Anatomical variations in aortic arch (AA) branching are not unusual. Generally, these variations are asymptomatic and are diagnosed incidentally. Here, we report a rare case of a middle-aged female patient with an aberrant right subclavian artery (ARSA) associated with anomalous origins of the bilateral vertebral arteries (VAs).
The patient treated for urolithiasis complained of repeated dizziness for several years.
Echocardiography and computed tomography angiography (CTA) confirmed arterial variations. Moreover, mild stenosis was found in the left common carotid artery (LCCA), which was considered to be the cause of dizziness.
Congenital anomalous arteries were not necessary to intervene urgently, but aspirin and atorvastatin were administered to prevent potential thrombosis attributed to vascular stenosis after completing the operation for urolithiasis.
Whether the symptoms will be alleviated or not should be continuously followed up, and the patient may accept interventional therapy in the future if necessary.
Here, we report the rare variation of AA branches and highlight the importance of preoperative vascular assessment in surgical or interventional procedures for the affected body regions.
主动脉弓（AA）分支的解剖变异并不罕见。通常，这些变异是无症状的，并且是偶然诊断出来的。在此，我们报告了一例罕见的中年女性患者，其右锁骨下动脉（ARSA）异常，并伴有双侧椎动脉（VA）异常起源。
患者因尿路结石接受治疗，反复头晕数年。
超声心动图和计算机断层血管造影（CTA）证实存在动脉变异。此外，还发现左侧颈总动脉（LCCA）存在轻度狭窄，这被认为是头晕的原因。
先天性异常动脉无需紧急干预，但在完成尿路结石手术后，给予阿司匹林和阿托伐他汀以预防潜在的血栓形成。
是否能缓解症状尚需进一步随访，必要时患者可能需要接受介入治疗。
我们报告了 AA 分支的罕见变异，并强调了术前血管评估在受累区域手术或介入治疗中的重要性。
