Outcome Measures

Primary Outcomes (1)

  • Technical success using the Indigo system.

    Intraoperative technical success defined as the restoration of antegrade blood flow with complete or near complete (95% by volume) removal of the thrombus or embolus (70% threshold). This is assessed using imaging modalities (USS/Doppler/Fluroscopy) and clinical assessment of the affected limb. See for this definition the enclosed citation. In conclusion, the primary outcome measure will be improvement in blood flow across a lesion assessed by the improvement in Thrombolysis in Myocardial Infarction (TIMI) score that was adapted to peripheral arteries. Concomitant balloon angioplasty or stent placement in addition to VAT was considered a complementary treatment. Additional thrombectomy treatments, such as thrombolysis and mechanical thrombectomy, were considered technical failures.Target lesions were grouped anatomically into above-the-knee(ATK) or below-the-knee(BTK) lesions.

    Time to event anaylsis. Primary patency results are immediate after the case on the final angiogram images.
