Summary

Decortication surgery significantly improves lung function and perfusion in chronic pleural empyema patients. Post-surgery, vital capacity and FEV1 improved, with lung perfusion increasing substantially.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Nuclear Medicine

Background:

  • Chronic pleural empyema can lead to significant lung function impairment.
  • Reduced lung perfusion is a common consequence of chronic pleural empyema.

Purpose of the Study:

  • To evaluate the impact of decortication on lung function and perfusion.
  • To assess changes in scintigraphic lung perfusion after decortication.

Main Methods:

  • Functional lung measurements (vital capacity, FEV1) were taken before and after surgery.
  • Scintigraphic lung perfusion scans were performed pre- and post-decortication.
  • The study included 9 patients with chronic pleural empyema.

Main Results:

  • Preoperative average vital capacity was 60% and FEV1 was 65% of predicted values.
  • Affected lung perfusion averaged a 22% reduction pre-surgery.
  • Post-decortication, average vital capacity improved to 78.5% and FEV1 to 79.5%.
  • Lung perfusion increased to a mean of 37.8% after decortication.

    • Conclusions:

    • Decortication leads to significant improvements in lung function parameters.
    • The procedure effectively enhances lung perfusion in patients with chronic pleural empyema.
    • Perfusion scintigraphy is a valuable tool for assessing treatment outcomes.
