What Researchers Did
Researchers reported a case of systemic arterial air embolism following CT-guided lung tumour 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 tumour 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.
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.
