Relation between bronchial and pulmonary artery anatomy in heterotaxy
Relation between bronchial and pulmonary artery anatomy in heterotaxy
Anatomy of the relationship of bronchi to pulmonary arteries. (A) Normal: Anterior view with a right mainstem bronchus to its first branch (right upper lobar bronchi) located above the right pulmonary artery (eparterial bronchus), whereas the left bronchus has a longer course from the carina to its first branch point below the left pulmonary artery (hyparterial bronchus). (B) Right atrial isomerism: Anterior view with bilateral short eparterial bronchi with pulmonary arterial branches located anterior to bronchi. (C) Left atrial isomerism: Anterior view of bilateral long hyparterial bronchi. (D) Left atrial isomerism (posterior): Posterior view with pulmonary arteries superior to bronchi.
