[Abnormal course of the right common carotid artery. Anatomic presentation of a case report].
In a woman's cadaver, anatomical dissection reveals that the right common carotid artery follows an irregular course. Namely, after being directed towards the left lobe of the thyroid gland, it surrounds the latter in form of collar in close connection with its lower and right surfaces. In this way, trachea is almost completely covered from the front by this artery. The most probable cause of this anomaly may be a disproportional elongation of the ascending aorta during embryonic life of this woman. This hypothesis is corroborated by the fact that other arteries of this woman (thoracic aorta and common iliac artery) are also disproportionally elongated, in conjunction with the assessment of a greater caliber of all her large arteries.
