[Effects of puerarin on the vascular active factor related to cerebral vasospasm after aneurysm subarachnoid hemorrhage].

Objective: To investigate the effects and possible mechanisms of puerarin on the vascular active factors correlated to cerebral vasospasm (CVS) after aneurysm subarachnoid hemorrhage (aSAH).

Methods: Fifty-four patients with aSAH were randomly assigned to the puerarin group (30 cases) and the control group (24 cases) by lot. On the basis of routine treatment, the patients in the puerarin group were intravenously dripped with 0.
