PDFAbstract
Objective To study and analyze cerebrospinal fluid (CSF) flow in patients with endoscopic third ventriculostomy (ETV) compared with volunteers, to assess the surgery efficacy by investigating. Methods 30 volunteers and 12 patients with endoscopic third ventriculostomy were selected. CSF flow was measure inside the cerebral aqueduct and the stoma area separately with cine PC (Siemens Avanto 1.5T) in all case. All diffusiontensor data (Systolic Velocity、Average Velocity、Net Flows、Average Flow Rate) were processed with Argus software on workstation. Results Independent t test was processed on PSV、DSV and NF between normal and ventriculostomy and found that P ＞0.05 in all three tests. Conclusions The CSF flow pattern in patients performed with ventriculostomy in the floor of the third ventricle is similar with the normal, presenting as bidirectional periodical pulsating waves in the fistula. The cerebrospinal fluid circulation can be rebuilt by ETV, so that its normal physiological requirements can be satisfied. CSF flow waveforms analysis by MR cine PC seems to be a reliable, reproducible, and sensitive method for assessing the CSF dynamics.
