Extensive late-acquired incomplete stent apposition after sirolimus-eluting stent implantation.

Choi HC, Hur SH, Nam CW, Cho YK, Kim H, Park NH, Kim YN, Kim KB - Korean Circ J (2010)

Bottom Line: 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.

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.

Intravascular ultrasound (IVUS) images of sirolimus-eluting stent in right coronary artery (RCA). 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 RCA (a-e) with stent fracture (c) at the follow-up. *incomplete stent apposition.

Mentions: To revascularize the LAD lesion, DESs were successfully implanted with a 3.5 by 23 mm Cypher and 3.0 by 23 mm Cypher with 20 atmospheres covering proximal to mid LAD with overlapping technique (MLD 2.93 mm). Intravascular ultrasound (IVUS, Atlantis Plus 40 MHz; Boston Scientific, Natick, MA, USA) was then performed with a pullback speed of 0.5 mm/sec from distal to middle RCA and from middle to proximal LAD. Nine months later, a scheduled follow-up CAG was performed (Figs. 2 and 3).
