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.

Pulmonary edema and continuous positive pressure breathing (CPPB).

We have successfully treated severe pulmonary edema of various etiologies and the concomitant hypoxia in 17 infants and children with continuous positive pressure spontaneous breathing. The pressure used was 8 to 14 cm of water above atmospheric pressure. No significant changes occurred in arterial or central venous blood pressure, and no patient developed clinical evidence of peripheral venous engorgement. Pulmonary edema cleared within 24 hours in all cases. We believe this rapid clearing may differentiate pulmonary edema from pneumonia and pulmonary hemorrhage. The pathophysiology and the roentgenologic findings are presented.
