Key result
Wire passage through protruding stent struts, balloon crushing, and drug-eluting stent expansion successfully restored a large ostial lumen and vessel access in a case of instent restenosis.
Case Report (n=1)
Demonstrates a novel technique for treating aorto-ostial in-stent restenosis with stent protrusion when coaxial wiring is impossible.
May offer bailout option when coaxial access fails; single-case data leaves open reproducibility, safety, and durability.
We report a case of restenosis following ostial stenting of the right coronary artery, with protrusion of the stent into the aorta. Despite multiple attempts, no wire could be advanced coaxially inside the stent. The solution was to pass a wire through the struts of the protruding stent and crush it using progressively larger balloons and, finally, a drug-eluting stent was expanded to high pressure. The highlight of this case report is the final intravascular ultrasound image, revealing the profound deformation of the previous stent to restore a large ostial lumen and regain vessel access.

Kaplan et al. (2008) conducted a case report in Aorto-ostial instent restenosis (n=1). Wire passage through protruding stent struts, balloon crushing, and drug-eluting stent expansion was evaluated on Restoration of ostial lumen and vessel access. Wire passage through protruding stent struts, balloon crushing, and drug-eluting stent expansion successfully restored a large ostial lumen and vessel access in a case of instent restenosis.
