Abstract
With recent increase in the use of CT, MRI and Angiography, it has been pointed out that an accurate understanding of morphology of thyrocervical trunk and detailed information about thyrocervical trunk are essential pre‐requisites for accurate diagnosis. Four Present study was aimed to conduct anatomical study of thyrocervical trunk and its variations. Present study was prospective, observational study, conducted in cadavers in Department of Anatomy. Thyrocervical trunk dissected and exposed according to methods described in Cunningham’s manual of practical Anatomy. In present study, out of 60 cadavers examined 57 (95%) were male and 3 (5%) were female. Thyrocervical trunk was not present on right side in 5 cases (11.9%) In 98.33% left internal thoracic artery was originating from first part of subclavian artery, 1.66% was originating from thyrocervical trunk (TCT) Out of 60 cadavers, in 91.66% of cases the right inferior thyroid artery had its origin from thyrocervical trunk itself. In 8.33% of cases. Right Inferior thyroid artery had its origin directly from the first part of Subclavian artery, Right suprascapular artery had its origin from thyrocervical trunk in 85% of cases, origin from the first part of subclavian artery from a common trunk in 6.66%, not present in 5% of cases, origin from third part in 1.66% of cases and origin from right dorsal scapular artery in 1.66% of cases. Left suprascapular artery had its origin from Thyrocervical trunk in 96.66% of cases, from third part of subclavian artery in 1.66% of cases and in1.66% cases origin from left dorsal scapular artery. Present study showed clinically significant variations as, internal thoracic artery from thyrocervical trunk, Inferior thyroid artery separately from first part of subclavian artery, absence of suprascapular artery and variant origin of dorsal scapular, suprascapular arteries and costocervical trunk.
