Drug-eluting stent implantation is an effective treatment for coronary artery disease, yet unexpected serious complications during stent implantation are possible. A 70-year-old man with unstable angina presented with a left main bifurcation lesion. Two drug-eluting stents were successfully deployed at the left main bifurcation lesion by the mini-crush technique under intravascular ultrasound guidance. However, after removal of the wire and intravascular ultrasound catheter, the stent of the proximal left circumflex artery was damaged and shortened at the distal edge. We used a looping wire technique to cross the injured stent and we successfully re-dilated the damaged portion of the stent. Finally, we deployed an additional drug-eluting stent at the left circumflex artery over the damaged stent. Our case illustrates the importance of gentle handling of devices during coronary intervention. Furthermore, interventionists should keep in mind the role of intravascular ultrasound when treating this kind of serious complication.
