Superior bronchial artery arising from the left common carotid artery: embryology and clinical considerations.

摘要

A bronchial artery arising from the left common carotid artery was incidentally documented during cerebral angiography in a 64-year-old patient. This variant can be understood as the adult persistence of a primitive bronchial branch arising from the third branchial arch. It represents a potential pitfall for the identification and treatment of the bleeding source in patients with hemoptysis.
