A relationship of microangiography and blood flow patterns in the contused feline spinal cord is reported. In transitory traumatic paraplegia, an injury from which there is a return of function in several weeks, impaired vascular perfusion occurs in the white matter through 1 hour after contusion, then stabilizes and returns to normal by 24 hours. In permanent traumatic paraplegia, an injury from which no sensory or motor function returns, the vascular perfusion of the white matter continues to decrease after 1 hour and returns to normal by 24 hours at which time irreversible damage has occurred to the major sensory and motor tracts. Within the first 30 minutes post-trauma, intramedullary vasospasm is noted. In both the transitory and permanent lesions the gray matter becomes hemorrhagic and has no evidence of perfusion by fluorescent techniques by 1 hour after injury.
本文报道了猫脊髓挫伤后微血管造影与血流模式之间的关系。在短暂性创伤性截瘫中，数周后功能可恢复，挫伤后1小时内白质血管灌注受损，然后稳定下来并在24小时内恢复正常。在永久性创伤性截瘫中，感觉或运动功能均未恢复，白质血管灌注在1小时后持续下降，并在24小时时恢复正常，此时主要感觉和运动束已发生不可逆损伤。创伤后30分钟内，可见髓内血管痉挛。在短暂性和永久性损伤中，灰质均会出血，损伤后1小时荧光技术显示无灌注迹象。
