摘　　要：目的:比较数字减影血管造影(Digital subtraction angiography,DSA)引导下不同治疗方式对下肢动脉硬化闭塞症患者足背动脉血流动力学的影响。方法:回顾性收集2022年1月至2023年6月于本院完成治疗的92例下肢动脉硬化闭塞症患者的临床资料。根据DSA引导下不同治疗方式将患者分为球囊组(n=47,药物涂层球囊扩张术)和支架组(n=45,支架植入术)。比较两组的手术成功率,术前、术后3m足背动脉血流动力学[足背动脉内径、血流峰速、血流量]以及术后3 m不良事件发生情况。结果:两组的手术成功率无显著差异。术后3 m,两组的足背动脉血管内径、血流峰速及血流量均较术前显著升高(P<0.05);但两组间比较均无显著差异。球囊组术后不良事件发生率较支架组显著降低(P<0.05)。结论:DSA引导下支架植入术、药物涂层球囊扩张术治疗下肢动脉硬化闭塞症的效果相当,均能有效改善患者的足背动脉血流动力学。但与支架植入术比,药物涂层球囊扩张术可降低患者再狭窄和血运重建率,减少不良事件发生。Objective:To compare the effects of different treatments guided by digital subtraction angiography(DSA)on the hemodynamics of dorsalis pedis in patients with lower extremity arteriosclerosis obliterans.Methods:The clinical data of 92 patients with lower extremity arteriosclerosis obliterans who completed treatment in our hospital during 2022/01 to 2023/06 were retrospectively collected.Patients were divided into balloon group(n=47,drug-coated balloon dilation)and stent group(n=45,stent implantation)according to different treatment modalities guided by DSA.The success rate of operation,hemodynamics of dorsal foot artery[internal diameter of dorsal foot artery,peak velocity of blood flow and blood flow]before and 3 months after operation,and the occurrence of adverse events 3 months after operation were compared between two groups.Results:There was no significant difference in the success rate of operation between the two groups.At 3 months after operation,the internal diameter,peak blood flow velocity and blood flow of dorsal foot artery in two groups were significantly increased compared with those before operation(P<0.05).There was no significant difference between the two groups.The incidence of postoperative adverse events in balloon group was significantly lower than that in stent group(P<0.05).Conclusion:DSA-guided stenting and drug-coated balloon dilatation are equally effective in the treatment of lower extremity arteriosclerosis obliterans,both of which can effectively improve the hemodynamics of dorsalis pedis.However,compared with stent implantation,drug-coated balloon dilatation can reduce the restenosis and revascularization rate of patients and reduce the occurrence of adverse events.
