Tension chylothorax in two pediatric patients.
Although the accumulation of gas is the most common cause of an expanding interpleural space, the presence of other structures or substances (hydrothorax, gastrothorax, hemothorax, urohemothorax, pyothorax, and chylothorax) under pressure may be sufficient to cause hemodynamic and respiratory compromise. We present two pediatric patients that developed hemodynamic and respiratory effects secondary to a chylothorax. The first patient presented in respiratory distress and cardiovascular collapse 4 weeks after a Fontan procedure. Placement of a chest tube resulted in the release of chyle under pressure and prompt resolution of hemodynamic and respiratory symptoms. The second patient was a 2100 g neonate who developed a chylothorax during an episode of sepsis following gastroschisis repair. On two separate occasions, the development of the chylothorax was associated with tachycardia, oliguria, and increased requirements during mechanical ventilation. Chest tube placement resulted in the release of chyle under pressure and resolution of the symptoms. These two cases demonstrate that chylothorax like pneumothorax can have deleterious effects on hemodynamic and respiratory function.
