| 目的 探讨64层螺旋CT血管成像(CTA)在后循环缺血诊断中的价值。方法 收集临床拟诊为后循环缺血的患者94例,行头颈部CTA,观察椎基底动脉和颈内动脉系统的形态,有无异常分支,有无狭窄。并评价横突孔有无狭窄以及钩椎关节有无增生。结果 94例患者中,51例存在椎基底动脉及颈内动脉系统的各种类型血管结构异常,横突孔狭窄或钩椎关节增生而不伴有血管病变20例,另有椎动脉内支架2例。血管及颈椎骨质情况均未见明显异常的21例。结论 64层螺旋CTA能够同时显示椎基底动脉和颈内动脉的形态、走行、小分支及其侧支循环情况, 以及横突孔和钩椎关节等结构的改变。可以更全面的评价后循环缺血的病因及评估支架成型术后的改变。 |

| Objective To explore the value of 64-slice spiral CT angiography (CTA) in the evaluation of posterior circulation ischemia. Methods Ninety-four patients clinically diagnosed as posterior circulation ischemia underwent head and neck CTA. The shape of vertebrobasilar and carotid artery were evaluated, the size of the transverse process foramen and the degeneration of Luschka joint were analyzed. Results Among the 94 cases, there were 51 cases with various types of vessel structural abnormities in the vertebral basilar artery and internal carotid systems, transverse process foramen narrowing and degeneration of Luschka joint were found in 20 cases without involvement of vessels, and stent was seen in 2 cases. While no abnormalities of vessel and cervical spine were found in 21 cases. Conclusion 64-slice CTA can demonstrate the structure of vertebrobasilar artery and the carotid system, as well as the bony cervical spine in a single CT, it may play an important role in the evaluation of posterior circulation ischemia. |
