Objective To analyze the risk factors for postoperative radial artery occlusion(RAO)in elderly patients with coronary heart disease(CHD)after transradial coronary intervention(TRI).Methods The elderly CHD patients(n=255)received TRI were chosen from Department of Cardiology in the 902nd Hospital of Chinese PLA Joint Logistics Support Force from Jan.2019 to Dec.2021.All patients were divided into RAO group and non-RAO group according to radial artery ultrasound results one month after the operation.The demographic and clinical data were compared between 2 groups,and risk factors of RAO were analyzed in elderly CHD patients one month after received TRI.Results There were 17 patients(6.67％)in RAO group,and 238 patients in non-RAO group(93.33％).The intraoperative dose of heparin was higher in RAO group than that in non-RAO group.The intima thickness of radial artery was higher in RAO group than that in non-RAO group.After the operation for 3 d,the higher radial artery diameter and peak value of radial blood flow velocity were independent protective factors for RAO one month after TRI.After the operation for 3 d,AUC of radial artery diameter was 0.711,and AUC of peak value of radial blood flow velocity was 0.976,which had higher diagnosis value to RAO one month after the operation.Conclusion The radial artery ultrasonography indexes 3 d after the operation can be used as predictors of RAO one month after the operation.It is suggested that complete RAO assessment should be improved before discharge for patients undergone radial artery puncture,and relevant intervention should also be actively given to patients with significant decrease of blood flow velocity.
