Abstract：Objective To compare and analyze the effects of stent anchoring combined with Solumbra technique and stent thrombectomy alone on improving the prognosis,clinical efficacy and complications of patients with acute ischemic stroke.Methods The data of 169 patients with cerebral infarction who underwent interventional thrombectomy in Lianyungang First People's Hospital from December 2017 to October 2021 were retrospectively analyzed.According to the surgical methods of endovascular treatment,they were divided into stent-anchoring combined with Solumbra technique group(study group)and stent-only thrombectomy technique group(control group).The vascular recanalization rate,operation time,complications and good prognosis rate of the two groups were compared,and the effectiveness and safety of stent anchoring combined with Solumbra technology were analyzed.Results There were no significant differences in age,gender,anesthesia mode,past medical history,intravenous thrombolysis,OPT time and admission NIHSS score between the two groups(P>0.05).The recanalization rate of the first thrombectomy in the study group was 48.6%,which was significantly higher than 28.1%in the control group(χ2=6.881,P<0.05).The time from puncture to reperfusion was(108.6±58.2)min,which was significantly shorter than(128.5±56.7)min in the control group(t=-2.048,P>0.05).The secondary embolization rate in the study group was 18.1%,which was significantly lower than 35.9%in the control group(χ2=6.778,P<0.05).There were no significant differences in the final recanalization rate,symptomatic intracranial hemorrhage rate and good prognosis rate between the two groups(all P>0.05).In patients with internal carotid occlusion,the first thrombectomy recanalization rate of the study group was 45.2%,which was significantly higher than that of the control group(14.3%)(χ2=5.424,P<0.05).There were no significant differences in the final recanalization rate of the internal carotid artery and in the first-pass and final recanalization rates of the middle cerebral artery and posterior circulation(all P>0.05).Conclusion This study shows that compared with stent thrombectomy alone,stent anchoring combined with Solumbra technology in patients with acute ischemic stroke in endovascular interventional therapy is safe and effective,can increase the first-pass recanalization rate,shorten the operation time,reduce secondary thrombosis risk due to thrombus escape,thus improving the prognosis of patients.
