Research Of The Interaction Between The Hydrodynamic Of Cerebrospinal Fluid And The Procedure Of Posterior Vertebral Column Resection (PVCR) In Cervical Syringomyelia With Thoracic Scoliosis Adolescents

Objective:Study of scoliosis patients with craniocervical junction region of cerebrospinal fluid dynamics characteristics, and to explore its relationship with scoliosis and syringomyelia. Contributes to disease diagnosis, treatment options and curative effect evaluation.Methods:Application of routine MRI and MR phase contrast cine magnetic resonance imaging (Phase Contrast cine Magnetic Resonance Image, PC-cine MRI)on11patients with scoliosis patients and11cases of normal people were compared with the same age,and preoperative patients, postoperative patients and postoperative3months patients were compared, and axial foramen magnum level determination of Argus cerebrospinal fluid flow; flow analysis software, measurement and calculation parameters including cerebrospinal fluid head end to end phase duration (DF). end to end phase duration (UF), calculated respectively in a CSF cycle time of the percentage of DF%and UF%, latency/a cerebrospinal fluid circulation time (SP%), cerebrospinal fluid flow down the maximum velocity (VDmax), the upward flow of the maximum velocity (VUmax), flow(FL),rendering the maximum velocity/time curve. Taking SPSS17.0software for statistical analysis, measurement data for comparison between groups in group t test, within group comparisons with paired t test;select P<0.05as there are statistically significant differences in P<0.01,there was significant difference.Results:Scoliosis group compared with the control group:VUmax and VDmax increased, DF%, UF%and FL decreased, SP%increased, the differences were statistically significant (P<0.05); preoperative patients compared with postoperative patients:VDmax and VUmax decreased, UF%,DF%,SP%and FL were not statistically significant; preoperative patients compared with postoperative3months patients:DF%, VDmax and VUmax were not statistically significant, UF%and FL increased, SP%decreased.Conclusions:1、In scoliosis patients exist the craniocervical junction abnormal cerebrospinal fluid dynamics;2、Though PVCR procedure, effective correction of spinal deformities can be achieved and improved CSF dynamic abnormal situation on craniocervical junction.3、Though PVCR procedure, CSF dynamic abnormal situation on craniocervical junction gradually improve over time.
