Malformation of bronchopulmonary foregut with systemic and pulmonary arterial blood supply.

A case of congenital malformation of the bronchopulmonary foregut with communication between the esophagus and sequestered lobe is reported in a six-month-old boy. Only 29 similar cases have been reported previously, and this case was especially unusual in that the communication was from the middle portion of the esophagus to a right apical sequestration. Another unusual feature was that the sequestered segment was supplied by four systemic arteries from the thoracic aorta, as well as by branches from the right pulmonary artery. Within the sequestration, there was shunting of blood from the systemic to pulmonary arterties with reversal of flow in the pulmonary arterial branches.
