Summary
Bilateral phrenic nerve injury after coronary artery bypass surgery is rare. This case highlights prolonged ventilatory support needs and the value of electromyography for diagnosing and predicting outcomes of diaphragm dysfunction.
Area of Science:
- Cardiology
- Thoracic Surgery
- Neurology
Background:
- Phrenic nerve palsy can occur after open-heart surgery, typically unilaterally and asymptomatically.
- Bilateral phrenic nerve injury is an infrequent complication following coronary artery bypass grafting (CABG).
- Diaphragm dysfunction can lead to significant morbidity and prolonged mechanical ventilation.
