Objectives The objective of this study was to determine the prevalence of fractures in stents implanted in the SFA and to identify predisposing factors for these fractures together with their impact on the patency of these devices.  Methods The study included 39 patients (65.7\u00b19.0 years) who previously underwent angioplasty for delivery of 56 stents into the SFA. During follow-up, which ranged from 7 to 46 months, variables were collected on the characteristics of the lesions treated and characteristics of the stents implanted. Two examiners independently analyzed digital radiographs for the presence of stent fractures and the patency of the devices.  Results We found a 10.7% prevalence of fracture of implanted stents. Implantation of multiple stents was identified as a significant predisposing factor for fractures. We observed a marked tendency for fractures in female patients and in lesions treated with longer stents (&gt; 150 mm). Stenosis exceeding 50% and occlusions were significantly more frequent in fractured stents.  Conclusions This study suggests that implants longer than 150 mm and multiple stents are associated with higher device fracture rates. In cases with stent fractures, stenoses exceeding 50% and occlusions were significantly more frequent.<\/jats:p>","DOI":"10.1590\/1677-5449.202000142","type":"journal-article","created":{"date-parts":[[2022,9,19]],"date-time":"2022-09-19T13:19:53Z","timestamp":1663593593000},"source":"Crossref","is-referenced-by-count":8,"title":["Stent fractures in the superficial femoral artery: predisposing factors and their implications"],"prefix":"10.1590","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0240-8854","authenticated-orcid":false,"given":"Fernando Tr\u00e9s","family":"Silveira","sequence":"first","affiliation":[{"name":"Faculdade de Ci\u00eancias M\u00e9dicas da Santa Casa de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2587-3639","authenticated-orcid":false,"given":"\u00c1lvaro","family":"Razuk Filho","sequence":"additional","affiliation":[{"name":"Faculdade de Ci\u00eancias M\u00e9dicas da Santa Casa de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5377-0074","authenticated-orcid":false,"given":"Paulo Fernandes","family":"Saad","sequence":"additional","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brasil;
