title: [Re-bleeding predictors in patients with aneurysmal subarachnoid haemorrhage and delayed neurosurgical treatment].
abstract: OBJECTIVE
  To evaluate the re-bleeding predictors in patients with delayed treatment of aneurysmal subarachnoid hemorrhage.
  
  
  METHODS
  A prospective cohort study enrolled 261 patients with aneurysmal subarachnoid hemorrhage, attending in Hermanos Ameijeiras Hospital from October 2005, and June 2014.
  
  
  RESULTS
  An increased re-bleeding risk in the multivariate analysis was associated with grade III (OR 2.01; 95% CI; 1.06-3.84) and grade IV (OR 3.84; 95% CI; 2.06-7.31) on World Federation Neurological Surgeon (WFNS) scale; grade III (OR 2.04; 95% CI; 1.01-4.13) and grade IV (OR 2.12, 95% CI; 1.05-4.28) on the Fischer scale, aneurism location in posterior circulation (OR 2.45, 95% CI; 1.33-4.44), and anterior communicant artery (OR 1.57, 95% CI;1.00-2.46). Hypertension history was present in 60.9% (159 patients) and was also associated with risk of re-bleeding (OR 2.70, 95% CI; 1.00-7.30). Blood pressure, haematocrit, glycemic, aneurysm size, multiple aneurysms, and location in the middle cerebral artery, do not show any relationship.
  
  
  CONCLUSIONS
  Hypertension history, poor grade (III and IV) on WFNS and Fisher scale and aneurysm location were independent risks factors of re-bleeding in patients with delayed aneurysmal treatment.
