Abstract:
Objective To evaluate the changes of cerebrospinal fluid dynamics of Chiari malformation type I associated syringomyelia patients with phase-contrast MRI (PC-MRI).Methods Thirty cases diagnosed with Chiari malformation type Ⅰ associated with syringomyelia clinically underwent cisterna plasty treatment.Cerebrospinal fluid dynamics changes were measured before 24 h and 6 months after operation with PC-MRI.The stroke volume (SV),mean flow (MF),regurgitation fractions (RF) and the maximum peak flow velocity (Vmax) were analyzed.Results After operation,PC-MRI showed SV and MF increased,the bidirectional Vmax decreased,which had statistical difference compared with those of preoperation (all P<0.05),and the C2-3 level was the most obvious.Conclusion PC-MRI can quantitative analysis of preoperative and postoperative changes of cerebrospinal fluid flow and peak velocity.
