The Distending Force in the Production of Communicating Syringomyelia

The changes of syrinx volume after posterior reduction and fixation of basilar invagination and atlantoaxial dislocation with syringomyelia

“…It suggested that the The pathogenesis of Chiari malformation (CM) with or without associated BI and/or syringomyelia is very complex. One of the current concepts is that there is a reduction in posterior fossa volume which obstructs the free communication of CSF flow from the cranial to the spinal subarachnoid space [5,6,18]. Posterior fossa decompression with or without duraplasty as treatment for symptomatic CM-I with syringomyelia has shown satisfactory results except in the presence of ventral bone abnormalities [12,13,16].…”

A case report of Charcot arthropathy caused by syringomyelia and Chiari malformation complicated with scoliosis

“…The pathogenesis of Chiari malformation associated with syringomyelia was still a subject of much debate. As follows: (1) The theory of fluid mechanics [2]; (2) The theory of separated pressure of intracranial and spinal canal [3]; (3) The theory of the infiltration of cerebrospinal fluid in parenchyma of spinal cord [4]. Some authors think that the mechanism of Chiari malformation and syringomyelia induced scoliosis may be: syringomyelia damage spinal cord anterior horn and pyramidal tract, caused unbalance of paraspinal muscle, which led to scoliosis [5].…”

General Anaesthesia for Neurosurgery

“…Increase in central venous pressure is directly transmitted to the intracranial veins and may also increase c.s.f. pressure secondarily to pressure changes in the vertebral canal (Williams, 1970). Insufficient expiratory time, high expiratory resistance, coughing or straining on the endotracheal tube will increase intracranial pressure (Hunter, 1952;Schettini, Cook and Owre, 1967).…”
