title: [Endovascular treatment of nongalenic cerebral arteriovenous fistulas].
abstract: OBJECTIVE
  To explore the efficacies of embolization in the treatment of nongalenic cerebral arteriovenous fistula (NCAVF).
  
  
  METHODS
  The clinical data of 16 NCAVF patients (14 from Department of Neurointerventional Medicine, Beijing Tiantan Hospital and 2 from Department of Neurosurgery, Second Municipal Hospital of Yulin) undergoing embolization from April 2008 to October 2014 were analyzed retrospectively. Clinical and imaging follow-ups were conducted.
  
  
  RESULTS
  Among them, 6 patients were embolized with coils alone and the remainder coil plus Onyx glue. The digital subtraction angiography (DSA) images obtained immediately after embolization showed that complete (n = 12), near-complete (n = 2) and staged (n = 2) occlusions of NCAVFs were achieved. One patient recurred during an imaging follow-up period of 3-24 months. All symptoms and signs were relieved after embolization during a clinical follow-up period of 3-38 months.
  
  
  CONCLUSIONS
  Embolization with coil or coil-assisted Onyx embolization is both feasible and efficacious for NCAVF. Using coils helps to reduce the velocity of blood flow and assists Onyx in embolizing fistulas in patients with high-flow NCAVF.
