摘要

The branching pattern and the course of brachiocephalic trunk in relation to the trachea, thyroid gland has profound surgicalimportance. Any alteration in the normal course of the brachiocephalic trunk, if accidently ruptured during emergency tracheostomyor thyroid surgeries may lead to haemorrhage. Hence, anomalous course of vessels in the neck and thorax should be kept in mindto prevent iatrogenic injury to abnormal vessels. We present a case with a variable course of brachiocephalic trunk passing left toright transversely crossing trachea in a formalin fxed female cadaver. In this case report, brachiocephalic trunk had its origin fromthe arch of aorta to the left of trachea corresponding to the left margin of manubrium sterni. Then, it ascended along the left marginof trachea up to the lower border of the left lobe of thyroid gland taking a sharp bend of approximately 90° to hook around and crossthe trachea transversely to the right side along the inferior margin of the right lobe of thyroid gland. Knowledge of the variable rathertransverse course of the brachiocephalic trunk appears to be important in various surgical approaches such as tracheostomies,thyroidectomies and mediastinoscopies.
