摘　　要：从1991年起,对52例腰椎间盘突出症手术后患者进行CT观察,分析术后CT影像主要分为5类:(1)突起的丰满度(张力)下降(占43.2%);(2)突起形态内致密度下降(21.6%);(3)钙化、骨化和OPLL斑块被切除或部分切除(21.6%);(4)椎板切除与椎间盘手术平面相同(79.7%);(5)与术前者相同形态(13.5%).经随访(平均2年4个月)的摘除髓核后纤维环CT影像,其表现有四:(1)突起低平(32.5%);(2)突起与硬膜囊相连(22.9%);(3)突起完全消失(21.6%);(4)仅有椎间盘膨出改变(22.9%).所有病人的症状体征都消失.作者认为术后近期CT影像不宜作为评价诊疗本病的主要依据,但对远期疗效CT影像仍是一个良好评价手段.Fifty-two cases of post-operative lumbar herniation had been analyzed by CT imaging in which there were mainly five groups of sign: (1)decreased prominance degree of the herniation (43. 2%);(2)decreased density of the herniation(21. 6%) ; (3)calcification,ossification and totally or partly excised OPLL(21. 6%); (4)consistent plane of the protrusion process with the excised laminus (79. 7%);(5)The same post-operative appearance with preoperative configuration(13. 5%). The following signs have been observed by two-years and 4 months following -up after intervetebral disc excision:(1)low and flat process(32. 5%);(2)process connected with the epidural sac (22. 9%); (3)process completely disappeared(21. 6%);(4)disc expansion only(22. 9%). Authors maintain that long-term post-operational CT imaging,should be taken as a dominant basis for evaluation the therapeutic effect of the operation. It is better than that of short term postoperative CT-imaging.
