The inferior thyroid artery (branch of the thyrocervical trunk) irrigates the posterior thyroid, including the parathyroid hormones.




Calcium is low while PTH is high. It’s primary hyperparathyroidism (not secondary). Ans is branch of IJV.

mdmofongo  You’re right, how weird. But I guess following the Hx there is no other way to approach it? Not a fair question I would agree. Also the inferior thyroid artery does branch off of the thyrocervical trunk. The superior and middle veins of the thyroids drain into the IJV. +
