Conclusion
The guidewire knot was successfully removed under fluoroscopy using a push–pull technique in a hybrid operating room, avoiding a more invasive surgical procedure.
Supporting Evidence
- The guidewire penetrated the posterior wall of the vessel and formed a knot.
- Ultrasound and CT imaging were useful in diagnosing the guidewire migration and knot formation.
- The guidewire was safely removed without vascular injury.
Takeaway
Sometimes, when doctors put in a special tube to help patients, the wire can get stuck and make a knot. In this case, doctors used special pictures to help them safely take out the knot without hurting the patient.
Methodology
The guidewire was removed using fluoroscopic guidance in a hybrid operating room after it formed a knot during ultrasound-guided catheter insertion.
Participant Demographics
