What Researchers Did
Researchers reported a case of systemic arterial air embolism following CT-guided lung tumor marking and its successful treatment with hyperbaric oxygen therapy.
What They Found
A 79-year-old man developed systemic arterial air embolism, losing consciousness and experiencing complete atrio-ventricular block, almost immediately after CT-guided lung tumor marking. Brain CT showed intravascular air bubbles, and while consciousness recovered in 2 hours, left hemiplegia persisted until resolving after 3 episodes of hyperbaric oxygen therapy.
What This Means for Canadian Patients
Canadian patients undergoing CT-guided lung tumor marking should be aware of the rare but potentially fatal risk of systemic arterial air embolism. Prompt recognition and immediate arrangement for hyperbaric oxygen therapy could be crucial for recovery from neurological deficits if this complication occurs.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in Japan.
Study Limitations
The primary limitation of this study is its nature as a single case report, which limits the generalizability of its findings to a broader patient population.
