Abstract:
Objective In this study,the authers investigate the effect of lumbar arachnoid space continuous drainage to prevent and reverse cerebral vasospasm (CVS) angiographically following experimental subarachnoid hemorrhage (SAH).Methods SAH model was achieved by cisternal magna twice injections of autolugous blood.Thirty adult mongrel dogs presented with SAH were randomly divided into five groups: early-drainage group,later-drainage group,early-puncture group,later-puncture group and control group. The lumbar puncture two groups started to puncture and exclude blood cerebral spinal fluid(CSF) 2 hours later following the second injection and on day 5 respectively,while the drainage two groups started to drain at the same time.The degrees of CVS were analyzed through cerebral angiography(%reduction of basilar artery diamiter,%RBAD). Results ①Compared with early puncture group and control group,early drainage group had less cases of CVS and the degrees of CVS were more slight which relieved within shorter period than other two groups.②Compared with later puncture group and control group,later drainage group had less cases of CVS and the period of CVS was shorter.③Compared with later drainage group,there were less cases of CVS and the degrees of CVS were more slight in early drainage group.Conclusions Lumbar subarachnoid space continuous drainage may prevent and reverse the CVS following SAH.Early lumbar subarachnoid space continuous drainage should be presented with better consequence.
