Transthoracic lung punctures (TLP) were employed in 13 patients to define etiologic diagnoses of pneumonia complicating severe underlying diseases and proved useful in the resolution of seven of these diagnostic and therapeutic dilemmas. Positive lung punctures provided the only available etiologic information in two instances, and amplified or confirmed information derived from other sources in five additional cases.
Four episodes of pneumothorax occurred in this series of 18 punctures. The potential complications of hemorrhage, empyema or air embolism did not occur in this series.
The literature concerning diagnostic transthoracic lung puncture was briefly reviewed. This technique deserves re-evaluation and further exploration in view of recent changes in the patterns of infections among patients at special risk from recurrent pneumonic infections with uncommon and antimicrobial-resistant microorganisms.
