Abstract：Objective To compare the application effects of support catheter-assisted Solitaire FR stent mechanical thrombectomy(SWIM)and single stent thrombectomy on patients with acute anterior circulation large vessel occlusion.Methods The clinical data of 82 patients with acute anterior circulation large vessel occlusion in Pingdingshan Second People's Hospital between January 2020 and March 2023 were retrospectively analyzed.According to surgical methods,the patients were divided into single stent group(single stent thrombectomy,40 cases)and SWIM group(SWIM treatment,40 cases).Perioperative related indicators and postoperative vascular recanalization,neurological function and life function status before surgery and at 2 weeks after surgery,symptomatic hemorrhage conversion rate and craniocerebral hemorrhage rate at 3 months of follow-up after surgery were compared between the two groups.Results The surgery starting time,frequency of thrombectomy,hospital stay and total cost of hospitalization in SWIM group were less than those in single stent group(P＜0.05).There was no statistically significant difference in the vascular recanalization status between the two groups(grade 0,grade 1,grade 2a,grade 2b,grade 3)(P＞0.05).At 2 weeks after surgery,the National Institute of Health stroke scale(NIHSS)scores of the two groups were reduced(P＜0.05),and the score of SWIM group was significantly different from that of single stent group(P＜0.05).At 2 weeks after surgery,the activity of daily living(ADL)scores of the two groups were increased(P＜0.05),and the difference in the score was significant between SWIM group and single stent group(P＜0.05).During 3-month follow-up,there were no statistical differences in the symptomatic hemorrhage conversion rate and craniocerebral hemorrhage rate between the two groups(P＞0.05).Conclusion Both SWIM and single stent thrombectomy in the treatment of acute anterior circulation large vessel occlusion can obtain a good vascular recanalization rate,but compared with single stent thrombectomy,SWIM has better postoperative neurological function and quality of life in the treatment of patients with acute anterior circulation large vessel occlusion.
