title: Midaortic syndrome in childhood associated with a ruptured cerebral aneurysm: a case report.
abstract: BACKGROUND
  We present a patient with a midaortic syndrome who presented with subarachnoid hemorrhage caused by rupture of an anterior communicating artery aneurysm.
  
  
  METHODS
  A 14-year-old boy with midaortic syndrome was admitted to our hospital because of subarachnoid hemorrhage due to rupture of an anterior communicating artery aneurysm. He also developed acute renal failure due to previously controlled hypotension. After blood dialysis, successful clipping of the aneurysm was performed. The postoperative course was complicated by malignant renovascular hypertension due to midaortic syndrome. Medical treatment failed to control his hypertension; left primary nephrectomy improved his condition.
  
  
  CONCLUSIONS
  Although midaortic syndrome is rare, it may be significant as a cause of cerebral hemorrhage in childhood.
