Abstract:
Objective To discuss the short-term efficacy of endovascular recanalization for symptomatic non-acute internal carotid artery occlusion.Methods A total of 90 patients with symptomatic non-acute internal carotid artery occlusion,who were admitted to the Department of Neurology of Tianjin Municipal Teda Hospital of China from August 2017 to December 2021,were selected as the research objects.The patients were divided into study group(n=45)and control group(n=45).Percutaneous endovascular recanalization of internal carotid artery occlusion was performed for the patients of the study group,and standardized antiplatelet aggregation and anti-lipid therapy(including oral aspirin,clopidogrel bisulphate and atorvastatin)was adopted for the patients of the control group.The symptom recurrence rate at one year after treatment in both groups was analyzed.Results Of the 45 patients in the control group,4 were lost in touch,and 41 completed the one-year follow-up.Of the 45 patients in the study group,2 patients had failure of surgery,one patient had lost contact visit,and 42 completed the one-year follow-up.Postoperative intracranial hemorrhage occurred in 2 patients.After one year of follow-up,in the control group 26 patients(63.41％)developed recurrence of symptoms,presenting as transient ischemic attack(TIA,n=13,31.7％)and cerebral infarction(n=13,31.7％),and in the study group 8 patients(4.76％)developed recurrence of symptoms,presenting as TIA(n=6,14.3％)and cerebral infarction(n=2,4.8％);the incidence of cerebral infarction in the study group was strikingly lower than that in the control group,and the difference between the two groups was statistically significant(P＜0.05).In the patients with grade Ⅲ compensation,the recurrence rate of symptoms was remarkably decreased after endovascular recanalization of internal carotid artery occlusion,and the difference between the two groups was statistically significant(P＜0.05).However,in the patients with grade Ⅰ or grade Ⅱ compensation,although the recurrence rate of symptoms was decreased after endovascular recanalization of internal carotid artery occlusion,the difference between the two groups was not statistically significant(P＞0.05).Conclusion For the treatment of patients with symptomatic non-acute internal carotid artery occlusion,percutaneous endovascular recanalization of internal carotid artery occlusion is clinically safe,it can significantly decrease the recurrence rate of symptoms.
