title: Longitudinal Stent Deformation Caused by Retraction of the Looped Main Branch Guidewire.
abstract: A 66-year-old male was treated percutaneously for a bifurcation lesion of the left anterior descending coronary artery by provisional stenting using the jailed wire technique. After successfully stenting the main branch, retraction of the looped main branch guidewire was impossible. After using an intravascular ultrasound we discovered the guidewire was entangled with a stent strut. Thereafter, the proximal stent elongated after retraction. With the support of an over-the-wire microcatheter, we finally pulled out the entrapped guidewire. This rare complication should remind physicians that it is important to prevent the distal guidewire from being looped while retracting it through a stent, regardless of whether it is in the side branch or main vessel. If the guidewire becomes entangled with a stent, a microcatheter or low-profile balloon can be advanced to rescue it before the stent is damaged. Furthermore, the microcather should be maintained after successful retraction of the entangled guidewire to facilitate further wiring and subsequent rescue angioplasty as necessary.
