Abstract
Chylothorax, the presence of lymph in the pleural cavity, is asignificant post-cardiac surgery complication. Historically linked to left internal mammary artery (LIMA) harvesting, its occurrence in cases without LIMA usage is uncommon. This paper details a case of chylothorax in an 84-year-old female patient who underwent coronary artery bypass grafting (CABG) without LIMA harvesting. Three months post-surgery, she manifested symptoms of exertional shortness of breath and diminished breath sounds on the left side. Diagnostic measures, including echocardiography and chest X-rays, revealed a pronounced left-sided pleural effusion. Diagnostic thoracocentesis yielded a milky fluid, and laboratory analysis confirmed its chylous nature. Therapeutic interventions comprised chest tube insertion, drainage of the milky fluid, dietary modifications, and the performance of talc pleurodesis after a fatty food-provocation test resulted in increased fluid collection. The patient's journey highlights the challenges of diagnosing and managing post-cardiosurgical chylothorax. The paper emphasizes the importance of early detection and appropriate interventions to prevent complications associated with a heightened mortality risk.
