Summary

What Researchers Did

Researchers reported a case of cerebral arterial gas embolism (CAGE) in a 75-year-old male following bubble contrast echocardiography, confirmed by computed tomography.

What They Found

A 75-year-old male developed acute stroke symptoms after bubble contrast echocardiography, with emergent computed tomography revealing cerebral arterial gas embolism (CAGE) in the left middle cerebral artery. This case was the first reported instance of radiologically proven CAGE from bubble contrast echocardiography, and the patient achieved substantial recovery after immediate treatment with 100% oxygen and hyperbaric oxygen.

Canadian Relevance

This study has no direct Canadian connection as it is a case report from outside Canada.

Study Limitations

As a single case report, the findings of this study are limited in their generalizability to a broader patient population.
