Abstract

We describe a patient suffering from late stent thrombosis in a paclitaxel-eluting stent which had an underexpanded ring due to the three-hundred-sixty-degree circumferential calcified plaque. Intravascular ultrasound (IVUS) revealed rotational atherectomy could success-fully ablate both the metallic ring and the calcified ring. The ablated segment was scaffolded with a new paclitaxel-eluting stent, well ex-panded and documented by IVUS. To our knowledge, this is the first case report of stent ablation for an unexpanded paclitaxel-eluting stent. From the Medline index, there were only six case reports of stent ablation. We review and summarize the operation details of stent ablation from these reports.
