摘要
目的:探讨腰椎间盘突出症在CTD影像的表现及其临床意义。方法:作椎间盘造影后追加CT扫描,观察椎间盘病变形态、纤维环破裂部位、髓核突出走向并将CTD与临床对比。结果:72例中显像不清3例;椎间盘突出像分3型,退变分4度;纤维环的破裂大多发生在后中央区(73.9％),髓核从后中央途径突出后62％再发生偏移;术中所见髓核突出状况与CTD提示符合率74.2％,CTD1、2型分别相当膨隆型和突出型,3型多为游离型;临床症状与髓核突出后位置有关。结论:CTD能从水平面详细显示椎间盘的局部细微病变,为腰椎间盘突出症的诊断和治疗方法的选择提供确切依据。
Objective: To discuss the CT - discography (CTD) expression of lumbar disc herniation and its clinical significance. Methods: Discograhpy is supplemented by CT scanning in order to observe the morphology of the lesion in the disc, the location of rupture of annulus fibrosus, the trend of nucleus pulposus prolapse and the comparison between the images and the clinical findings. Results: In 3 of the 72 cases, the image is not clear. The herniated nucleus pulposus images can be divided into 3 types, and the disc degeneration into 4 grades. Most of the reptures of annulus fibrosus occur in the posterior central area (73.9%), and lateral displacement is seen in 62% following protrusion of nucleus pulposus. In 74.2% of the cases, CTD suggestions agree with the surgical findings of protrusion of nucleus pulposus. Type 1 corresponds to the protruded type and type 2 corresponds to the extruded type, while type 3 mostly corresponds to the sequestered type. Clinical symptoms are related to the position after protrusion of nucleus pulposus. Conclusion: CTD can horizontally display the details of minute topical lesions in the disc and provided definite evidence for the diagnosis and treatment of lumbar disc herniation.
