Abstract:
Objective To investigate the effect of 3D rotational digital subtraction angiography(DSA)-guided drug balloon predilation bare-metal stents on vertebral artery origin stenosis(VAOS).Methods A total of 63 VAOS patients who were admitted to Hai'an People's Hospital from May 2020 to December 2022 were selected and divided into two groups according to different treatment methods.There were 16 males and 14 females with a mean age of(52.10±3.62)years in the observation group.There were 19 males and 14 females with a mean age of(52.47±3.85)years in the control group.There was no statistical difference in the basic data between the two groups(P>0.05).The observation group was treated with 3D rotational DSA-guided drug balloon predilation bare-metal stent,while the control group was treated with conventional drug balloon predilation bare-metal stent.The efficacy of the two groups was compared.Results The success rate of operation was 100%(30/30)in the observation group,which was higher than that in the control group(96.97%[32/33],χ2=0.924,P=0.336).There was no significant difference in the stenosis rate between the two groups either before surgery or 3 months after surgery(P>0.05).The hemodynamic level of the initial segment of vertebral artery in the observation group was lower than that in the control group 3 months after surgery(P<0.05).The scores of neurological function and quality of life at 3 months after surgery and the incidence of recurrent stroke at 6 months after surgery in the observation group were lower than those in the control group(P<0.05).Restenosis occurred in 2 cases(6.67%)in the observation group and 9 cases(27.27%)in the control group,and there was significant difference in the incidence of restenosis between the two groups(χ2=4.630,P=0.031).Conclusion 3D rotational DSA-guided drug balloon predilation bare-metal stent can effectively reduce the stenosis rate and the incidence of restenosis,and improve the nerve function and the quality of life of VAOS patients.
