The thyroid gland receives blood supply predominantly
from paired superior and inferior thyroid arteries. The superior thyroid
artery originates from external carotid while the inferior thyroid artery
is a branch of thyrocervical trunk. Unusual origins of superior thyroid
artery include common carotid and cervical part of internal carotid
arteries while those for the inferior thyroid artery are subclavian,
common carotid or the vertebral arteries. These origins vary between
populations. Knowledge of variant anatomy of these arteries is
important in surgical procedures within the neck. This study describes
variant origin of the thyroid arteries in a Kenyan population Over 25% of superior thyroid arteries and 11 % of
inferior thyroid arteries show variant origins. The common carotid and
subclavian arteries were the most frequent variant sites of origin for
superior and inferior thyroid arteries respectively. Bilateral asymmetry
was observed. Neck surgeons should be aware of these variations
during ligation and selective embolisation of thyroid arteries to avoid
complications during surgery
