treatment of brain arteriovenous malformation

Abstract

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.
