AbstractTo explore the safety and efficacy of Sofia Plus distal access catheter tip shaping for treatment of acute middle cerebral artery embolism. This single-center retrospective study involved patients eligible for acute embolic middle cerebral artery occlusion from January 2020 to October 2021. They were divided into a shaping and non-shaping group according to whether the Sofia Plus catheter tip was shaped intraoperatively. Baseline data, preoperative Alberta Stroke Program Early Computed Tomography (ASPECT) score, National Institutes of Health Stroke Scale (NIHSS) score, onset-to-admission time, admission-to-puncture time, Sofia Plus-clot time, puncture-to-reperfusion time, surgical approach, and use of a stent for rescue thrombectomy were compared between the 2 groups. Postoperative symptomatic intracerebral hemorrhage and the modified Rankin scale score at the 90-day follow-up were observed. In total, 54 patients were enrolled in this study (shaping group, 26 patients; non-shaping group, 28 patients). Their mean age was 64.8 ± 14.6 years, and the proportion of men was 68.5% (37/54). Successful recanalization was achieved in all patients. There were no differences in the baseline data (age, sex, history, pre-admission ASPECT score, or NIHSS score) between the shaping and non-shaping groups. Patients treated with a shaped Sofia Plus catheter had a shorter Sofia Plus-clot time [median (25th, 75th percentile: 4 (4, 7) vs 10.5 (5.25, 14) min, P = .006] and puncture-to-reperfusion time [16.5 (12, 30.5) vs 26 (16.25, 38.25) min, P = .036]. There were significant differences in the surgical approaches between the 2 groups. The rates of a favorable outcome (57.7% vs 64.3%, P = .62) and postoperative symptomatic intracerebral hemorrhage (7.7% vs 3.6%, P = .60) were not significantly different between the groups. Sofia Plus catheter tip shaping improved catheter trafficability and reduced the operative time. It was safe and effective for treatment of acute middle cerebral artery thrombotic occlusion.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
