RESUMO
BACKGROUND: Endovascular treatment of iliofemoral occlusive disease is a challenging approach, especially for TransAtlantic Inter-Society C and D lesions. Therefore, the revascularization procedure in such situations is preferably performed by bypass graft surgery with synthetic materials. The purpose of this study is to report the feasibility and mid-term results of eversion endarterectomy of the external iliac artery (EEEIA), as an alternative autologous option. METHODS: Retrospective study with 18 EEEIA performed between September 2015 and February 2020, exclusively for chronic limb-threatening ischemia treatment in patients with increased risk of postoperative surgical infection and inadvisable for endovascular treatment. Demographic, clinical variables and outcomes were collected from a prospective database. The main end points are: amputation-free survival (AFS) and 30-day mortality. Secondary end points include: primary patency (PP), cumulative patency (CP), overall survival (OS), and postoperative surgical complication. KaplanMeier analysis was used to estimate cumulative time of outcomes. RESULTS: The mean age was 64.8 ± 8.3 years, with predominance of men. The median follow-up period was 1012 days, 95% confidence interval [119, 1365] days. Most had Rutherford 5 (n = 13, 72.2%) and mean ankle brachial index was 0.38 ± 0.22. The PP, CP, AFS, and OS in 730 days were 81%, 92%, 80%, and 88%, respectively. There was no 30-day mortality or postoperative surgical infection. CONCLUSIONS: Iliofemoral reconstruction through EEEIA is an effective surgical procedure with good patency rates, AFS and OS. In addition, it can be considered an useful and safe option, especially in cases in which a prosthesis should be avoided.
