CT椎间盘造影诊断腰椎间盘突出症 总被引:17,自引:1,他引:16
73例临床疑诊为腰椎间盘突出症的患者作了脊髓造影和CT椎间盘造影检查。手术治疗53例,其中突出45例51个间隙。两种方法的阳性率分别为70%和92%。CT椎间盘造影影像能清晰显示突出物的大小、部位,硬膜囊神经根受压、造影剂充填、关节突退变情况。当其它辅助检查仍不能明确定性和定位诊断时,CT椎间盘造影可帮助确诊,尤其对L_5-S_1椎间盘突出意义更大。 相似文献

An association between progression of cervical disc degeneration and that of lumbar disc degeneration has been considered
to exist. To date, however, this association has not yet been adequately studied. Age-related changes in the cervical intervertebral
discs were evaluated by magnetic resonance imaging (MRI) in patients with lumbar disc herniation, and compared with the MRI
findings of healthy volunteers without lower back pain. The purpose of this study was to clarify whether the prevalence of
asymptomatic cervical disc degeneration is higher in patients with lumbar disc herniation than in healthy volunteers. The
study was conducted on 51 patients who were diagnosed as having lumbar disc herniation and underwent cervical spine MRI. The
patients consisted of 34 males and 17 females ranging in age from 21–83 years (mean 46.9 ± 14.5 years) at the time of the
study. The control group was composed of 113 healthy volunteers (70 males and 43 females) aged 24–77 years (mean 48.9 ± 14.7 years),
without neck pain or low back pain. The percentage of subjects with degenerative changes in the cervical discs was 98.0% in
the lumbar disc herniation group and 88.5% in the control group (p = 0.034). The presence of lumbar disc herniation was associated significantly with decrease in signal intensity of intervertebral
disc and posterior disc protrusion in the cervical spine. None of the MRI findings was significantly associated with the gender,
smoking, sports activities, or BMI. As compared to healthy volunteers, patients with lumbar disc herniation showed a higher
prevalence of decrease in signal intensity of intervertebral disc and posterior disc protrusion on MRI of the cervical spine.
The result of this study suggests that disc degeneration appears to be a systemic phenomenon. 相似文献

Background:
Large lumbar disc herniation (LDH) has been reported to have a greater tendency to resolve in clinical and pathomorphological evolutions. However, various definitions of large LDH have been used without validation, and the clinical symptoms of large LDH have not been fully elucidated. We conducted a retrospective analysis to determine the clinical characteristics and treatment outcome of massive LDH with complete dural sac stenosisMaterials and Methods:
We retrospectively reviewed 33 cases of LDH with complete dural sac stenosis on magnetic resonance imaging. Complete dural sac stenosis was defined as no recognizable rootlet and cerebrospinal fluid signal on T2-weighed axial MR images. The clinical outcome parameters included back pain, leg pain, Oswestry disability index (ODI), and neurological dysfunction. The paired t-test and Wilcoxon''s signed rank test were used to compare serial changes in back pain, leg pain and neurological dysfunction.Results:
Mean duration of followup was 66 months (range 24 - 108 months). There were 24 male and 9 female. The mean age was 37 years (range 20 - 53 years). At presentation, mean visual analogue scales for back pain and leg pain were 75.3 ± 19.1 (range 12 - 100) and 80.2 ± 14.6 (range 0 -100), respectively. Mean ODI was 67.1 ± 18.8 (range 26 - 88). Neurological dysfunction was found in 9 patients (27.3%), and the bowel/bladder dysfunction was found in 2 patients (3.1%). Conservative treatment was performed in 21 patients (63.6%) with satisfactory results. Seven patients underwent decompressive surgery, and 5 underwent posterolateral fusion.Conclusions:
A massive LDH with complete dural sac stenosis was found to be associated with severe back and leg pain at presentation, however surgical treatment can be deferred unless significant neurological symptoms occur. 相似文献18.

Intradural or intraradicular lumbar disc herniation (IDH) is a relatively rare condition often diagnosed intraoperatively. We encountered an extreme variant of IDH - a transradicular herniation as the disc material extruded through the lumbar nerve root through a split essentially transecting the nerve root. While failure to recognize intradural and intraradicular disc herniation can lead to failed back surgery, the variant described in the present case could lead to iatrogenic injury and complication if not recognized. A unique case of transradicular lumbar disc herniation in a 25-year-old patient is presented with the depiction of intraoperative images supplementing the text. 相似文献
