title: [Long-term follow-up study of postoperative revascularization in childhood moyamoya disease: results of 226 cases].
abstract: OBJECTIVE
  To study the long-term results of 226 patients with moyamoya disease ased below 15 years and to report the modified method of extra-intracranial arterial anastomosis and encephalo-myo-arterio-syn-anastomosis, etc.
  
  
  METHODS
  The mean follow-up period was 15.5 years (range 8 - 19 years). The results were obtained from the pre- and postoperative cerebral angiographic examination, MRI, CT, cerebrovascular Doppler ultrasonography, Glasgow Outcome Scale (GOS), intelligence quotient (IQ) as classified by Taft and neurological symptoms.
  
  
  RESULTS
  Of the 226 patients with childhood moyamoya disease, 64 (28%) recovered in completely, 69 (31%) in improved markedly, and 46 (20%) improved slightly. 43 patients (19%) had no changes and 4 (2%) died. The effective rate of the operation was 79%.
  
  
  CONCLUSIONS
  The modified direct anastomosis and encephalo-myo-arterio-synagiosis played a role in this improvement by increasing CBF after the operation. A significant correlation is found between the postoperative effect and the stages of preoperative angiograms.
