Summary
Percutaneous aspiration with contrast media instillation aids diagnosis of lung lesions. This method achieved a 92% diagnostic rate, assisting biopsy and lavage for lung abscesses.
Area of Science:
- Pulmonology
- Interventional Radiology
Background:
- Cavitating lung lesions pose diagnostic challenges.
- Percutaneous aspiration is a common diagnostic tool.
Purpose of the Study:
- To evaluate the utility of percutaneous aspiration combined with contrast media instillation for diagnosing cavitating lung lesions.
- To assess the diagnostic yield and therapeutic potential of this combined technique.
Main Methods:
- Twelve patients with cavitating lung lesions of uncertain etiology underwent percutaneous aspiration.
- Radiographic contrast media was instilled into the lung cavities.
- Biopsy of the cavity wall and lavage were performed.
Main Results:
- A diagnosis was established in 11 out of 12 patients (92% diagnostic rate).
- Positive cultures were obtained in 89% of infected cavities.
- The procedure facilitated biopsy, lavage, and sputum expectoration.
Conclusions:
- Percutaneous aspiration with contrast media instillation is a highly effective method for diagnosing cavitating lung lesions.
- This technique offers both diagnostic and potential therapeutic benefits in managing lung abscesses.
