Pneumomediastinum after transbronchial cryobiopsy

Area of Science:

• Pulmonology
• Interventional Pulmonology
• Thoracic Surgery

Background:

• Pneumomediastinum is the presence of air within the mediastinum.
• Bronchoscopy is an endoscopic diagnostic tool used in pulmonology.
• Transbronchial cryobiopsy (TBLC) is a minimally invasive lung biopsy technique.

Purpose of the Study:

• To report the first known case of pneumomediastinum following TBLC.
• To raise awareness among interventional pulmonologists about this rare complication.
• To document the clinical course and outcome of TBLC-induced pneumomediastinum.

Main Methods:

• A single case report of a patient who developed pneumomediastinum after TBLC.
• Review of existing literature via PubMed search and systematic reviews.
• Clinical observation of the patient's resolution of pneumomediastinum.

Main Results:

• Pneumomediastinum is a rare complication of bronchoscopy.
• No previous cases of pneumomediastinum following TBLC were found in the literature.
• The reported case of pneumomediastinum after TBLC resolved spontaneously within days without intervention.

Conclusions:

• Transbronchial cryobiopsy (TBLC), while generally safe, can rarely lead to pneumomediastinum.
• Interventional pulmonologists should be aware of this potential complication.
• Spontaneous resolution is a possible outcome for TBLC-associated pneumomediastinum.
