Computed tomography-guided drainage for large pulmonary bullae.

Area of Science:

• Pulmonology
• Interventional Radiology

Background:

• Large pulmonary emphysematous bullae pose significant therapeutic challenges, particularly in patients with compromised respiratory function.
• Surgical interventions are often not feasible for these patients due to poor surgical candidacy.

Purpose of the Study:

• To evaluate the safety and efficacy of computed tomography (CT)-guided drainage for large pulmonary bullae in inoperable patients.

Main Methods:

• CT-guided drainage was performed in two patients with large pulmonary bullae who were poor surgical candidates.
• The procedure was conducted under local anesthesia and involved catheter insertion for bulla collapse.
• Bronchofiberoptic bronchial occlusion was used to manage prolonged air leak in one case.

Main Results:

• CT-guided bulla drainage was safely and rapidly accomplished in both patients under local anesthesia.
• Sufficient collapse of the pulmonary bullae was achieved in all treated cases.
• Prolonged air leak was successfully managed with bronchofiberoptic bronchial occlusion in one patient.

Conclusions:

• CT-guided bulla drainage is a simple, speedy, and minimally invasive treatment option.
• This method is suitable for inoperable patients suffering from large pulmonary bullae.
• The procedure demonstrates good safety and efficacy in achieving bulla collapse.
