ABSTRACT
Objective To investigate the clinical efficacy of small bone-flap decompression of posterior fossa through neuroendoscopy in the treatment of ChiariⅠmalformation.Methods Retrospectively analyzed the clinical data of 44 cases of ChiariⅠdeformity/syringomyelia who were admitted into affiliated hospital of Xuzhou medical university from January 2013 to December 2016.And divided these patients into the observation group ( n=22,treated with small bone-flap decompression of posterior fossa through neuroendoscopy ) and the control group ( n=22,treated with posterior fossa decompression/tonsillectomy) according to surgical methods .The recovery time and the postoperative com-plications of the two groups were analyzed ,and the long-term efficacy and changes in spinal cord cavity were observed through the follow-up of 1 to 20 months.Results There was no death case in both of the two groups .The effective rate of the two groups were 86.36％and 86.36％respectively.The complication rate of the observation group was 27.35％, which was significantly lower than 77.3％of the control group with statistical significance(P<0.05).There was no significant differences in the recovery time ,postoperative curative effect and spinal cord cavi-ty changes between the two groups (P>0.05).Conclusion The treatment of Chiari Ⅰmalformation with small bone-flap decompression of posterior fossa through neuroendoscopy is a new surgical procedure with less trauma ,shorter hospital stay ,less complication and less effective compared with traditional method .
ABSTRACT
Objective To investigate the clinical effect of external ventricular drainage on the prognosis of anterior communicating artery aneurysms.Methods Retrospectively collected and analyzed 96 patients of anterior communicating artery aneurysms who were treated in our hospital from June 2013 to October 2015,and they were divided into the observation group which was given external ventricular drainage treatment and the control group which was not given external ventricular drainage treatment.These patients were followed up for 6 months to 2 years,and the results of the 2 groups were graded according to the analysis of postoperative complications and the Glasgow prognostic score (GOS).Meanwhile,evaluated the general function of the patients according to the KPS score.Results The the incidence rate of complications after treatment in observation group was 54.17％,which was lower than 86.96％ in the control group,and the difference was statistically significant(P ＜ 0.05).The cure rate of observation group was 79.16％,which was higher than 50％ in the control group,and the difference was statistically significant (P ＜ 0.05).The postoperative KPS score in the observation group was (79.68 ± 13.24) points,which was higher than (62.57 ± 12.72) points in the control group,and the differences were statistically significant (P ＜ 0.05).Conclusion External ventricular drainage can reduce the compression injury of the brain tissue to a minimum degree,reduce intracranial pressure,relieve cerebral edema caused by intracranial pressure,reduce complications,and improve the prognosis of patients and the cure rate.
