Aberrant origin of the inferior thyroid artery from the common carotid artery: a rare anatomical variation.

We describe the case of a rare anatomical variant of the inferior thyroid artery (ITA) taking its origin directly from the common carotid artery (CCA) instead of the thyrocervical trunk (TCT). This anatomical feature exposes to risks of perioperative bleeding and nerve injuries when it is unrecognized by the surgeons. Knowledge of its existence may be helpful to reduce risks for the patient.
