In chronic pulmonary emboli, lung perfusion may be maintained by either recanalization of occluded pulmonary artery segments or collateral bronchial circulation. We present a case of noncardiogenic pulmonary edema superimposed on chronic pulmonary emboli, in which the occluded segments of lung were spared from pulmonary edema, but not from neutrophil infiltration. This case demonstrates that ch...

We do not think there is much debate to this opinion piece. Several studies using healthy human subjects (2, 4, 5, 7) demonstrate evidence of pulmonary edema from sea-level exercise. In a recent review (6), 51 of 78 sub...
