Anatomical textbooks usually cite the thyrocervical trunk, which arises from the first part of the subclavian artery, as the most common origin of the suprascapular artery [1, 2]. Variations concerning the origin of the suprascapular artery are rare but have been documented arising from all three parts of the subclavian artery, the costocervical trunk, the axillary artery, and the internal thor...

INTRODUCTION: The inferior thyroid artery (ITA) usually originates from the thyrocervical trunk in majority of human population (90.5%), or subclavian a few populations humans (7.5%). It is quite rare to find ITA originating common carotid (CCA). CASE PRESENTATION: This study was case report cadaveric dissection at anatomy department, university Rwanda. 54-year-old male who had 2 arteries on le...

An unusual case of left internal thoracic artery (ITA) origin from the thyrocervical trunk (TCT) was detected during routine cadaver dissection. The variability of origin and course of ITA has less or more frequently been documented in the literature. However, the ITA origin from the TCT on the left side has been detected less commonly, making its dissection and preparation during coronary arte...

Superior mediastinum contains many important vessels and tubes, variation of one may affect the other. Left brachiocephalic vein crosses arch of the aorta and its branches superficially. Arch of the aorta from its convex superior aspect usually provides brachiocephalic, left common carotid and left subclavian artery from the right to left. Left subclavian artery continues as axillary artery and...
