ABSTRACT
OBJECTIVES:
To analyze outcomes following endovascular treatment of total occlusion of the infrarenal aorta and aorto-iliac bifurcation in a multicenter Italian registry.METHODS:
It is a multicenter, retrospective, observational cohort study. From January 2015 to December 2018, 1306 endovascular interventions for aorto-iliac occlusive disease were recorded in the vascular registry. For this analysis, only patients treated for total occlusion of the infrarenal aorta and aorto-iliac bifurcation were included. Early (<30 days) primary outcomes of interest were technical success and mortality. Late major outcomes were primary and secondary patency and freedom from conversion to open aortic surgery.RESULTS:
A total of 54 (4.1%) patients met the inclusion criteria. Total percutaneous revascularization was possible in 41 (75.9%) patients and hybrid (endo plus open) intervention in 13 (24.1%) patients. The kissing-stent-graft technique was used in 45 (83.3%) cases, covered endovascular reconstruction of the aortic bifurcation (CERAB) in 5 (9.2%), and a unibody endograft deployed in 4 (7.4%). Technical success was 98.1% (n = 53). There were no episodes of intraoperative or perioperative vessel rupture. Conversion to open surgery was not necessary, and there were no in-hospital deaths. The median patient follow-up time was 16 months (interquartrile range [IQR], 6-27). The estimated primary patency rate was 95.8% ± 0.03 (95% confidence interval [CI] 85.5-98.9) at 1 year, 91.4% ± 0.05 (95% CI 76.2-97.2) at 2 years, and 85 ± 0.08 (95% CI 64.5-94.6) at 3 years. Cox regression analysis demonstrated that sex (hazard ratio [HR] 0.96; 95% CI 0.15-6.23, p = 0.963), extent of the occlusion (HR 0.28; 95% CI 0.05-1.46, p = 0.130), calcium score (HR 1.88; 95% CI 0.31-11.27, p = 0.490), or type of endovascular reconstruction (HR 0.80; 95% CI 0.13-5.15, p = 0.804) did not affect primary patency. Secondary patency was 95.5% ± 0.04 (95% CI 78.4-99.2) at 3 years. No patients required late conversion to open surgical bypass.CONCLUSIONS:
Endovascular reconstruction for total occlusion of the infrarenal aorta and aorto-iliac bifurcation was successful using a combination of percutaneous and hybrid revascularization techniques. Estimated patency rates at 3 years of follow-up are promising and are unaffected by the extent of occlusion or type of revascularization.Palabras clave
