To report an extremely rare vertebral artery (VA) origin configuration.
Angiographic and MRI features of a VA triplication in a child are presented.
The VA trifurcation was the result of the simultaneous persistence of the 4th, 5th and 6th primitive cervical intersegmental arteries, respectively, reaching the transverse canal at C4, C5 and C6. A contralateral VA duplication was noted as well.
A previously undocumented instance of VA triplication is presented. Knowledge of such variations is important for the planning of diagnostic and therapeutic cervicocranial angiography and the understanding of unusual images on noninvasive imaging studies. This type of anomaly also represents a risk factor for arterial dissection.
报告一种极其罕见的椎动脉(VA)起源构型。
呈现一名儿童椎动脉三重分支的血管造影和磁共振成像(MRI)特征。
椎动脉三叉分支是第4、5和6条原始颈节段间动脉分别同时持续存在并到达C4、C5和C6横突孔的结果。同时还发现对侧椎动脉双分支。
呈现了一例此前未记录的椎动脉三重分支病例。了解此类变异对于诊断性和治疗性颈颅血管造影的规划以及理解无创成像研究中的异常图像很重要。这种类型的异常也是动脉夹层的一个危险因素。
