Abstract

Late-acquired incomplete stent apposition (ISA) is frequently observed after drug-eluting stent (DES) implantation. Most incidences of late-acquired ISA induced by positive vascular remodeling were of the focal type and occurred in a single vessel. We present an unusual case of a 45-year-old male subject diagnosed with late-acquired ISA that occurred in multiple vessels.

  Fig. 2 Intravascular ultrasound (IVUS) images of sirolimus-eluting stents in left anterior descending artery (LAD). A: post-stenting IVUS. The stent struts were well apposed to the vessel wall at the time of implantation. B: nine month follow-up IVUS. Incomplete stent apposition was found diffusely from proximal to distal LAD (a-e) at the follow-up. *incomplete stent apposition.

The stent struts were well apposed to the vessel wall at the time of implantation. B: nine month follow-up IVUS. Incomplete stent apposition was found diffusely from proximal to distal RCA (a-e) with stent fracture (c) at the follow-up. *incomplete stent apposition.
