Chylothorax following apparently spontaneous central venous thrombosis in a patient with septic shock.

Within the pediatric age group, chylothorax is rare and has been reported almost exclusively in the setting of thoracic surgical procedures or central venous hypertension secondary to central venous catheter thrombosis. We report on the development of central venous thrombosis and chylothorax in the absence of the usual risk factors in a patient with septic shock, and we expand on the role that procoagulant states, such as those induced by sepsis, might play in the development of this complication. This case reminds the practitioner that central venous thromboses and their complications may occur in the absence of the usually reported risk factors and must therefore still be considered when other clinical events suggest their presence.
