wire escalation
Progressive use of increasingly supportive or specialized guidewires to cross challenging vascular lesions.
Full Definition
Wire escalation is a systematic interventional strategy involving the sequential use of guidewires with increasing support, stiffness, or specialized characteristics to successfully cross difficult vascular lesions. The technique typically begins with a standard workhorse wire and progresses through intermediate-support wires to high-support or specialty wires such as chronic total occlusion-specific designs. Wire escalation may also involve transitioning from hydrophilic to hydrophobic coatings, changing tip configurations, or employing different wire diameters. This graduated approach balances the need for lesion crossing capability while minimizing the risk of vessel perforation or dissection that can occur with overly aggressive initial wire selection.
Usage
Usage note: Implies a strategic approach rather than random wire selection; editors should ensure logical progression is described.
