Autologous blood patch in persistent air leaks after pulmonary resection

Area of Science:

• Thoracic surgery
• Pulmonary medicine
• Surgical complications

Background:

• Persistent air leak is a frequent complication post-pulmonary resection.
• This complication leads to extended hospitalization and increased medical costs.
• Current treatment strategies lack a definitive consensus.

Purpose of the Study:

• To evaluate the efficacy and safety of autologous blood patch pleurodesis for persistent air leaks.
• To assess the success rate and impact on hospital stay.
• To determine the feasibility of this treatment in patients with fixed pleural space deficits.

Main Methods:

• A 7-year retrospective study of 21 patients undergoing pulmonary resection with persistent air leaks.
• Treatment involved injecting autologous blood (50-150 mL) into the chest tube.
• Air leaks were classified, and chest radiographs assessed for pleural space deficits.

Main Results:

• A 4% incidence of persistent air leaks was observed.
• The autologous blood patch achieved a 100% success rate, with resolution within 24 hours in 81% of cases.
• Mean hospital stay was reduced to 15 days.

Conclusions:

• Autologous blood patch pleurodesis is a well-tolerated, safe, and cost-effective treatment.
• It demonstrates high efficacy in resolving postoperative persistent air leaks.
• The procedure is effective even with associated fixed pleural space deficits.
