title: [Effect of drainage of the cerebrospinal fluid at the acute period of aneurysmal subarachnoid hemorrhage on the formation of hydrocephalus].
abstract: OBJECTIVE
  To discuss the effect of drainage of the cerebrospinal fluid (CSF) at acute period after aneurysmal subarachnoid hemorrhage (SAH) on the formation of hydrocephalus.
  
  
  METHODS
  Eighty-four patients with aneurysmal SAH were randomly divided into two groups according to therapeutic regimen. Forty-two cases in specific treatment group were given intravascular embolism at the acute period of hemorrhage after a ruptured aneurysm, then CSF was drained immediately. Forty-two cases were in conventional expectant treatment group. Clinical data and incidence of hydrocephalus of specific treatment group and conventional expectant treatment group were analyzed.
  
  
  RESULTS
  Clinical data did not show any differences between two groups, so they could be compared (all P>0.05). The incidence rate of acute hydrocephalus in specific treatment group was 7.14% (3/42 cases), that of subacute hydrocephalus was 4.76% (2/42 cases), and that of chronic hydrocephalus was 16.67% (7/42 cases). The total incidence rate was 28.57%. In conventional expectant treatment group, the incidence rate of acute hydrocephalus was 23.81% (10/42 cases), incidence of subacute hydrocephalus was 9.52% (4/42 cases), and that of chronic hydrocephalus was 35.71% (15/42 cases), and total incidence rate was 69.05%. There was significant difference between specific treatment group and conventional expectant treatment group in incidence of acute and chronic hydrocephalus (acute chi (2)=4.46, chronic chi (2)=3.94, both P<0.05), and there was no difference in subacute hydrocephalus between two groups (chi (2)=0.72, P>0.05), but significant difference was found in total incidence rate between two groups (chi (2)=13.77, P<0.01).
  
  
  CONCLUSIONS
  Embolization of the intracranial aneurysm with interventional treatment at the acute hemorrhage stage (within 7 days) for the aneurysmal SAH, followed by immediate drainage of CSF can prevent hydrocephalus or alleviate hydrocephalus, and the treatment plays a significant role in the formation and development of hydrocephalus.
