自发性颈部动脉夹层是青年人脑卒中的重要原因之一,其造成的临床表现多变。侵入性血管造影一直被认为是诊断颈部动脉夹层的金标准,但MR血管造影和CT血管造影(CTA)越来越多的被用作非侵入性检查的替代。256排CTA具有薄层、快速、高分辨的特点,联合全脑范围的CT灌注扫描(CTP)可以对颈部动脉夹层患者进行快速诊断,并评估脑血流灌注情况,指导临床选择合适治疗方法。现就256排CTA在自发性颈部动脉夹层中的应用价值进行综述。
Spontaneous dissection of the neck artery is one of the major causes of stroke in young people, which causes variable clinical manifestations. Invasive angiography has long been considered the gold standard for the diagnosis of cervical artery dissections, but MR angiography and CT angiography (CTA) are increasingly being used as alternatives to noninvasive examinations. The 256-row CTA has the characteristics of thin, fast and high resolution. Combined with whole-brain CT perfusion scan (CTP), it can be used to rapidly diagnose the patients with cervical artery dissection and to evaluate the cerebral perfusion and guide the clinical choice of appropriate treatment . Now 256 row CTA in the application of spontaneous dissection of the neck artery are reviewed.
