The dissection of the intracranial vertebral artery (VAD) is a common cause of young age brain stem stroke. VAD can be detected by conventional angiography, but there is yet no agreement on the most effective tool to use for the detection of VAD. Here, we report a patient with VAD, who was diagnosed with an intimal flap within the left vertebral artery by the magnetic resonance angiography (MRA) source images. Transcranial Doppler (TCD) showed a reversed flow in the basilar artery. After 4 months, TCD and transcranial color-coded Doppler (TCCD) confirmed a normal anterograde flow of the vertebro-basilar arteries.
颅内椎动脉夹层是年轻患者脑干卒中的常见原因。椎动脉夹层可通过传统血管造影检测，但对于检测椎动脉夹层的最有效工具尚无定论。在此，我们报告一名椎动脉夹层患者，其通过磁共振血管造影（MRA）源图像被诊断为左椎动脉内存在内膜瓣。经颅多普勒（TCD）显示基底动脉血流逆转。4个月后，TCD和经颅彩色编码多普勒（TCCD）证实椎基底动脉顺行血流正常。
