Summary

What Researchers Did

Researchers reported a case of transient, severe sensorineural hearing loss in a 26-year-old woman following angiography with iopamidol.

What They Found

The patient experienced immediate, severe sensorineural hearing loss in both ears (no ABR response at 105 dB) after a second injection of iopamidol during vertebral angiography. Her hearing fortunately recovered to a normal conversation level within 24 hours, with the transient loss attributed to cochlear anoxia lasting 10-20 minutes.

Canadian Relevance

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

Study Limitations

As a single case report, the findings cannot be generalized to a broader patient population.
