We present the case of a 38-year-old male who complained of repeated dizziness and syncope. Rotational vertebral artery syndrome (RVAS) was diagnosed via videonystagmoraphy (VNG), computed tomography angiography (CTA) and three-position digital subtraction angiography (DSA). In the neutral position, CTA and DSA revealed left vertebral artery (VA) stenosis at the C2 transverse foramen and right VA hypoplasia. When the head was turned to the right, the blood flow stopped at the C2 level. The bony structure around the VA at the C2 transverse foramen was decompressed via an anterior surgical approach, and the symptoms resolved. This case present the precise stenotic point evaluation by three-position DSA is crucial for the planning of surgical treatment.
我们报告一例38岁男性,其主诉反复头晕和晕厥。通过视频眼震图(VNG)、计算机断层血管造影(CTA)和三位数字减影血管造影(DSA)诊断为旋转椎动脉综合征(RVAS)。在中立位时,CTA和DSA显示C2横突孔处左椎动脉(VA)狭窄以及右VA发育不全。当头部向右侧转动时,C2水平的血流停止。通过前路手术对C2横突孔处VA周围的骨结构进行减压,症状得以缓解。该病例表明三位DSA对手术治疗方案规划的精确狭窄点评估至关重要。
