Summary

What Researchers Did

Researchers reported a case of cerebral air embolism during lung segmentectomy with video-assisted thoracic surgery (VATS) in a 64-year-old woman.

What They Found

They found that a 64-year-old woman undergoing VATS lung segmentectomy experienced a rapid increase in systolic blood pressure from 120 to 170 mmHg and a sudden drop in BIS value from approximately 45 to 5 after air injection to confirm the surgical lesion. This event led to cerebral air embolism, confirmed by imaging, resulting in her discharge with left hemiparalysis on the 11th postoperative day.

Canadian Relevance

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

Study Limitations
