Major arterial supply to cervical oesophagus (LQ)
The 'cervical' oesophagus is supplied by the inferior thyroid artery.
The thoracic oesophagus is supplied by bronchial and oesophageal branches of the thoracic aorta.
Four or five oesophageal branches arise from the anterior surface of the aorta and descend obliquely to the oesophagus, where they form a vascular chain that anastomoses above with the oesophageal branches of the inferior thyroid arteries, and below with ascending branches from the left phrenic and left gastric arteries.
