Objective:To investigate the feasibility of transradial artery approach for coronary angiography and for bilateral carotid angiograohy at the same time.Methods:There vdere 39 patients(remale 18 and male 21)with a mean age of 65 years(range 49-72).Transradial artery approach for coronary angiography was performed,at the same time,selective bilateral carotid angiography was performed with Simmons catheter.Results:Thirty-seven patients completed the selective coronary angiography and bilateral carotid angiography successfully,and 2 failed.The success rate was 94.5%,and no complications occurred.Comlmiom:Transradial artery approach for selective bilateral carotid angiograohy is safe and feasible.
