  • Context: Anatomical and morphological variations of the aortic arch and its branches are important in relation to thoracic and neck surgery. However, developmental abnormalities of the vertebral arteries are generally considered to be very rare. They have mostly been described in single case reports or small series. Thus, there is a need for further knowledge as an aid in planning surgery on the aortic arch or endovascular interventions. Objective: To report on a case of anomalous origin in the left vertebral artery. Case report: In a male cadaver, a left vertebral artery with its origin in the aortic arch between the left common carotid and left subclavian arteries was observed. Its length was 120 mm, and its diameter was 5.5 mm. It entered the transverse foramen of the third cervical vertebra. Conclusion: Knowledge of the anatomical variation of the origin of the vertebral artery is important not only diagnostically but also in planning surgery on the aortic arch or endovascular interventions.
