LEFT VERTEBRAL ARTERY OF AORTIC ARCH ORIGIN – Ontogeny and Clinical Significance

Dr. Archana Goel, Dr. Naresh Jyoti, Dr. Poonam Delmotra

Abstract :

Accurate knowledge of the normal and variant anatomy of the verteal artery is important for diagnostic angiograhy and surgical procedures in head and neck region and will provide an anatomical basis to assist surgeons in performing safe vascular surgery involving the major anches of this region. Here we are presenting a case report in which left verteal artery(LVA) was taking origin from aortic arch between Left common carotid artery(LCCA) and Left subclavian artery(LSA) instead of arising directly from subclavian artery while on right side, verteal artery was found to be of normal origin. We will discuss incidence, ontogeny and clinical implications in detail related to this anomaly.
