Summary
A new technique allows sheath upsizing during peripheral arterial interventions without losing guidewire access to target lesions. This method ensures continued treatment despite unexpected complications, maintaining critical guidewire positioning.
Area of Science:
- Interventional Cardiology
- Vascular Surgery
- Medical Device Technology
Background:
- The 4-F platform is common in peripheral arterial interventions, supporting 0.018″ and 0.014″ guidewires.
- Unexpected complications may necessitate urgent sheath upsizing during these procedures.
Purpose of the Study:
- To describe a novel technique for safe sheath upsizing during peripheral arterial interventions.
- To maintain guidewire access to target lesions after sheath upsizing.
Main Methods:
- A technique for bailout sheath upsizing is presented.
- The method focuses on preserving the position of low-profile guidewires across target lesions.
Main Results:
- The described technique facilitates safe sheath upsizing.
- Access to target lesions is maintained throughout the procedure.
Conclusions:
- This technique offers a reliable solution for sheath upsizing in peripheral arterial interventions.
- It is applicable across various clinical scenarios requiring urgent procedural adjustments.
