Prognostic Analysis Of Lumbar Drainage For Intraventricular Hemorrhage Secondary To Thalamic Hemorrhage Treated By External Ventricular Drainage

Objective: To explore the prognostic analysis of lumbar drainage for intraventricular hemorrhage secondary to thalamic hemorrhage treated by external ventricular drainage.Method: Retrospective analysis of 78 patients who was diagnosed as intraventricular hemorrhage secondary to thalamic hemorrhage treated by external ventricular drainage during January 2011 to January 2019 in neurosurgical department of Shengjing hospital,China Medical University.According to with or without lumbar drainage treatment,the 78 patients were divided into two groups: group 1(with lumbar drainage treatment)and group 2(without lumbar drainage treatment).Compare the age,the gender,the type of thalamic hemorrhage,the range of thalamic hemorrhage,the Graeb’s score,the Glasgow coma scale and the degree of midline shift to ensure the comparability of the two groups.Statistical difference in central nervous system infection rate between the two groups was analyzed,which shows the short-term therapeutic effect of lumbar drainage on patients with intraventricular hemorrhage secondary to thalamic hemorrhage treated by external ventricular drainage.Additionally,statistical differences in incidence of chronic hydrocephalus,modified Rankin scale score and Karnofsky performance status between the two groups was analyzed,which shows the long-term effect of lumbar drainage on patients with intraventricular hemorrhage secondary to thalamic hemorrhage treated by external ventricular drainage.Result: The central nervous system infection rate of the two groups was 73.8% and 47.2%,respectively,with statistical significance(P>0.05).The incidence of chronic hydrocephalus of the two groups was 14.3% and 83.3%,respectively,with statistical significance(P>0.05).The relief rate of long-term modified Rankin scale score of the two groups was 38.1% and 44.4%,respectively,with no statistical significance(P>0.05).The relief rate of postoperative long-term Karnofsky performance status in the two groups was 42.9% and 47.2%,respectively,with no statistical significance(P>0.05).Conclusion: In the patients with intraventricular hemorrhage secondary to thalamic hemorrhage who undergo external ventricular drainage treatment,lumbar drainage exerts effects on reducing both the postoperative infection rate of central nervous system and the incidence of chronic hydrocephalus.However,lumbar drainage has no effect on improving the modified Rankin scale score and long-term Karnofsky performance status of these patients.
