Résumé
To describe the outcomes of the endovascular reconstruction of TASC C/D lesions involving the infrarenal aorta and aortic bifurcation with different techniques. This is an observational, retrospective, single-center study. In a 5-year period, we selected all the patients treated with an endovascular procedure for an aorto-iliac TASC C/D lesion involving the infrarenal aorta and/or the aortic bifurcation. Early (<30 days) outcomes were mortality, major amputation, and thrombosis. Late mid-term (1 and 3 years) outcomes were primary, assisted primary and secondary patency, limb salvage rate, and freedom from reintervention. A total of 87 patients were treated during the index period. Kissing covered stent (cKS), covered reconstruction of aortic bifurcation (CERAB), and unimodular bifurcated AFX Unibody stent-graft (Bif-SG) implantation were performed in 35 (40.4%), 26 (29.8%), and 26 (29.8%) cases, respectively. Bif-SG group included 11 (11/26, 42.3%) patients treated for abdominal aortic aneurysm associated with the obstruction of the aortic bifurcation. Technical success was achieved in all cases and no ruptures or conversions to open surgery were recoded. Median follow-up age was 18 months (interquartile range [IQR], 8-34). Overall primary patency rate was 91.2% (95% confidence interval [CI]: 81.3-95.9) at 1 year and 83.5% (95% CI: 69.6-91.4) at 3 years. Assisted primary patency was 96.9% (95% CI: 87.8-99.2) at 1 and 3 years. Secondary patency was 97.8% (95% CI: 85.5-99.6) at 3 years. Limb salvage rate was 98.6% (95% CI: 90.1-99.7) at 1 and 3 years and, freedom from reintervention was 98.4% (95% CI: 88.9-99.7) at 1 year and 87% (95% CI: 66.1-95.4) at 3 years. Univariate analysis did not identify any factor affecting primary patency rate. Endovascular reconstruction in severe aorto-iliac obstructions using advanced techniques offered promising mid-term patency rates and profiles of safety. The variety of reconstructive configurations allows surgeons to customize on patients' anatomies the type of revascularization.

This is an observational, retrospective, single-center study. In a 5-year period, we selected all the patients treated with an endovascular procedure for an aorto-iliac TASC C/D lesion involving the infrarenal aorta and/or the aortic bifurcation. Early (<30 days) outcomes were mortality, major amputation, and thrombosis.

RESULTS
A total of 87 patients were treated during the index period. Kissing covered stent (cKS), covered reconstruction of aortic bifurcation (CERAB), and unimodular bifurcated AFX Unibody stent-graft (Bif-SG) implantation were performed in 35 (40.4%), 26 (29.8%), and 26 (29.8%) cases, respectively. Bif-SG group included 11 (11/26, 42.3%) patients treated for abdominal aortic aneurysm associated with the obstruction of the aortic bifurcation. Technical success was achieved in all cases and no ruptures or conversions to open surgery were recoded. Median follow-up age was 18 months (interquartile range [IQR], 8-34). Overall primary patency rate was 91.2% (95% confidence interval [CI]: 81.3-95.9) at 1 year and 83.5% (95% CI: 69.6-91.4) at 3 years. Assisted primary patency was 96.9% (95% CI: 87.8-99.2) at 1 and 3 years. Secondary patency was 97.8% (95% CI: 85.5-99.6) at 3 years.
