冠状动脉搭桥术前常规超声检查相关血管的临床价值

Clinical value of ultrasonic examination of related blood vessels before coronary artery bypass graft

目的 评价冠状动脉搭桥术前常规超声检查进行桥血管筛查的价值。方法 总结 14 0例拟行冠状动脉搭桥术患者胸廓内动脉、颈动脉 (其中 74例患者同时检查双侧桡尺动脉 )的彩色多普勒超声检查结果并进行分析。结果 14 0例患者中 ,11例胸廓内动脉纤细或狭窄 ,2 8例存在不同程度颈内动脉狭窄。 74例患者桡尺动脉的超声检查中 ,14例左桡动脉存在低血流动力学状态 ,管径纤细 ,存在斑块、迂曲或尺动脉狭窄。结论 冠状动脉搭桥术前常规超声检查进行桥血管的筛查 ,对协助临床医师选择桥血管 ,减少手术风险 ,提高手术效果有着重要意义。

Objective To investigate the value of screening bridge vessels before coronary artery bypass graft(CABG) by ultrasonic examination. Methods To analyze the ultrasonic result of internal mammary arteries,carotid arteries,and radial arteries before CABG. Results Among the 140 cases,11 internal mammary arteries were not qualified,14 of 74 radial arteries were not qualified. And the stenosis of carotid arteries were present in 28 cases. Conclusions It is valuable to examine the bridge vessels before CABG.
