Summary
Cerebral air embolism is a rare complication of lung biopsies. Prompt hyperbaric oxygen therapy can lead to full recovery from neurological deficits.
Area of Science:
- Neurology
- Pulmonology
- Interventional Radiology
Background:
- Percutaneous transthoracic fine needle aspiration (PTFNA) is a common diagnostic procedure for lung lesions.
- While generally safe, PTFNA carries potential risks, including rare but serious complications like cerebral air embolism.
Observation:
- A case report details a patient who developed left-sided hemiplegia following PTFNA of a right lung tumor using a 0.6 mm needle.
- The neurological deficit was attributed to a probable air embolism in the right middle cerebral artery.
Findings:
- The patient experienced acute paralysis of the left upper and lower extremities.
- Imaging or diagnostic confirmation of the air embolism was not explicitly detailed, but the clinical presentation strongly suggested this diagnosis.
Implications:
- This case highlights the importance of recognizing cerebral air embolism as a potential complication of PTFNA.
- Early diagnosis and prompt intervention with hyperbaric oxygen therapy (HBOT) are crucial for favorable patient outcomes.
- Consideration of needle size and technique may be relevant in minimizing embolic risk during PTFNA.
