目的：提高对腰椎间静脉压迫症的认识和诊断。材料与方法：笔者总结分析了２９例经手术证实的腰椎间静脉压迫症的ＣＴ表现。结果：压迫部位远侧的腰椎间静脉和前椎内静脉丛呈扩张或曲张的血管影，好发于Ｌ４～５和Ｌ５Ｓ１平面的硬膜囊前、侧方和椎间孔内，分为环形、条形和混合型三种，直径为３～５ｍｍ，其密度略高于硬膜囊和脱出髓核的密度，ＣＴ值为６０～７０ＨＵ。结论：腰椎间静脉压迫症临床上难以做出确切诊断，ＣＴ是诊断本病的主要方法
Objective: To improve understanding and diagnosis of lumbar intervertebral venous compression. Materials and Methods: The author summarizes the CT findings of 29 cases of confirmed lumbar intervertebral venous compression. Results: The lumbar intervertebral vein and anterior intervertebral venous plexus distal to the compression site showed dilation or varicose veins, which occurred in the anterior, lateral and intervertebral foramen of L4-5 and L5S1 planes and was divided into annular , Bar and hybrid three, a diameter of 3 ~ 5mm, its density is slightly higher than the dural sac and prolapse nucleus density, CT value of 60 ~ 70HU. Conclusion: The clinical diagnosis of lumbar intervertebral venous compression is difficult to make accurate diagnosis, CT is the main method of diagnosis of the disease
