Abstract

Abstract : Introduction: Mechanical thrombectomy has been established as the mainstay of treatment for large vessel occlusion stroke. Direct aspiration as a first-pass technique in mechanical thrombectomy is attractive due to the cost-effectiveness and timeliness, and has been shown to be non-inferior to stent-retrieval in a randomized study. We present our experience with the Large-Bore Catheter (Cerenovus, Inc.) as the first-pass device in mechanical thrombectomy. Methods: We retrospectively analyzed all patients treated with mechanical thrombectomy between January, 2021, and January, 2022. Patients were included if the Large Bore catheter was used for direct aspiration on the first thrombectomy attempt. Patient demographics, procedure specifics, imaging, and outcome data were collected. Results: A total of 50 cases met inclusion criteria, and were included, of which 32 (64%) were male. The average age was 68.8 years. The median ASPECTS score was 9. Median puncture-to-reperfusion time was 14 minutes. First-pass recanalization was achieved in 24 cases (48%). A stentriever was employed for subsequent passes in 20 cases (40%). Successful recanalization (TICI 2b-3) was achieved in 48 cases (96%). Ninety-day outcome data was available for 36 patients. Of these, mRS 0–2 was achieved in 18 (50%) of patients, while 8 patients (22.2%) were dead (mRS 6) at 90 days. Conclusions: Our single-center experience with the Large Bore Catheter shows successful recanalization and low reperfusion times, with first-pass recanalization in a significant proportion of cases.
