wire escalation
The systematic progression from softer to increasingly stiff guidewires during endovascular procedures to achieve lesion crossing.
Full Definition
Wire escalation is a fundamental endovascular technique involving the sequential use of guidewires with increasing stiffness and tip load to successfully cross challenging arterial lesions. The approach typically begins with soft, hydrophilic wires and progresses through intermediate to stiff wires based on lesion characteristics and crossing difficulty. This systematic approach minimizes vessel trauma while maximizing crossing success rates. Wire selection depends on factors including lesion morphology, calcification, chronicity, and vessel tortuosity. Proper wire escalation requires understanding of different wire properties, including tip load, shaft support, and coating characteristics to optimize procedural success and safety.
Usage
Usage note: Hyphenate when used as compound adjective (wire-escalation technique).
