What Researchers Did
Researchers reported two cases where asymptomatic intra-arterial air, detected during CT-guided lung needle biopsy, was preventively treated with hyperbaric oxygen therapy (HBOT) using the U.S. Navy Treatment Table (USNTT) 5 protocol.
What They Found
In two cases, a 72-year-old man and a 69-year-old man, asymptomatic intra-arterial air was detected in the left ventricle and other vessels following CT-guided lung needle biopsy. Both patients received preventive HBOT according to the USNTT 5 protocol, with follow-up imaging showing the disappearance of intravascular air after one session in the first case.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada or with Canadian participants.
Study Limitations
The primary limitation of this study is its reliance on only two case reports, which limits the generalizability of the findings.
