Match each clinical presentation to the most appropriate cardiothoracic surgical diagnosis or traumatic injury.
- A patient presents after severe blunt chest trauma with hypoxia, tachypnea, and patchy, irregular alveolar infiltrates on chest X-ray that are not restricted by anatomical borders.Pulmonary contusion
- A patient involved in a high-speed collision develops sudden respiratory distress, absent unilateral breath sounds, distended neck veins, and tracheal deviation to the contralateral side.Tension pneumothorax
- A patient presents one week after coronary artery bypass grafting with fever, tachycardia, purulent discharge from the sternal incision, and a widened mediastinum on imaging.Acute post-operative mediastinitis
- A patient involved in a rapid deceleration motor vehicle accident presents with a widened mediastinum, obscured aortic knob, and a left-sided hemothorax on chest X-ray.Blunt thoracic aortic injury
Cevap
Properly match the clinical presentations with their corresponding cardiothoracic diagnoses based on injury mechanism, physical exam findings, and radiographic evidence.
Each scenario describes a classic presentation of a major cardiothoracic condition. Patchy infiltrates following blunt trauma suggest a pulmonary contusion. Tracheal deviation and distended neck veins are hallmark signs of a tension pneumothorax. Post-operative fever with sternal drainage indicates acute mediastinitis. Finally, a widened mediastinum with an obscured aortic knob after a deceleration injury strongly points to a blunt thoracic aortic injury.
