Summary
Blunt trauma can cause innominate artery disruption. Early diagnosis via mediastinal widening is crucial for successful surgical repair and preserving cerebral blood flow.
Area of Science:
- Trauma Surgery
- Vascular Surgery
- Emergency Medicine
Background:
- Innominate artery disruption is a rare but severe consequence of blunt chest trauma.
- Mechanisms include sternal compression and rotational forces, leading to potential mediastinal hematoma.
Observation:
- Two patients presented with innominate artery injury following blunt trauma.
- Diagnosis was delayed in one case due to a normal mediastinal shadow, highlighting imaging challenges.
- Successful repair with aortic to subclavian bypass preserved cerebral flow in one patient.
Findings:
- Prompt diagnosis using mediastinal widening aids successful surgical repair.
- Delayed diagnosis, even with intraoperative shunting, may not prevent neurological deficits.
Implications:
- Emphasizes the importance of high clinical suspicion for innominate artery injury in blunt trauma.
- Highlights the need for advanced imaging and surgical techniques to optimize outcomes.
- Suggests potential limitations of temporary shunts in preventing all neurological complications.
