Supraclavicular coronal oblique plane view and rainbow sign: A novel ultrasound technique for real-time detection and correction of guidewire misplacement during subclavian vein catheterization
Authors' conclusion
The supraclavicular coronal oblique plane view and "rainbow sign" provide a practical approach for real-time detection and correction of guidewire misplacement during subclavian vein catheterization.
Study context
- Population
- Patients undergoing elective gastrointestinal tumor surgery requiring US-guided right subclavian vein catheterization, tertiary hospital, March–August 2023
- Participants
- 93 patients
- Outcome
- Incidence of guidewire misplacement, success of redirection, and procedure-related complications
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Guidewire misplacement and redirection
Misplacement into ipsilateral internal jugular vein (10 patients)
10.8%
Misplacement into contralateral brachiocephalic vein (1 patient)
1.1%
Successful redirection of all 11 misplaced guidewires
100%
Observational data: associations, not effects.
Safety
Complications of redirection maneuver
- No complications, including no vascular injury, sustained arrhythmia or guidewire kinking
