脊髓型颈椎病脊髓前动脉CT血管造影观察

目的通过颈脊髓前动脉CT血管造影观察脊髓型颈椎病患者的颈脊髓前动脉。方法 2009年2月~2012年8月,采用64排螺旋CT机对17例脊髓型颈椎病患者行脊髓前动脉造影,观察脊髓前动脉阻塞和梗阻,以及MRI T2高信号与脊髓前动脉的关系。结果 2例脊髓型颈椎病并发脊髓前动脉综合征患者脊髓前动脉造影显示颈脊髓前动脉于病变部位中断;其余15例脊髓型颈椎病患者CT脊髓前动脉造影均显影,未见明显中断。结论 64排CT脊髓前动脉造影术可以显像脊髓型颈椎病的颈脊髓前动脉。脊髓型颈椎病脊髓前动脉不易被压迫中断。脊髓型颈椎病MRI图像T2高信号与颈脊髓前动脉无直接关系。

CT angiography of anterior spinal artery in patients with cervical spondylotic myelopathy

Objective To observe the infarct of anterior spinal artery (ASA) in patients with cervical spondylotic myelopathy(CSM) through ASA CT angiography(CTA).Methods From February 2009 to August 2012, 17 CSM patients were performed ASA spinal artery with 64 slices spiral CT to observe anterior spinal ASA with high signal intensity area in T2WI.Results The ASA infarct was found in the lesion area in 2 cases of CSM combine with ASA syndrome patients, while the ASA did not show the obviously interrupt for the other 15 cases of CSM patients.Conclusion The 64-row CT angiography of ASA can identify the ASA of CSM patients. The ASA cannot be easily infarct in the CSM even with severe compression. The high signal area of the MRI T2 phase in the CSM patients has no direct relationship with ASA.
