Introduction: Blood retained after thoracic drainage for hemothorax undergoes physiological fibrinolysis but for unknown reasons, this fibrinolysis does not always occur. In order to determine the predictive factors for clotting of post-traumatic hemothoraces, we conducted this retrospective study. Patients and Methods: This is a retrospective mono-centric analytical study, carried out over a period of 4 years, involving 52 patients who presented with post-traumatic hemothorax. In view of the persistence after pleural drainage of an opacity on the chest X-ray, a chest CT scan is performed to confirm the diagnosis of the hemothorax. The surgical indication had been made without the need for a second drainage. Results: We identified 26% clotted hemothorax. Blunt chest trauma as a mechanism of occurrence was found in 22 patients (42.3%), while 30 patients (57.7%) were victims of an open chest trauma. The interval between the day of the trauma and the drainage was 5.3 days on average. Video-assisted mini-thoracotomy had been performed in a single patient, while two patients had undergone thoracoscopy and for the remainders patients, surgical approach was a conservative postero-lateral thoracotomy. The statistically significant predictive factors that emerge from our study are, on the one hand, young age but also the average interval between thoracic trauma and thoracic drainage. Conclusion: The predictive factors identified reflect the delay in referral and / or consultation of patients and in particular in young subjects.
