A 71 year-old patient with a past medical history of hypertension, percutaneous transluminal coronary angioplasty 7 years ago, and robotic coronary artery bypass grafting of the left internal mammary artery to the left anterior descending artery 9 years ago presents with worsening dyspnea on exertion. He had a biopsy of the upper lobe of the left lung the week before. He was having a neoplastic mass evaluated. The patient presents with a soft left-sided anterior chest mass, inflating and deflating with respiration.
Vital signs: Respiratory rate 25 breaths/min, oxygen saturation 96% on room air; remaining vital signs within normal limits
General: Resting comfortably
Chest: Soft mass expanding and retracting above the left nipple
Labs within normal limits
This is an iatrogenic anterior chest wall lung herniation as a sequela of robotic coronary artery bypass grafting. This was chronic and unrelated to the patient presentation. The patient presented with dyspnea that was actually caused by another iatrogenic complication — pneumothorax from lung biopsy.
Lung herniation can be a rare complication in minimally invasive cardiothoracic surgery.
