Background: Percutaneous thrombectomy in patients with acute critical limb ischemia (CLI) is a challenging task. Several devices have been approved for this indication, but their effectiveness remains a matter of debate. The aim of this study is to present the first European experience with the Indigo aspiration thrombectomy system. Methods: A retrospective case review of all patients treated with the Indigo system between January 2016 and May 2017 in four European centers was conducted. The inclusion criterion was acute (≤14 days) lower limb ischemia. No exclusion criteria were used. Primary outcome was defined as technical success with restoration of antegrade blood flow without the need for thrombolysis or alternative revascularization strategies. Secondary outcomes included in-hospital serious adverse events (myocardial infarction, stroke, or death), need for blood transfusion, and in-hospital re-intervention. Results: Sixty-five cases of acute CLI were included in this study with 12-month follow-up. Technical success was achieved in all cases and for each treated vessel segment. No blood transfusions were required. No perforations, dissection, or neurovascular damage were encountered. Median-in-hospital stay was 2 days. One patient died during in-hospital stay due to heart failure and one patient suffered a myocardial infarction; both cases deemed to be unrelated to the procedure. On follow-up, 30-day reocclusion rate was 4% (from underlying primary causes such as AF). In these cases, repeat thrombectomy with the Indigo device was successfully performed. No episodes of reocclusion were reported on 12-month follow-up. Conclusion: In our experience, the Indigo system with its versatile range of catheters provides an easy, safe, robust, and trackable thrombectomy system in acute CLI cases with the capability to extract thrombus down to the pedal arch and without recourse to thrombolysis.
