Résumé
Objective To discuss the operation effect and the role of neuroendoscope which was used to assist the keyhole approach in treatment of intracranial aneurysms Methods The keyhole surgery with the assistant of neuroendoscope was used to treat 14 cases of aneurysm After initial exposure of pterional or superciliary arch keyhole approach with the aid of microscope,the rigis endoscpe was introduced to confirm regional anatomy,including the aneurismal neck and adjacent structure After clipping,introduced again to inspect the positions of the clip and nearby structures. Results After operation,all the 14 cases were recovered without any severe complication. Conclusions There was a sufficient exposure in the visualization of the anatomy of the aneurysm and surrouding structures,the injuries of operation were relieved,the time in operation and hospital can be shortern,as well as reliable operation effect.
Résumé
A Large-dosage vitamin C was used for treating head injuries in 24 male cats. The animals were randomly divided into three groups: the injured, control, vitamim C group. A dose of 200mg/kg of vitamim C were injected intravenously at once and 6 hours after injury. The neuropeptides in the plasma and CSF were measured. The results showed that the neuropeptides were lower significantly in vitamin C group than head-injured group. It suggests that large-dosage vitamin Cmay reduce the secondary brain damge and cerebral edema after head injury.
