Abstract:
Objective To investigate the clinical effect of endovascular stent implantation and medical treatment in the treatment of symptomatic vertebral artery stenosis. Methods Eighty patients with symptomatic vertebral artery stenosis admitted from January 2013 to May 2015 in the Department of Neurology of Wuhan Puren Hospital were selected. The patients were randomly divided into the observation group and the control group,with 40 cases in each group. The control group was given aspirin enteric?coated tablets 100 mg/ time,1 time /d,clopidogrel bisulfate bablets 75 mg/ time,1 time /d,atorvastatin calcium 10 mg/ time,1 time/d. The observation group was treated with intravascular stent implantation. After 1 years of follow?up, the degree of vascular stenosis,the occurrence of ischemic cerebrovascular time and the clinical effect of the two groups were compared. Results (1) The stenosis degree of the observation group and the control group before treatment was (72. 81±11. 99)％ and (68. 31±12. 35)％ respectively,after treatment,it was (24. 58±1. 24)％ and (56. 01 ±3. 30)％ respectively. There was no significant difference between the two groups before treatment (t=0. 121,P>0. 05). After treatment,vascular stenosis degree in two groups were significantly improved,compared with that before treatment,the differences were statistically significant (t=0. 790,P<0. 05; t=0. 457,P<0. 05); the degree of vascular stenosis after treatment in the observation group was significantly lower than that in the control group ( t=0. 842,P<0. 05);( 2) during follow?up,the total occurrence rate of ischemic cerebrovascular events in the observation group was 17. 5％ (7/40),compared to 37. 5％ (15/40) in the control group,the difference between the two groups was statistically significant (χ2=4. 065,P<0. 05) . ( 3) At 1 years of follow?up,the total effective rate of the observation group was 97. 5％ ( 39/40) ,while that of the control group was 60％ ( 24/40) , and the difference between the two groups was statistically significant ( P=0. 017) . Conclusion Endovascular stent implantation can effectively improve the clinical efficacy of symptomatic vertebral artery, reduce the incidence of ischemic cerebrovascular time,and improve the degree of vascular stenosis.
