摘　　要：目的　探讨冠状动脉搭桥术前胸廓内动脉和桡动脉用作桥血管的可能性。方法　应用二维彩色多普勒超声对 5 0例冠状动脉搭桥术前患者的 98条胸廓内动脉和 81条桡动脉血管内径、管壁、管腔及血流状况进行检测。结果　不适合作为桥血管的胸廓内动脉为 2 .0 4%,桡动脉为 8.6 4%。Objective To assess the value of color Doppler ultrasound for evaluation of suitability of internal thoracic artery (ITA) and radial artery (RA) as a coronary artery bypass graft preoperatively.Methods In 50 patients prior to having coronary artery bypass,gray scale and color Doppler ultrasound were used to evaluate the ITAs(n=98) and RAs (n=81).The wall and luminal diameter as well as characteristics of blood flow of the arteries was measured.Results Gray scale and color Doppler ultrasound demonstrated a variety of abnormalities in 2 ITAs and 7 RAs.One ITA showed reversed blood flow and another had narrowed lumen.Curving,intima media irregularity and thickening,narrowed lumen were observed in 5 RAs and plaques in two of them.The thrombosis was founded in 2 RAs.There are 2.04% of the ITA and 8.64% of the RA not suitable for bypass grafts.Conclusions Gray scale and color Doppler ultrasound can be used as a primary and effective tool to screen the suitability of the ITA and the RA as a coronary artery bypass graft preoperatively.
