Abstract: ［Abstract］ Objective To analyze the effect of fenestration of the lamina terminalis （FLT） in the treatment of chronic hydrocephalus caused by aneurysmal subarachnoid hemorrhage （aSAH）. Methods A total of 165 patients with aneurysm were included in the study. The patients underwent elective craniotomy and aneurysm clipping in Neurosurgery Dept. of our hospital from January 2015 to December 2017. According to whether or not FLT was performed during surgery， the patients were divided into FLT group （n=72） and non-FLT group （n=93）. FLT group was composed of included gradeⅠ（9 cases）， gradeⅡ （12 cases）， grade Ⅲ （31 cases）， and grade IV （20 cases） in terms of the Fisher classification. non-FLT group includedⅠgrade （n=13）， Ⅱgrade （n=21）， Ⅲgrade （n=40）， Ⅳgrade （n=19）. All patients were followed up for 6 months. The incidence of chronic hydrocephalus between the two groups were compared. Results In the patients with FisherⅠand Ⅱ grade， incidence of chronic hydrocephalus were no statistically significant differences between FLT group and non-FLT group （χ2=0.770， P=0.380）. In the patients with Fisher Ⅲ grade， incidence of chronic hydrocephalus were statistically higher in non-FLT group than in FLT group （χ2=4.329， P=0.037）. In the patients with Fisher Ⅳ grade， incidence of chronic hydrocephalus were statistically higher in non-FLT than in FLT group （χ2=3.955， P=0.047）. Conclusion In aSAH patients with Fisher Ⅲ and Ⅳ grade， FLT can reduce the incidence of chronic hydrocephalus.
