The esophageal branches originate from the inferior thyroid artery as it ascends in the neck.


From their origin, the esophageal branches travel medially to reach the esophagus. The then branches descend along the length of the esophagus in the neck.


The esophageal branches of inferior thyroid artery give off ascending and descending branches that anastomose with each other across the midline (Moore, Dalley and Agur, 2013). In addition, the branches anastomose with the esophageal branches of the thoracic aorta which surround the esophagus.

Supplied Structures

The esophageal branches of the inferior thyroid artery supply the esophagus in the neck.

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
