Summary
Chylothorax, a rare complication after coronary artery bypass grafting, can be successfully treated nonoperatively. This involves pleural drainage and a low-fat diet to resolve chylous leaks.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Gastroenterology
Background:
- Coronary artery bypass grafting (CABG) is a common surgical procedure.
- Chylothorax, characterized by chyle accumulation in the pleural space, is a rare but serious complication post-CABG.
- Internal mammary artery (IMA) harvesting is frequently employed in CABG procedures.
Observation:
- Two cases of left-sided chylothorax are presented following CABG.
- Chylothorax developed at different intervals post-surgery: one week and 14 days.
- Both patients had undergone IMA graft harvesting as part of their CABG.
Findings:
- Nonoperative management was initiated for both patients.
- Therapeutic strategies included adequate pleural fluid drainage.
- A specialized low-fat diet was implemented to reduce chyle production.
Implications:
- Nonoperative treatment can effectively resolve chylothorax post-CABG.
- This approach offers a less invasive alternative to surgical intervention.
- Early diagnosis and management are crucial for favorable outcomes in chylothorax patients.
