Background:
Intrastent haematoma after dilatation of in-stent restenosis (ISR) 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. He experienced chest pain after drug-eluting balloon was released in the stent. Intravascular ultrasound revealed intrastent haematoma, which was not relieved with a cutting balloon but completely sealed by an Endeavor Resolute stent.
Discussion:
Intrastent haematoma after dilatation of ISR is rare. Reimplantation of stent seems the best method to solve this problem. Intravascular ultrasound imaging may provide insight into the cause of ISR and guide the treatment.
