Angiographic and long-term clinical outcome of the sleeve technique in treating in-stent restenotic bifurcation lesions: A preliminary experience

Abstract

Background: No data has been published on the management of in-stent restenotic bifurcation lesions. The aim of this small case series was to examine the angiographic and long-term clinical outcomes of using sleeve technique to treat this lesion subset.

Methods: Six consecutive and symptomatic patients with MEDINA classification 1,1,1 in-stent restenotic bifurcation lesion were treated with drug-eluting stents using sleeve technique. Dual antiplatelet therapy was prescribed for an average of 13.5 ± 2.3 months.

Results: Most of the lesions (87%) were located at LAD/diagonal branch bifurcation. Kissing balloon inflation was performed successfully in all the patients. Follow-up angiography at nine months revealed a late loss of 0.35 ± 0.26 mm and 0.56 ± 0.56 mm in MV and SB, respectively. Angiographic restenosis was developed in 2 patients (33%), which were all located at the SB ostium. No in-hospital MACE was observed. One-year MACE was 17%, attributed by 1 patient with restenosis who needed revascularization. The mean follow up period was 50 ± 18 months, no stent thrombosis was detected.

Conclusions: The use of sleeve technique to treat in-stent restenotic bifurcation lesions is associated with good acute procedural result, a fairly low one-year MACE and long-term clinical safety.
