title: [Correlations of angio-architectural factors with cerebral arteriovenous malformation hemorrhage].
abstract: OBJECTIVE
  To explore the relationship between angio-architectures of cerebral arteriovenous malformations (AVM) and hemorrhage.
  
  
  METHODS
  A total of 55 consecutive surgical cases of AVM were collected in August 2010 to May 2011 at Beijing Tiantan Hospital. There were 34 males and 21 females with an average age of 32.5 years (range: 3 - 59). The initial symptoms included bleeding (n = 20), epilepsy (n = 21), headache (n = 7), neurological dysfunctions (n = 6) and others (n = 1). The relationship between size, location, type of feeding artery, type of draining vein, complicated venous aneurysm and hemorrhage was analyzed by single factor test.
  
  
  RESULTS
  The cases of AVM fed by perforators, located in basal ganglia and post-cranial fossa, with small size, exclusively deep drainage and complicated venous aneurysm were more likely to present with hemorrhage.
  
  
  CONCLUSIONS
  The hemorrhage of AVM is significantly correlated with many factors, such as the type of feeding artery, size and location of AVM, the type of draining vein and complicated venous aneurysm. But the number of draining vein is irrelevant.
