Intrastent hematoma after treatment with a drug eluting balloon for in-stent restenosis: a case report
Abstract Back ground Intrastent hematoma after dilatation of in-stent restenosis is rarely reported and the optimal treatment for this condition remains unclear. Case summary We present the case of an 87-year-old man with in-stent subtotal occlusion of left circumflex (LCX). He experienced chest pain after drug eluting balloon (DEB) was released in the stent. Intravascular ultrasound (IVUS) revealed intrastent hematoma, which was not relieved with a cutting balloon but completely sealed by an Endeavor Resolute stent. Discussion Intrastent hematoma after dilatation of in-stent restenosis is rare. Reimplantation of stent seems the best method to solve this problem. IVUS imaging may provide insight into the cause of in-stent restenosis and guide the treatment.
