Long-Term Results of the S.M.A.R.T. ControlTM Stent for Superficial Femoral Artery Lesions, J-SMART Registry

Abstract

Background:The use of a stent in the treatment of lesions of the superficial femoral artery (SFA) remains controversial. Although some reports have suggested that use of a nitinol stent in conjunction with aggressive medical management is effective for long SFA lesions, few long-term, large-scale studies have been done. Methods and Results:A retrospective analysis was conducted of data from a multicenter study in which the S.M.A.R.T. Control™ stent was used for treatment of de novo SFA lesions. A total of 528 lesions in 432 patients were included. Mean patient age was 72.5±9.1 years; mean stent length was 15.7±8.1 cm; 259 lesions (49%) were classified as C/D according to the TransAtlantic Inter-Society Consensus (TASC) II classification. Primary and secondary patency at 4 years was 66% and 87%, respectively. No cilostazol administration (41% re-stenosis group vs. 29% no-restenosis group, P<0.01), female gender (42% vs. 26%, P<0.01), younger age (70.7±9.3 years vs. 72.9±9.0 years, P<0.05), and chronic total occlusion (CTO; 72% vs. 52%, P<0.01) were independent predictors of re-stenosis.Conclusions: The S.M.A.R.T. Control™ stent provided good long-term durability in the treatment of SFA lesions, and no cilostazol administration, female gender, younger age and CTO were associated with re-stenosis.

Impact of Post-Procedural Intravascular Ultrasound Findings on Long-Term Results Following Self-Expanding Nitinol Stenting in Superficial Femoral Artery Lesions

“…6 Female gender, younger age, diabetes mellitus, no cilostazol, CLI, CTO, TASC II C/D lesion, and stent fracture have been associated with restenosis following nitinol stenting in the SFA. [16][17][18] In this study, female gender and TASC II C/D lesion were more prevalent in the TLR group compared to the no-TLR group on univariate analysis, but age, diabetes mellitus, use of cilostazol, CLI, and CTO were similar between the 2 groups. Previous studies reported that use of cilostazol pre-(25%) were detected on angiogram.…”

Long-term follow-up after endovascular revascularisation for acute limb ischaemia - a retrospective single-centre cohort

“…In several studies, female gender was identifi ed as an independent risk factor for restenosis in the superfi cial femoral artery (SFA) after stent implantation [10,11]. This may correlate to the fi nding that female patients have a worse outcome regarding amputation and survival in the study of Kashyap et al [12].…”
