diastematomyelia การใช้

• Adult presentation in diastematomyelia is unusual.
• Lumbosacral adult diastematomyelia is even rarer.
• The conus medullaris is situated below the L2 level in more than 75 % of these diastematomyelia patients.
• Post-myelographic CT scanning provides individualized detailed maps that enable surgical treatment of cervical diastematomyelia, first performed in 1983.
• Prenate ultrasound could also detect whether the diastematomyelia is isolated, with the skin intact or association with any serious neural tube defects.
• Diastematomyelia is a rare congenital anomaly that results in the " splitting " of the spinal cord in a longitudinal ( sagittal ) direction.
• Cervical diastematomyelia can become symptomatic as a result of acute trauma, and can cause major neurological deficits, like hemiparesis, to result from otherwise mild trauma.
• Progressive neurological lesions may result from the " tethering cord syndrome " ( fixation of the spinal cord ) by the diastematomyelia phenomenon or any of the associated disorders such as myelodysplasia, dysraphia of the spinal cord.
• Diastematomyelia ( di穉穝tem穉穞o穖y積lia ) is a congenital anomaly, often associated with spina bifida, in which the spinal cord is split into halves by a bony spicule or fibrous band, each half being surrounded by a dural sac.
• Diastematomyelia usually occurs between 9th thoracic and 1st ventral horn ( giving rise to a ventral nerve root . ) One study showed the bony spur typically situated at the most inferior aspect of the dural cleft . They advised that if the imaging appears to show otherwise, a second spur ( present in about 5 % of patients with diastematomyelia ) is likely to be present.
