Summary
Air embolism during central venous catheter insertion can cause neurological issues. This case highlights a rare instance of cortical blindness following subclavian vein puncture, emphasizing the need for awareness.
Area of Science:
- Neurology
- Vascular Surgery
Background:
- Central venous catheterization is a common procedure.
- Air embolism is a known complication.
- Neurologic deficits can occur.
Observation:
- A patient developed confusion and left hemiplegia after subclavian vein puncture.
- This was followed by transient cortical blindness.
- Pupillary reflexes were normal, and fundi showed no changes.
Findings:
- The described blindness was cortical in nature.
- This specific complication is rarely reported.
- Pathogenetic mechanisms require further investigation.
Implications:
- Highlights a rare but serious complication of central venous catheterization.
- Suggests the importance of vigilance for unusual neurologic symptoms.
- Informs clinical practice and patient safety protocols.
