Differential Diagnosis for Left-Side Chest Pain 2 Days Post CABG

Single Most Likely Diagnosis

  • Pleural effusion: This is a common complication post-cardiac surgery, including CABG. The pain is typically sharp and can be unilateral, depending on the location and size of the effusion. Given the recent surgical history, this diagnosis is highly plausible.

Other Likely Diagnoses

  • Pericarditis: Post-pericardiotomy syndrome is a recognized complication after cardiac surgery, which can present with chest pain, fever, and pericardial friction rub. The pain can be sharp and may improve with sitting up and leaning forward.
  • Pneumothorax: Although less common, pneumothorax can occur post-operatively, especially if there were any complications during the surgery that involved the lungs or pleura. The pain is typically sharp and worsens with deep breathing.
  • Wound infection or hematoma: Early signs of infection or a developing hematoma at the surgical site can cause localized pain and discomfort. While not exclusively chest pain, it can radiate or be referred to the chest area.

Do Not Miss Diagnoses

  • Graft occlusion or myocardial infarction: Although less likely given the early post-operative period, any chest pain post-CABG warrants consideration of graft occlusion or myocardial infarction due to the potential for severe consequences if missed.
  • Pulmonary embolism: This is a critical diagnosis to consider in any post-operative patient with chest pain, as immobility and the surgical procedure itself increase the risk of venous thromboembolism.
  • Aortic dissection: While rare, this is a catastrophic complication that can occur post-CABG, especially if there were any manipulations of the aorta during surgery. Severe, tearing chest pain is characteristic.

Rare Diagnoses

  • Esophageal rupture or perforation: This could occur due to instrumentation during surgery or post-operative nausea and vomiting leading to increased abdominal pressure.
  • Costochondritis: Inflammation of the costochondral junctions can cause sharp chest pain, though it's less likely in the immediate post-operative period following CABG.
  • Pneumonia: Post-operative pneumonia can cause chest pain, especially if it involves the pleura. However, it might be less common to present solely with chest pain without other respiratory symptoms in the early post-operative period.
