摘　　要：本文观察了５０例手术证实的腰椎管狭窄症椎管造影表现，结合３０例正常对照，着重研究造影柱形态改变，神经根鞘袖的充盈状况，硬外隙宽度和硬囊矢径的变化。结果表明，若硬外隙宽度在Ｌ３～Ｌ４椎间水平大于４ｍｍ、Ｌ４～Ｌ５大于５ｍｍ、Ｌ５～Ｓ１大于６ｍｍ或硬囊矢径小于８ｍｍ，提示有椎管狭窄。其造影表现可分为６种类型①束腰型②残根型③单侧压迹型④节段性充盈缺损型⑤藕节型⑥长柱型。本研究不仅可提高对腰椎管狭窄症的诊断水平，同时也为设计手术方案提供了更可靠的依据。Myelographic findings were studied in 50 patients who underwent surgical exploration forspinal stenosis. Radiological appearance of contrast column and filling condition of the axillary pouches of thenerve root were emphatically observed. Comparing with the control group of 30 cases, the width of theepidu-ral space and sagittal diameter of the dural sac were measiired. If the width of the epidural space is more than4mm at the level of L3～L4 intervertebral space, or more than 5 mm at L4～L5, or more than 6 mmat L5 S1, and the sagittal diameter of the dural sac is less than 8mm, the narrow lumbar canal would be considered. All myelographic finings can be classified into 6 types :(1)Wasp waisted type(2) Stump appearance(3)Unilateral indentation(4)Segmental filling defect(5) Joints of a lotus root (6) Columnar stenosi.
