    Introduction: To evaluate the safety and efficacy of the pREset and pREset LITE1,2 (Phenox GmbH, Bochum, Germany) stent-retrievers in acute ischemic stroke (AIS) patients with a primary medium vessel occlusion (MeVO).

    Method(s): A retrospective review of the MAD-MT Consortium, a synthesis of prospectively maintained databases at 42 academic institutions in North America, Asia, and Europe, was performed to analyze consecutive AIS patients who underwent thrombectomy with the pREset 4x20 or pREset LITE 3x20 or 4x20 for a primary MeVO. Patients’ characteristics, procedural complications, angiographic and clinical outcomes were reviewed.

    Result(s): Between January 2017 and January 2022, 227 patients and MeVO were included (50% female, median age 78 [65–84] years, 45% of IVtPA before thrombectomy). The devices were used in 161/227 (71%,) “medium” vessels (M2, P1, A1) and in 66/227 (29%) “distal” vessels.

    Conclusion(s): Mechanical thrombectomy using the pREset and pREset LITE appears to be highly effective for MeVO among different centers and physicians, further studies are needed to better define the targeted population.
