Life-threatening chylothorax after left internal mammary artery dissection: therapeutic considerations

Persistent chylothorax developed in a 53-year-old man after left internal mammary artery (LIMA) takedown and required surgical intervention. After an unsuccessful supraclavicular approach, left-sided standard thoracotomy showed thick adhesions around the LIMA takeoff with a diffuse oozing rather than an identifiable discrete leak. A possible leaking point was stitched, the area was sealed with fibrin adhesive, and complete remission ensued. Operation for chylothorax after LIMA takedown is challenging. A left-sided standard thoracotomy with minimal dissection and use of fibrin adhesive rather than blind stitching are recommended.
