Pulsatile cerebrospinal fluid dynamics in Chiari I malformation syringomyelia

Abstract

Syrinx and premedullary cistern velocities are related to an early improvement of symptoms in patients with CM-1 syringomyelia who underwent PFD. The existence of a biphasic pulsatile systolic-diastolic CSF pattern inside the syrinx validates the "transmedullary" theory about the syringogenesis.
