Pleuroperitoneal shunts in the management of neonatal chylothorax.
Pleuroperitoneal shunts have been placed in five ventilator-dependent newborns with persistent chylothorax. The etiology of the chylothorax appeared to be secondary to superior vena caval obstruction in three patients and was idiopathic in the remaining two. Despite traditional therapies these infants were on a progressively deteriorating clinical course. Hakim-Cordis low-pressure ventricular-peritoneal shunt catheter systems were used in each infant. Ultrasonography was used to follow the regression of pleural effusions and to determine the need for shunt compression. Shunt patency was confirmed with radionuclide studies. Four of five infants had a complete resolution of their chylothorax and pulmonary insufficiency. Three of these infants were extubated within 28 days following the placement of the shunt. Nutritional and metabolic stability was rapidly achieved. The shunts were removed several weeks later without recurrence of the chylothorax. A fifth infant failed to improve after the placement of the pleuroperitoneal shunt and died of progressive pulmonary insufficiency. The placement of pleuroperitoneal shunts in infants with refractory chylothorax is safe, technically easy to perform, and is associated with few complications.
