Successful treatment of massive hemothorax with class IV shock using aortography with transcatheter embolization of actively bleeding posterior left intercostal arteries after penetrating left chest trauma: A case for the hybrid OR

摘要

Hemothorax is a common occurrence after blunt or penetrating injury to the chest. Posterior intercostal vessel hemorrhage as a cause of major intrathoracic bleeding is an infrequent source of massive bleeding. Selective angiography with trans-catheter embolization may provide a minimally invasive and efficient method of controlling bleeding refractory to surgical treatment. Presentation of case A 19 year-old male sustained a gunshot wound to his left chest with massive hemothorax and refractory hemorrhage. He was emergently taken to the operating room for thoracotomy and was found to have uncontrollable bleeding from the chest due to left posterior intercostal artery transection. The bleeding persisted despite multiple attempts with sutures, clips and various hemostatic agents. Thoracic aortography was undertaken and revealed active bleeding from the left 7th posterior intercostal artery, which was coil-embolized. The patient’s hemodynamic status significantly improved and he was transferred to the intensive care unit. Discussion Posterior intercostal bleeding is a rare cause of massive hemothorax. Bleeding from these arteries may be difficult to control due to limited exposure in that area. Transcatheter-based arterial embolization is a reliable and feasible option for arresting hemorrhage following failed attempts at hemorrhage control from thoracotomy. Conclusion Massive hemothorax from intercostal arterial bleeding is a rare complication after penetrating chest injury (Aoki et al., 2003). Selective, catheter-based embolization is a useful therapeutic option for hemorrhage control and can be expeditiously employed if a hybrid operating room is available.
