Aterectomia rotacional para o tratamento da reestenose intrastent

Abstract

We report a case of a patient with bare metal stent restenosis secondary to stent underexpansion, due to a heavily calcified atherosclerotic plaque, which was not identified by angiography. Intravascular ultrasound was important to recognize the mechanism of restenosis and determine the best strategy to be used. Rotational atherectomy was successfully used to weaken peristent calcium, allowing the posterior expansion of the prosthesis using high pressure balloon dilatation.
