Lack of inferior thyroid artery.
In the present study, a case of a cadaver is reported in which variations of some branches of both subclavian arteries occur. Among the most impressive findings is the lack of the right inferior thyroid artery combined with an abnormal ramification of the right superior thyroid artery, the terrace-like course of the left inferior thyroid artery and variations in the course of the prevertebral segment of both vertebral arteries with a high entry into the transverse cervical foramen of one of them. A morphometric description of the arterial variations has been carried out and their possible significance for the surgical and diagnostic practice is outlined.
