“…Exercise habits have been reported to be associated with stent fracture. 20 It has been reported that stent fracture is associated with re-stenosis. 21 This may explain the higher stent fracture rate in the re-stenosis group observed here, because younger people are more likely to be active than older people.…”

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.

“…The 12-month results of the STELLA PTX registry, with TASC C and D femoropopliteal lesions (mean length 252 mm ± 90 mm) and paclitaxel eluting stents (mean number of stents 2.9), revealed a primary patency rate of 52.5 % with an incidence of 25 % in-stent re-stenosis and a stent fracture rate of 12,5 % on a limb basis and 9 % on a per stent basis [16]. It should also be mentioned that other data report the impact of stent fractures on long-time patency rates and clinical outcome remains less clear [17] or rather low [18].…”

Summary:Background: A new stent system was studied in a porcine model to evaluate its feasibility for spot-stenting of the femoropopliteal artery. Materials and methods: In a preliminary study in a single pig, handling and mechanical features of the novel multiple stent delivery system were tested. The Multi-LOC system demonstrated great feasibility regarding its pushability, trackability, and crossability. Excellent visibility of the individual stents allowed exact anatomically controlled implantation. In our main study, four to fi ve short Multi-LOC stents (13 mm long) were implanted into the femoropopliteal arteries of six domestic pigs and long (60 to 100 mm) self-expandable nitinol stents were implanted into the same target vessel contralaterally to allow for intraindividual comparison. After four weeks survival under dual antiplatelet treatment, control angiography was performed. The animals were euthanized, stented vessels were explanted, and histologic sections were examined for the presence of neointimal formation. Results: Multi-LOC stents demonstrated no occlusion of the femoropopliteal axis (0 vs. 1 occlusion distal to a control stent), no stent fractures (0 out of 26 vs. 2 out of 6 control stents), and lower percentage diameter stenosis (0.564 ± 0.056 vs. 0.712 ± 0.089; p = 0.008) and length of stenosis (19.715 ± 5.225 vs. 39.397 ± 11.182; p = 0.007) compared to a standard control stent, which was similar in total length to the multiple stented artery segment. Histological examination confi rmed myointimal hyperplasia underlying in-stent stenosis. Conclusions: The multiple stent delivery system was studied in a porcine model, which demonstrated its feasibility. Preclinical experience revealed favourable results concerning stent fracture, restenosis, and patency of spot-stented femoropopliteal arteries.

“…Patency at 12 months reduced from 84.3% to 41.1% in lesions with fractured stents [10]. Iida et al [11] reported the factors associated with stent fracture were longer lesion length, larger number of stents used, and exercise. In our case, the patient underwent implantation with three stents, with a total length of 300 mm, and the patient's exercise adherence was high.…”

Influence of Stent Fracture on the Long-Term Patency in the Femoro-Popliteal Artery

Abstract: Stent fracture worsened the patency during the first 2 years, but it did not apparently affect patency beyond 2 years. In particular, complete stent separation did not affect patency.
