Abstract

This study aims at evaluating technical success and long-term results using Gore Excluder/C3 endoprosthesis in patients with narrow aortic bifurcation (NAB; inner aortic diameter < 18 mm). Clinical and anatomical data were collected retrospectively from patients treated in 2 high-volume Italian vascular centers between 2005 and 2017. A total of 1325 endovascular aneurysm repair procedures were performed, of which 195 involved Excluder/C3 Gore endoprosthesis. One hundred forty-one patients had a regular aortic bifurcation (RAB; maximum inner diameter ≥ 18 mm), whereas 54 presented with NAB (<18 mm). Technical success and procedural time were considered as primary outcomes. Secondary outcomes were perioperative complications, long-term graft-related complications and reintervention rates. Demographic data and risk factors were similar in the 2 groups. The mean diameter of aortic bifurcation was 29.8 ± 10.4 mm in RAB versus 17.1 ± 0.9 mm in NAB. Technical success was 100% in both groups. Incidence of intraoperative kinking/stenosis of limb graft was significantly higher in NAB (40.7% vs. 12.8%; P < 0.001), which was treated by means of kissing balloon technique (KiBaTe) and selective stenting. Time of procedure was similar. Post-o...Continue Reading
