A rare case of traumatic chylothorax after blunt thoracic trauma

Abstract

Introduction. Chylothorax is an accumulation of chyle in the pleural cavity due to a disruption of the thoracic duct. Traumatic chylothoraces are usually a result of a penetrating trauma and disruption of the thoracic duct, but blunt traumatic chylothorax is a rare condition. The aim of this paper is to present a rare case of traumatic chylothorax after blunt thoracic trauma. Case Outline. We present a case of traumatic chylothorax after blunt thoracic trauma in a patient injured in a motor vehicle accident. The patient had a right-sided fracture of rib XI, hydropneumothorax, lung contusion, and signs of pneumomediastinum. We performed thoracic drainage, but a few days later, according to the increase of amount of the fluid daily drained, and the confirmation of laboratory findings of the analyzed fluid, we made a diagnosis of chylothorax and the patient underwent a thoracotomy, where we sutured the thoracic duct. Conclusion. Chylothorax should be considered in patients after chest trauma if they develop a milky pleural effusion. Analysis of pleural fluid and level of triglycerides is important for the diagnosis and treatment of chylothorax.
