Focal in-stent restenosis and in-stent thrombosis within the same bare-metal stent 5 years after deployment in a saphenous vein graft

J Invasive Cardiol. 2007 Dec;19(12):E369-71.

Abstract

Complications of percutaneous coronary intervention include in-stent restenosis (ISR) and in-stent thrombosis (IST) which have different underlying pathophysiological processes and different treatment strategies. ISR is primarily due to excessive neointimal growth and occurs in 20-30% of bare-metal stents (BMS). Drug-eluting stents (DES) have decreased the rates of ISR (< 10%), but are potentially associated with increased IST related to delayed arterial healing and stent strut exposure. ISR of BMS typically occurs within 6 months of stent deployment. IST usually occurs within 12 months of DES deployment. We present a case of focal ISR and IST within the same BMS, confirmed with intravascular ultrasound, 5 years after deployment in a saphenous vein graft.
