外伤性脊髓损伤的MRI表现与临床对照分析 总被引:13,自引:0,他引:13
目的评价MRI在脊髓损伤的临床应用价值。资料与方法回顾性分析66例脊髓损伤的临床及MRI表现,着重分析脊髓损伤的MRI征象与病理、临床的关系。结果MRI显示椎体压缩性骨折51例,椎间盘脱出2例,椎体骨折并椎问盘脱出5例;椎体部分性滑脱20例,完全性滑脱1例。显示脊髓完全性截断4例,部分性截断1例,脊髓受压4l例。62例脊髓连贯者59例显示脊髓信号异常。59例有完整的住院治疗记录,治疗后显示病情好转25例,症状无改善26例,死亡8例。结论MRI检查能明确脊髓有无损伤以及损伤的程度,有助于临床治疗措施的选择以及对预后的评估。 相似文献

Objective: To investigate the role of large decompres- sive craniectomy (LDC) in the management of severe and very severe traumatic brain injury (TBI) and compare it with routine decompressive craniectomy (RDC).
Methods: The clinical data of 263 patients with severe TBI (GCS~8) treated by either LDC or RDC in our department were studied retrospectively in this article. One hundred and thirty-five patients with severe TBI, including 54 patients with very severe TBI (GCS ≤ 5), underwent LDC (LDC group). The other 128 patients with severe TBI, including 49 patients with very severe TBI, underwent RDC (RDC group). The treatment outcome and postoperative complications of the two treatment methods were compared and analyzed in a 6-month follow-up period.
Results: Ninety-six patients (71.7 %) obtained satisfactory treatment outcome in the LDC group, while only 75 cases (58.6 %) obtained satisfactory outcome in the RDC group (P〈 0.05). Moreover, the efficacy of LDC in treating very severe TBI was higher than that of RDC (63.0 % vs. 36.7 %, P 〈 0.01). The chance of reoperation due to refractory intracranial pressure (ICP) in the LDC group was significantly lower than that of the RDC group (P 〈 0.05), while the incidences of delayed intracranial hematoma and subdural effusion were significantly higher than those of the RDC group ( P 〈 0.05).
Conclusions: LDC is superior to RDC in improving the treatment outcome of severe TBI, especially the very severe ones. LDC can also efficiently reduce the chances of reoperation due to refractory ICP. However, it increases the incidences of delayed intracranial hematoma and contralateral subdural effusion. 相似文献

Objective: To analyze retrospectively the clinical symptoms, signs, radiological findings and results of treatment of posttraumatic syringomyelia.
Methods: The data of 7 patients with posttraumatic syringomyelia confirmed by computerized tomography (CT) and magnetic resonance imaging (MRI) in our hospital between 1999 and 2004 were reviewed retrospectively. The patients underwent decompressive laminectomy or syringo-subarachnoid (S-S) shunting with microsurgery. Long-term follow-up was available (range: 13-65 months).
Results: The major dinical manifestations of posttraumatic syringomyelia usually included the onset of increasing signs and the development of new symptoms after an apparently stable period. The clinical symptoms included pain, sensory disturbance, weakness, and problems in autonomic nerves. Syrinx existed merely at the cervical level in 4 cases and extended downward to the thoracic levels in the other 3 cases. One case underwent decompressive laminectomy, 6 cases were treated by S-S shunting. During the early postoperative period, all the patients showed an improvement of symptoms of syrinx without major complication or death. The decreased size or collapse of the syrinx was demonstrated by postoperative MRI.
Conclusions : Posttraumatic syringomyelia is a disabling sequela of spinal cord injury, developing months to years after spinal injury. MRI is the standard diagnostic technique for syringomyelia. The patients with posttraunmtic syringomyelia combined with progressive neurological deterioration should be treated with operations. S-S shunting procedure is effective in some patients with posttraumatic syringomyelia. Decompressive procedure may be an alternative primary surgical treatment for patients with kyphosis and cord compression. 相似文献
