Abstract:
Background: Thoracic Aortic Injury (TAI) due to penetrating or blunt chest trauma is a critical life-threatening aortic injury. Its diagnosis and treatment always is challenging. An 18-year-old male was admitted due to blunt chest trauma after a high-impact road traffic collision. According to presenting dyspnea, an emergency chest-x-ray revealed left hemothorax for which chest tube was inserted. Hemodynamic monitoring demonstrated uncontrolled hypertension with systolic blood pressure of 200-220 mmHg despite multiple anti-hypertensive drugs. Trans-Thoracic Echocardiography (TTE) revealed abnormal Doppler flow pattern in proximal descending thoracic aorta suggestive for probable coarctation of aorta. Chest CT scan revealed pseudoaneurysm of the descending thoracic aorta just below the isthmus. Due to uncontrolled hypertension, persistent hemothorax and probable aortic pseudoaneurysm presenting as aortic luminal narrowing, surgical resection of the aneurysm was planned. The postoperative course was uneventful and blood pressure normalized without any drugs. Patient is normotensive after 8 years follow up.
