Anomalous origin of left vertebral artery from descending thoracic aorta: A rare variant.

We present a case of a 4-year-old child operated previously for cyanotic congenital heart disease where the follow-up computed tomography (CT) angiography revealed anomalous origin of the left vertebral artery from the descending thoracic aorta. This case also highlights the potential implications of this variant and the value of CT angiography in diagnosing this anomaly.
