Acute respiratory distress syndrome after peritoneovenous shunt.

A case is presented in which a fatal acute respiratory distress syndrome, associated with disseminated intravascular coagulation, developed immediately after the insertion of a peritoneovenous shunt for management of refractory ascites. The absence of left-sided heart failure or fluid overload was established by (a) lack of diuresis from intravenous furosemide; (b) repeatedly normal pulmonary wedge pressures; and (c) autopsy findings. The nature of the toxic effect of this patient's ascites upon the alveolar membrane remains obscure.
