INTRODUCTION: The aim of this study was to analyse early and follow-up results of the treatment of popliteal artery aneurysms (PAAs) performed with open surgical repair or with endovascular exclusion with endografts in a multicentric retrospective registry involving seven Italian vascular centres. MATERIALS AND METHODS: We retrospectively collected data concerning 178 open surgical interventions (OR group) and 134 endovascular exclusions (ER group) for PAAs performed between January 2000 and December 2011. Early and follow-up results were analysed in terms of mortality, graft patency, reintervention and limb preservation. RESULTS: OR patients were more frequently symptomatic (64%, 115 cases) than patients in the ER group (34%, 51 cases; p < 0.001), had more frequently acute limb ischaemia (23% and 6.5%, respectively; p < 0.001) and had more frequently a run-off score <2 (39% and 26%, respectively, p = 0.03). In the OR group there were no perioperative deaths; six thromboses (3.3%) and one amputation occurred. In the ER group mortality was 1.5%; 13 thromboses (9.7%) and one amputation (0.5%) occurred. Mean duration of follow-up was 30.6 ± 27.5 months. In the OR group primary and secondary patency, freedom from reintervention and limb preservation rates at 48 months were 63.5% (standard error (SE) 0.05), 76.5% (SE 0.05), 72.5% (SE 0.06) and 89.7% (SE 0.05), respectively. The corresponding figures in the ER group were 73.4% (SE 0.04), 85% (SE 0.04), 75% (SE 0.04) and 97% (SE 0.04), respectively. CONCLUSIONS: In this large multicentric retrospective registry, open and endovascular treatment of PAAs are used in different patients with regard to clinical and anatomical characteristics. Both treatments are feasible and safe, providing satisfactory early and long-term results.
