ABSTRACT

Objective:

To investigate the clinical effect of posterior fossa decompression combined with dural reconstruction in the treatment of Chiari malformation-Ⅰ(CM-Ⅰ) complicated with syringomyelia (SM).

Methods:

The clinical data of 50 patients with CM-Ⅰ complicated with SM who were treated in Yan′an University Xianyang Hospital from June 2019 to January 2021 were analyzed. They were divided into the study group (27 cases) and the control group (23 cases) according to the surgical methods. The former received posterior fossa decompression combined with dural reconstruction, while the latter received posterior fossa decompression alone. The clinical symptom improvement, neurological function, cerebrospinal fluid dynamics and syringomyelia changes were compared between the two groups before and after the surgery, and postoperative complications were compared.

Results:

The overall clinical symptom improvement rate between the two groups had no significant difference ( P> 0.05). After the surgery, the scores of pain, sensory disturbance, dyskinesia and ataxia in the study group were higher than those in the control group (4.56 ± 0.35) points vs. (4.28 ± 0.43) points, (3.61 ± 0.82) points vs. (3.15 ± 0.73) points, (3.81 ± 0.44) points vs. (3.59 ± 0.50) points, (4.43 ± 0.41) points vs. (4.09 ± 0.53) points, there were statistical significant ( P<0.05). After the surgery, the cerebrospinal fluid stroke volume (SV) and mean flow (MF) in the study group were higher than those in the control group (0.05 ± 0.02) ml vs. (0.04 ± 0.01) ml, (0.05 ± 0.01) ml/s vs. (0.04 ± 0.01) ml/s; the maximum peak flow velocity (V max) of the head and tail in the study group were lower than those in the control group (3.14 ± 1.05) mm/s vs. (3.87 ± 1.13) mm/s, (5.56 ± 1.38) mm/s vs. (6.43 ± 1.22) mm/s, there were statistical significant ( P<0.05). There were no significant differences in the rate of reduction or disappearance of syringomyelia, the rate of no change and the rate of increase of syringomyelia after the surgery between the two groups ( P>0.05). There was no significant difference in the incidence of postoperative complications between the two groups ( P>0.05).

Conclusions:

Posterior fossa decompression combined with dural reconstruction in CM-Ⅰ complicated with SM can better improve cerebrospinal fluid dynamics, and promote the reduction of syringomyelia without increasing postoperative complications.
