Endovascular treatment with iliac branch devices: multicenter study
Introduction: it is estimated that between 18 39 % of patients with aorto-iliac aneurysms undergoing endovascular treatment have a no suitable zone for distal sealing in common iliac arteries. Traditionally, one of the options is to perform distal seal at the external iliac arteries occluding the hy...

| Sumario: | Introduction: it is estimated that between 18 39 % of patients with aorto-iliac aneurysms undergoing endovascular treatment have a no suitable zone for distal sealing in common iliac arteries. Traditionally, one of the options is to perform distal seal at the external iliac arteries occluding the hypogastric arteries. However, this can lead to complications derived from pelvic ischemia in 28-55 % of cases. The use of iliac branched devices (IBD) allow to maintain the antegrade flow to the hypogastric arteries, avoiding these complications. the objective of our study is to analyze the medium-term results of endovascular exclusion of aorto-iliac aneurysms using IBD. Methods: a descriptive multicenter retrospetive study including the IBD for the endovascular treatment of aneurysms with involvement of the aor to iliac sector was conducted between January 2008 and July 2019. Demographic, anatomical, intra-perioperative and follow-up data was collected at 3 centers. The variables of interest analyzed were: technical success, perioperative mortality, incidence of pelvic ischemia, primary patency of the hypogastric branch and external iliac branch, DRI-related reoperation, and aneurysm-related mortality. Results: eighty IBDs were included from 61 patients: 28 (35 %) Gore (R) Excluder (R) Iliac Branch Endoprosthesis, and 52 (65 %) Cook (R) Zenith (R) Branch Endovascular Graft. Bilateral IBDs were implanted in 18 cases (29.5 %). The technical success was achieved in 95 % of cases, with no perioperative deaths. The mean follow-up was 30.1 (+/- 26.3) months. 6 patients presented pelvic ischemia during follow-up. The patency of the hypogastric side branch was 97.5 %, 94.5 %, and 90.6%, at 6, 12, and 24 months, respectively. the patency of the external iliac side branch was 100 %, 97.3 %, and 95.5 %, at 6, 12, 24 months, respectively. Freedom from reintervention rate secondary to IBD was 100 %, 96.8 %, and 94.7 %, at 6, 12, and 24 months, respectively. There was 1 case of aneurysm-related death during follow-up. Conclusions: in our experience, IBDs show good medium-term results in endovascular treatment of aorto-iliac aneurysms.These devices allow to maintain the perfusion of the hypogastric arteries, minimizing the incidence of pelvic ischemia. Although the appearance of late complications and the need for reinterventions is low, a long-term follow-up should be carried out to maintain the success of the procedure. |
