Abstract:
Objective To gain more pathophysiolgic knowledge about acute obstructive hydrocephalus and to explore its rapid and effective treatment by establishing canine acute obstructive hydrocephalus model.Methods Acute obstructive hydrocephalus model was established by injecting cyan-acrylic gel glue into the fourth ventricle via posterior fosse craniotomy in 9 male adult mongrel dogs.At the same time,lateral ventricle catheterization were performed and were fixed on the scalp to connect reservoir bag so that the changes of intracranial pressure (ICP) could be measured dynamically,and the changes of neurological function were observed.Results Acute obstructive hydrocephalus model was successfully established in 6 of the total 9dogs.ICP was (48.2 ± 6.1 ) cm H2 O at 48 hours after the injection and was (56.4 ± 5.7 ) cm H2 O at 72 hours after the injection,it increased 392％ and 459 ％ respectively.And the ICP after injection was significantly different(P ＜ 0.01 )compared with that before injection (12.3 ± 3.1 )cm H2O.Conclusion The establishment of acute obstructive hydrocephalus model has high success rate,and is easy to reduplicate; ICP could be measured dynamically and also could be reduced by releasing CSF;Thus,ventricular drainage is the most rapid and effective treatment for acute obstructive hydrocephalus.
