Pseudoaneurysms (PsA) and arteriovenous fistulae (AVF) of the thyrocervical trunk and its branches are rare complications of traumatic or iatrogenic arterial injuries. Most such injuries are iatrogenic and are associated with central venous catheterization. Historically, thyrocervical trunk PsA and AVF have been managed with open surgical repair; however, multiple treatment modalities are now a...

the thyrocervical trunk most commonly arises from the upper portion of the first segment of the subclavian artery, close to the medial edge of the scalenus anterior muscle and after short distance is divided to the inferior thyroid, transverse cervical, and suprascapular artery. this study reports important variations in branches of the thyrocervical trunk in a singular female cadaver. on the r...

This study reports important variations in branches of the subclavian artery in a singular cadaver. The origin of the left vertebral artery was from the aortic arch. On the right side, no thyrocervical trunk was found. The two branches which normally originate from the thyrocervical trunk had a different origin. The transverse cervical artery arose directly from the subclavian artery and supras...

The vertebral artery normally arises from the subclavian artery, and variations in its origin have been described. We describe a unique case of the left vertebral artery arising from the thyrocervical trunk.

OBJECTIVES To study the prevalence of degenerative changes in the arteries supplying the cervicobrachial region, and their relation to cervical disc degeneration. METHODS Fifty postmortem aortic arch angiographies were evaluated for occlusions and variations in the diameter of the vertebral arteries and thyro- and costocervical trunks, as well as for tortuosity, average diameter and the highe...

Rationale Knowledge of the relationship of the dorsal scapular artery (DSA) with the brachial plexus is limited. Objective We report a case of a variant DSA path, and revisit DSA origins and under-investigated relationship with the plexus in cadavers. Methods The DSA was examined in a male patient and 106 cadavers. Results In the case, we observed an unusual DSA compressing the lower plexus tru...
