Summary

What Researchers Did

Researchers reported a case of cerebral air embolism resulting from accidental air injection during cerebral angiography.

What They Found

A 60-year-old man experienced posterior circulation ischaemia symptoms after air was accidentally injected via the left subclavian artery, with angiography showing air in the basilar artery. Despite these symptoms, MRI including diffusion-weighted imaging showed no abnormality 4 hours later. The patient received hyperbaric oxygen within 5 hours, and all symptoms resolved completely within a week.

Canadian Relevance

This study has no direct Canadian connection.

Study Limitations

As a single case report, the findings may not be generalizable to all patients experiencing cerebral air embolism.
