Objective  To investigate the effect of neuroendoscopic surgery in treating patients with intraventricular casting.

  Methods  A retrospective analysis was performed on the effect and prognosis of 9 patients with intraventricular casting by neuroendoscopic surgery from January 2017 to July 2019.

  Results  For patients in this study, the average indwelling time of external ventricular drainage tube was 3.5 days, and the duration of central high fever was 3.1 days. Three months after operation, 1 case had communicating hydrocephalus and was treated with ventriculoperitoneal shunt (VP shunt). For the nine patients, the mean Glasgow Outcome Scale (GOS) was (6.3±1.6) points before operation, which was lower than (9.7±1.7) points at 2 weeks after operation. There was no death case in this study. Three months after operation, GOS score showed there were 3 cases of good recovery, 4 cases of mild disability and 2 cases of moderate disability.

  Conclusion  Neuroendoscopic surgery is safe and effective in the treatment of patients with intraventricular casting, and has better prognosis.
