Computed tomography (CT)-guided catheter drainage effectively treated lung abscesses in 19 patients with sepsis. This minimally invasive approach achieved a 100% cure rate, avoiding surgery in most cases.

Area of Science:

  • Pulmonology
  • Interventional Radiology

Background:

  • Lung abscesses can lead to sepsis, often requiring aggressive treatment.
  • Standard medical therapy, including antibiotics and bronchoscopy, may fail in some patients.
  • Refractory lung abscesses pose a significant clinical challenge, necessitating alternative interventions.

Purpose of the Study:

  • To evaluate the efficacy and safety of computed tomography (CT)-guided percutaneous catheter drainage for lung abscesses.
  • To determine the success rate of CT-guided drainage in patients with sepsis unresponsive to conventional therapy.
  • To assess the rate of surgical avoidance following CT-guided drainage.

Main Methods:

  • Nineteen patients with sepsis and lung abscesses refractory to standard treatment underwent CT-guided percutaneous catheter drainage.

  • Patients had received at least 5 days of antibiotics, and 11 had undergone bronchoscopy.
  • Catheter placement strategy considered the route through normal lung versus abscess-pleural syndesis.

    • Main Results:

    • All 19 patients (100%) achieved clinical and radiographic cure of the lung abscess.
    • Major surgery was avoided in 16 out of 19 patients (84%).
    • Complications were minimal, including one hemothorax and three minor issues (clogged catheter, transient intracranial pressure elevation).

    Conclusions:

    • CT-guided percutaneous drainage is a highly effective treatment for lung abscesses that do not respond to conventional therapy.
    • This interventional radiology technique can obviate the need for major surgery in the majority of patients.
    • A preferred catheter route involves traversing abscess-pleural syndesis, with CT crucial for planning.
