“…Smoking, diabetes mellitus, and hyperlipidemia are demonstrated predictors for PAD and in-stent re-stenosis [15]. Although taking precautions against these factors may decrease in-stent re-stenosis in the short term, stent obstructions cannot be prevented in the long term [16].…”

Aim: Thrombocytes play a key role in atherosclerosis and acute vascular events. The purpose of this study is to investigate the association between mean platelet volume (MPV), platelet counts as well as other hematological parameters and biodegradable stent restenosis. Methods: 53 patients who underwent percutaneous biodegradable peripheral stent placement procedure were included in this retrospective cohort study. Blood samples were collected a day before the operation. Patients were followed for a mean of 6 months and Doppler ultrasonography (DUSG) was performed for control examination. According to the DUSG results, patients were divided into two groups: Group 1 included patients with ≥50% in-stent re-stenosis and Group 2, with <50% in-stent re-stenosis. Results: The mean age of the patients was 58.1 (6.7) years. 6 (11.3%) patients were female and 47 (88.7%) patients were male. Eight (15%) had iliac artery and 45 (84.9%) had superficial femoral artery stenosis. Doppler US reports showed that 11 (20.8%) patients had ≥50% in-stent re-stenosis (Group 1). Re-stenosis rates were higher at younger ages (P=0.020). There was no statistically difference between the groups in terms of gender (P=0.636), MPV (P=0.210), PLT counts (P=0.129) or any other hematologic parameters. Conclusion: Several studies have shown that some blood parameters, especially MPV, are effective on coronary and peripheral stent stenosis. In our study, we found that none of the hematologic or common blood parameters can predict biodegradable stents re-stenosis.

“…1 The interwoven Supera nitinol stent has significantly higher radial resistive force and crush resistance than lasercut stents, which may be ideal qualities for calcified lesions. [17][18][19] However, the design of the Supera stent requires sufficient space in the lumen to facilitate complete stent expansion and avoid elongation, a factor known to reduce patency. 19 Aggressive predilation and balloon oversizing may be necessary to create that space; however, such aggression in calcified arteries brings with it a significant risk of perforation.…”

“…Therefore, it is very important to know the clinical features that may cause in-stent restenosis. It has been demonstrated that many parameters including diabetes mellitus, smoking, dyslipidemia, long complex lesions, and age are predictors of the in-stent restenosis after SFA interventions in the follow-up [ 16 , 17 ]. The rates of in-stent restenosis can be decreased by taking several precautions to these clinical features.…”

Background The mean platelet volume (MPV), the most commonly used measure of the platelet size, is a cheap and easy-to-use marker of the platelet activation. We aimed to evaluate the relationship between preprocedural MPV and other hematologic blood count parameters and in-stent restenosis in patients with superficial femoral artery (SFA) stenting. Methods and Results The consecutive 118 patients who successfully underwent endovascular stenting of the SFA were enrolled retrospectively in the study. The mean follow-up was 23 ± 12 months. The in-stent restenosis was observed in 42 patients (35.6%). There were no statistically significant differences between the restenosis group and no-restenosis group in terms of age, gender, and smoking (p=0.116, p=0.924, and p=0.428, resp.). In the restenosis group, the MPV level was markedly higher than that in the no-restenosis group, and it was statistically significant (p < 0.001). According to the ROC curve analysis, the optimal cutoff value of the MPV to determine the restenosis was >8.7 fL, and the level of the MPV >8.7 fL was a strong predictor of the restenosis (p < 0.001) in logistic regression analysis. Conclusions The measurement of the preprocedural MPV levels may help to identify high-risk patients for development of the in-stent restenosis. These patients may benefit from an aggresive antiplatelet therapy and close follow-up.

Predictors of restenosis in the use of helical interwoven nitinol stents to treat femoropopliteal occlusive disease

Abstract: Our midterm experience showed that the implantation of the helical interwoven nitinol stents in patients with femoropopliteal occlusive disease is safe and effective, with encouraging patency rates and clinical results.
