Upper third
This part of the esophagus is supplied by branches of the inferior thyroid arteries. The anterior cervical esophageal arteries give twiglike branches to both esophagus and trachea. Accessory arteries to the cervical esophagus derive frequently from the subclavian, common carotid, vertebral, ascending pharyngeal, superficial cervical and costocervical trunk.
Middle third
This part of the esophagus is supplied by the right sided intercostals and bronchial arteries (ie, esophageal branches of vessels arising directly from the aorta).
Lower third
This part of the esophagus is supplied by the ascending branches of the left gastric (cardio-esophageal branches), and left inferior phrenic artery.
