Complications of pulmonary resection: postpneumonectomy pulmonary edema and postpneumonectomy syndrome.

Bassed on the authors' review of the unusual variants of PPS and the body of published experience, a revision of the current classification scheme for PPS into a more comprehensive form is justified as follows: (1) by the nature of obstruction; and (2) by the time of onset. This classification encompasses early and late symptom onset, as well as considering both airway and vascular compression. This scheme argues in favor of an expanded cardiac work-up in addition to the measures outlined previously for airway assessment. Althought PPS remains a rare clinical entity, the refinement in the understanding of this condition and the evolution of treatment options have vastly improved patient outcomes. A careful evaluation of the patient must be done before embarking on treatment owing to the numerous etiologies for progressive dyspnea in the pneumonectomy patient.
