Autopsy in sudden cardiac death reveals anomalous left vertebral artery arising from the aortic arch.
Why the study?
The aortic origin of the left vertebral artery is an unusual branching pattern with important implications for surgical, interventional procedures, and sudden cardiac death evaluation.
Case Report (n=1)
This case report highlights an unusual branching pattern of the left vertebral artery originating from the aortic arch, which is important anatomical knowledge for surgical and interventional procedures.
Alerts to rare left vertebral artery arch origin for procedural planning; extends vascular anatomy data yet leaves clinical significance open.
The present paper describes a 53-year-old male who presented to the emergency department with a history of sudden chest pain followed by unconsciousness at home. The autopsy revealed the left vertebral artery (LVA)'s aberrant origin from the aortic arch between the left common carotid artery and subclavian artery in a male deceased during a medicolegal autopsy. The aortic origin of the vertebral artery is an unusual branching pattern. Knowledge about the vertebral artery's normal and variant arterial anatomy is essential for patients who undergo various surgical or interventional procedures. In the sudden death of cardiac origin, its anatomy and morphology also hold crucial value. Typically, the LVA arises from the first part of the left subclavian artery (LSA).

Sonwani et al. (2023) conducted a case report in Aberrant origin of the left vertebral artery (n=1). Aberrant origin of the left vertebral artery was evaluated on Anatomical variation identified during autopsy. Autopsy of a 53-year-old male who died of sudden cardiac death revealed an unusual origin of the left vertebral artery directly from the aortic arch.
