wire crossing
Successful advancement of a guidewire through a stenotic or occluded vessel segment during endovascular procedures.
Full Definition
Wire crossing represents a critical technical milestone in endovascular interventions, involving the successful passage of a guidewire through stenotic, calcified, or totally occluded vessel segments. This fundamental step enables subsequent catheter and device delivery for therapeutic intervention. Successful wire crossing depends on proper wire selection, fluoroscopic guidance, tactile feedback, and operator technique. Challenging crossings may require specialized wires, support catheters, or alternative access approaches. Failed wire crossing attempts can lead to complications including vessel perforation, dissection, or subintimal passage. Documentation should specify wire type, crossing technique, and any complications encountered during attempts.
Usage
Usage note: Document wire type, number of attempts, and confirmation of intraluminal position during crossing procedures.
In Context
- "Wire crossing was achieved on the second attempt using a hydrophilic guidewire." — Procedure report
- "Successful wire crossing confirmed the intraluminal position before balloon advancement." — Technical documentation
