Dyspnea after pneumonectomy: the result of an atrial septal defect.

We report the case of severe hypoxemia attributable to right-to-left shunting through an atrial septal defect after right-sided pneumonectomy that developed in a 70-year-old man. Normal right atrial and pulmonary artery pressures were measured. Right-to-left shunting through a patent foramen ovale is known as a rare complication after pneumonectomy.

Conservative management of a broncho-oesophageal fistula in a patient with non-Hodgkin's lymphoma.

We describe the case of a 56-year-old male patient with a 2-year history of productive cough and weight loss. The diagnosis of a broncho-oesophageal fistula due to a low-grade Non-Hodgkin's lymphoma was made. The patient was referred for surgical closure of the fistula and resection of the left lower lobe because of intractable severe pneumonia.
