The Follow-up Study Of Radial Artery Injury After Coronary Artery Intervention

OBJECTIVE: 120 patients which completed the coronary intervention by radial artery,were involved in order to evaluate the radial artery injury.METHODS: The patient's information including age,gender,smoking history,history of hypertension,history of dyslipidemia,history of coronary intervention,history of diabetes,the operation time etc,were collected through HIS system.The patient's vascular condition was initially assessed by the patient's symptoms,visual examination,palpation,and Allen's test.We used the doppler to record the information including the peak systolic velocity(PSV),the end diastolic velocity(EDV),the resistance index(RI)and the pulsation index(PI).If a patient right hand's PSV increased over 30% than the left,the patient developed hemodynamic changes.Continuous variables were expressed as mean ± standard deviation,and categorical variables were expressed as ratios.Comparisons between groups were made by U test and T test.P < 0.05 was statistically significant.RESULTS: All patients were completed the operation,and no hematoma and hemorrhage were observed.There were 17 cases of hemodynamic changes.In the patients with radial hemodynamic changes,the diameter of the right hand radial artery was generally lower than that of the left,while the indexes of PSV,EDV,PI and RI were increased.Hemodynamic changes may be associated with female(p<0.05),stent-implanted(p<0.05),and diabetes(p<0.05).Age,smoking history,history of hypertension,and dyslipidemia were not associated with changes in radial artery hemodynamics.For those patients with hemodynamic changes,only one patient was found pulse lost.And only one patient developed pain and discomfort.CONCLUSION: It was lower chance of complications in coronary intervention by radial artery.Female,stent-implanted,and diabetes may be the higher risk factors for radial artery injury.
