[Using MR PC cine to evaluate CSF dynamics in neuroendoscopic third ventriculostomy:an analysis of 146 cases].

Objective: To evaluate the change of CSF dynamics using MR PC Cine for neuroendoscopic third ventriculostomy.

Methods: 146 cases of hydrocephalus were treated by neuroendoscopic third ventriculostomy including 36 cases checked with MR PC Cine study randomly. The successful result was assessed by clinical symptom and imaging study. All the patients were given 3 months to 1 year follow-up.

Results: The symptoms of 121 (83%) patients were recovered soon. CT, MRI and MR PC Cine demonstrated the CSF velocity, flow rate and dynamics change to the normal level compared with preoperative check. The effective rate of this group was 75.3% with one year follow-up.

Conclusion: The method of MR PC Cine to evaluate the CSF dynamics result for neuroendoscopic third ventriculostomy is simple, fast and safe. It is worth the clinical application.
