[Retracted] A Controlled Study of Continuous Lumbar Drainage of Fluid and Lumbar Puncture Drainage for Aneurysmal SAH after Intracranial Aneurysm Clipping

Figure 4

Comparison of cerebral artery flow velocity. Compared with the cerebral artery flow rate before treatment in the control group, there was little difference in the observation group () (a). Compared with the cerebral artery flow rate after treatment in the control group, the cerebral artery flow rate after treatment in the observation group was lower () (b). Compared with the cerebral artery flow rate before treatment in the groups, the cerebral artery flow rate after treatment in the two groups was lower () (c). indicates that the comparison is .
