Objective:To compare the effects and complications of ventriculoperitoneal shunt at different puncture points in the treatment of secondary communicating hydrocephalus.Methods:The clinical data of 122 patients with secondary communicating hydro-cephalus were retrospectively analyzed.According to different surgical methods,the patients were divided into 57 cases in frontal horn group(puncture via frontal horn of lateral ventricle)and 65 cases in occipital horn group(puncture via occipital horn of lateral ventri-cle).The surgical related indicators,preoperative and 1-week postoperative cognitive function[Glasgow Coma Scale(GCS)]and inci-dence rates of complications were compared between the two groups of patients.Results:There were no significant differences in surgical time,intraoperative blood loss,hospitalization time and adjustment rate of secondary surgery between groups(P>0.05).The good rate of postoperative shunt tube position in frontal horn group was higher than that in occipital horn group(P＜0.05).The total incidence rate of complications in frontal horn group was lower compared to occipital horn group(P＜0.05).No obvious difference was observed in GCS score between groups before surgery and on the day and about 1 week after surgery(P>0.05).Conclusion:Both surgical methods can improve the cognitive function of patients.Compared with ventriculoperitoneal shunt through occipital horn puncture for pa-tients with secondary communicating hydrocephalus,frontal horn puncture can more effectively enhance the good rate of postoperative shunt tube position and reduce the incidence rates of complications,it is worthy of application and promotion.
