【摘要】 本文收集经椎管碘水造影和手术证实的腰骶椎椎间盘突出症64例,分析其 X 线表现,主要是造影剂柱的前缘或侧缘出现压迹,严重者造影剂柱完全阻断;神经根增宽和神经根袖的中断或闭塞。这些改变都出现于椎间隙相当于椎间盘的平面.文中讨论椎管碘水造影的应用价值和局限性,并指出较轻微的向侧后方的椎间盘突出,如摄取仰卧后斜位片则更易显示.更多还原

【Abstract】 Sixty-four cases of lumbosacral intervertebral disc herniation studied with watersolubl contrast medium myelography were analysed.The main x-ray findings of the myelograms were:(1)focal compression of the anterior or lateral margins of the con-trast medium column at the level of the disc,but in advanced cases,complete block ofthe contrast medium was seen,and(2)widening of nerve root and displaced or oblit-erated sheath.Unfortunately,there were still some limitations in the water soluble con-trast medium myelography.It is emphasized that the supine oblique view of the myelo-gram is useful to show the smaller posterolaterally herniated discs.更多还原
