Hyparterial bronchus

Last revised by Yuranga Weerakkody on 12 Nov 2022

A hyparterial bronchus refer to any bronchus originating inferior to the level of the pulmonary artery. Conversely, the right superior lobar bronchus can be referred to by its anatomical relationship to the pulmonary arteries as being eparterial.

The term may be encountered in the classification of heterotaxy syndromes, and may be used to differentiate polysplenia (hyparterial bronchus) and asplenia (eparterial bronchus) syndrome.
