Objective To investigate the efficacy of neuroendoscopy combined with urokinase in the treatment of spontaneous intraventricular hemorrhage.Methods From August 2014 to August 2017,91 spontaneous thalamic hemorrhage ruptured into ventricles patients in Affiliated Hospital of the Yangzhou University were enrolled,who were underwent surgical treatment in this retrospective study.The patients were divided into the study group(n =41) and control group(n =50) based on different methods of treatment.The patients in the study group were given with remove visible intraventricular hematoma by neuroendoscopy,followed by External Ventricular Drainage (EVD) combined with urokinase fibrinolysis.The patients in control group were given with EVD combined with urokinase fibrinolysis.The time of postoperative drainage,ICU stay,duration of onset of fever,the number of intracranial infections,and the proportion of Glasgow outcome scale (GOS) (1 to 5) at 6 months postsurgery were compared between two groups.Measurement data were expressed as (Mean ± SD),and t test was used for measurement data.The count data were analyzed by x2 test or nonparametric rank sum test.Results The time of postoperative drainage,the number of intracranial infections,ICU stay in study group were (6.19 ± 1.1) d,5 cases,(2.8 ± 1.6) d,the indexes in control group were (7.06 ± 1.3) d,15 cases,(5.2 ± 2.0) d.The time of postoperative drainage,ICU stay,the number of intracranial infections were superior to those of the control group,and the difference was statistically significant.The proportion of GOS (1 to 5) at 6 months after surgery was 5 cases (12.2％),5 cases (12.2％),10 cases (24.4％),14 cases (34.1％),7 cases (17.1％) in study group,the indexes in control group were 10 cases(20.0％),13 cases (26.0％),11 cases(22.0％),10 cases(20.0％),6 cases(12.0％).The 6-month postoperative GOS of the study group were superior to those of the control group,and the difference was statistically significant (P ＜ 0.05).Conclusion Neruendoscopy combined with urokinase in the treatment of spontaneous intraventricular hemorrhage can reduce the time of postoperative drainage and the incidence of intracranial infection,shorten the time of ICU stay and improve the functional prognosis of the patients.
