Pathophysiology of primary spinal syringomyelia.

摘要: Object The pathogenesis of syringomyelia in patients with an associated spinal lesion is incompletely understood. authors hypothesized that primary syringomyelia, a subarachnoid block effectively shortens the length space (SAS), reducing compliance and ability theca to dampen CSF pressure waves produced by brain expansion during cardiac systole. This creates exaggerated every heartbeat act on cord above drive into create syrinx. After syrinx formed, enlarged compress external surface cord, propel fluid, promote progression. Methods To elucidate pathophysiology, prospectively studied 36 adult lesions obstructing SAS. Testing before surgery included clinical examination; evaluation anatomy T1-weighted MRI; measur...
