Ann Vasc Surg 2024; 106:37-50. [PMID: 38604499 DOI: 10.1016/j.avsg.2024.02.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 02/18/2024] [Accepted: 02/20/2024] [Indexed: 04/13/2024]
Abstract
BACKGROUND The primary treatment for lower-extremity peripheral arterial occlusive disease (PAOD) is angioplasty stenting. Its main complication is in-stent restenosis. Poor selection of stent dimensions has been identified as a factor contributing to early in-stent restenosis. The aim of this study is to determine whether the implantation of stents, selected based on arterial morphological reconstruction using a sizing software program, reduces the occurrence of in-stent restenosis. The study also aims to evaluate the potential benefits of routine preoperative sizing. METHODS Between January 2016 and December 2020, all patients treated for PAOD through scheduled angioplasty stenting in our department were included in the study. Using systematic preoperative computed tomography angiography, precise reconstruction and sizing were performed to select the ideal length and diameter of stents, resulting in the selection of a so-called IDEAL stent. During the procedure, the surgeon implanted either the IDEAL stent or a different one, named the ACTUAL stent, based on intraoperative data and/or availability. We compared the in-stent restenosis rate between IDEAL and ACTUAL stents. RESULTS There were no significant differences in the overall characteristics between the IDEAL and ACTUAL stent groups. The in-stent restenosis rate at 1 year was 13% (N = 28/212, P = 0.994) in the IDEAL group and 17% (N = 25/149, P = 0.994) in the ACTUAL group. Among the ACTUAL stents, a total of 19.6% of stents with a diameter mismatch when chosen based on arteriography showed a significantly higher restenosis rate during the first year of follow-up (P = 0.02). CONCLUSIONS Our study did not demonstrate a significant difference in 1-year restenosis rate between the IDEAL and the ACTUAL stent groups. It specifically revealed the significant impact of diameter selection on the intrastent restenosis rate during the first year of follow-up. Stents chosen based on arteriographic criteria, which exhibited diameter discordance, compared to the IDEAL stents group selected using sizing reconstructions, could be either oversized or undersized. This led to a significantly higher restenosis rate at 1 year postoperatively.

Abstract
INTRODUCTION Endovascular therapy has emerged as a prominent strategy for managing femoropopliteal peripheral artery disease, offering acceptable safety and efficacy compared with open surgical bypass. Both paclitaxel-eluting stents and heparin-bonded covered stents have exhibited enhanced clinical outcomes compared with bare metal stents. However, there is currently a lack of level I evidence comparing the safety and efficacy of paclitaxel-eluting stents and heparin-bonded covered stents. Therefore, the primary objective of this study is to systematically evaluate the efficacy and safety outcomes of these two types of stents. METHODS AND ANALYSIS The ELITE trial is a prospective, multicentre, parallel, randomised controlled trial. A total of 450 patients will be recruited. The primary endpoints of the study include primary patency at 1 year post-index procedure. ETHICS AND DISSEMINATION Ethical approval for this study was obtained from the Ethics Committee of West China Hospital of Sichuan University (approval number: 2023-1186). The results will be submitted to a major clinical journal for peer review and publication. TRIAL REGISTRATION ELITE trial was registered on 27 September 2023 in the Chinese Clinical Trials Registry (ChiCTR2300076236).

Abstract
OBJECTIVES The study investigated mechanical parameters of stent systems indicated for treatment of femoropopliteal (FP) arterial disease to support interpretation of clinical results and the related causalities. METHODS Eight stent system types of same dimensions were investigated (n=2). Parameters were the profile of stent delivery system (SDS), radiopacity, trackability and pushability, bending stiffness (flexibility) and axial stiffness of expanded stents, length change during expansion, radial force, crush resistance, strut thickness and general surface condition. RESULTS The trackability ranged from 0.237 to 0.920 N and the pushability was 47.9-67.6 %. The bending stiffness of SDS was between 108.42 and 412.68 N mm2. The length change during stent release to 5 mm was low, with one exception. The bending stiffness of the expanded stents was 2.73-41.67 N mm2. The normalized radial forces at 5 mm diameter ranged from 0.133 N/mm to 0.503 N/mm. During non-radial compression by 50 %, the forces were 3.07-8.42 N, with one exception (58.7 N). The strut thickness was 153-231 µm. CONCLUSIONS Large differences occurred for flexibility, radial force and length change during expansion. The data should be used when choosing the proper device for restoring vascular function.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182211970. [PMID: 34831726 PMCID: PMC8617716 DOI: 10.3390/ijerph182211970] [Citation(s) in RCA: 55] [Impact Index Per Article: 18.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/23/2021] [Revised: 11/11/2021] [Accepted: 11/13/2021] [Indexed: 12/13/2022]
Abstract
Diabetes mellitus (DM) is a strong risk factor for the development of cardiovascular diseases such as coronary heart disease, cerebrovascular disease, and peripheral arterial disease (PAD). In the population of people living with DM, PAD is characterised by multi-level atherosclerotic lesions as well as greater involvement of the arteries below the knee. DM is also a factor that significantly increases the risk of lower limb amputation. Percutaneous balloon angioplasty with or without stent implantation is an important method of the treatment for atherosclerotic cardiovascular diseases, but restenosis is a factor limiting its long-term effectiveness. The pathogenesis of atherosclerosis in the course of DM differs slightly from that in the general population. In the population of people living with DM, more attention is drawn to such factors as inflammation, endothelial dysfunction, platelet dysfunction, blood rheological properties, hypercoagulability, and additional factors stimulating vascular smooth muscle cell proliferation. DM is a risk factor for restenosis. The purpose of this paper is to provide a review of the literature and to present the most important information on the current state of knowledge on mechanisms and the clinical significance of restenosis and in-stent restenosis in patients with DM, especially in association with the endovascular treatment of PAD. The role of such processes as inflammation, neointimal hyperplasia and neoatherosclerosis, allergy, resistance to antimitotic drugs used for coating stents and balloons, genetic factors, and technical and mechanical factors are discussed. The information on restenosis collected in this publication may be helpful in planning further research in this field, which may contribute to the formulation of more and more precise recommendations for the clinical practice.
