Introduction: The thyroideaima artery is an
inconstant vessel with a highly variable rate of
occurrence and origin. Its course in the superior
mediastinum and lower neck is hazardous in median
surgical approaches to these areas. Thyroideaima is
a rare anomalous artery supplying the thyroid gland
apart from the superior and inferior thyroid arteries.

Case Report: During routine dissection of
embalmed male cadaver approximately 65 yearsold
in the department of the Anatomy at Shri Sathya Sai
Medical College & Research Institute, Ammapettai,
Chennai, this variation was found in thorax region.
Thyroideaima artery arising from arch of aorta.
Clinical importance: It is of surgical importance
in thyroid, parathyroid, tracheal and mediastinal
surgeries.
Conclusion: Thyroideaima artery, although a rare
arterial variation, a thorough regional anatomic
knowledge and meticulous dissection will not only
help us in identifying such a vascular variation, also
help us in preventing an accidental injury.Key words: Thyroideaima; Thyroidectomy;
