评价了10例与Arnold-Chiari I型畸形相关的脊髓灰质炎患者。 在每例患者中，在不同位置的颈部进行测压Queckenstedt试验。 没有患者显示出颈部处于伸展位置时脑脊液（CSF）流动受阻的证据;然而，所有患者均显示出颈部处于屈曲位置时完全CSF阻滞。 在9例患者中进行了C1-2椎板切除术的后颅窝减压术，之后Queckenstedt试验证明所有9例患者的CSF连通均为自由，颈部处于伸展位、中立位和屈曲位。 术后磁共振成像显示接受手术的患者的空洞缩小。 提示颈部运动引起枕大孔处脑脊液通路阻塞在空洞的形成和发展中起重要作用。
Ten patients with syringomyelia associated with Arnold-Chiari Type I malformations were evaluated. In each patient, a manometric Queckenstedt test was performed with the neck in various positions. No patient showed evidence of a block to the flow of cerebrospinal fluid (CSF) with the neck in the extended position; however, all showed a complete CSF block with the neck in a flexed position. Posterior fossa decompression with a C1-2 laminectomy was performed in nine cases, after which Queckenstedt test demonstrated free CSF communication in all nine with the neck in extension, in a neutral position, and in flexion. Postoperative magnetic resonance imaging showed shrinkage of the syrinx in the patients who underwent surgery. It is suggested that obstruction of the CSF pathway at the foramen magnum produced by neck movement is of importance in the formation and progression of a syrinx.
