Acute ischemia of the hand developed after coronary artery bypass grafting with a radial artery conduit. Perioperative tests established that there was good perfusion to the hand via the collateral vessels. Angiographic examination showed an absence of the ulnar artery. Circulation was restored with a vein graft. I briefly review noninvasive investigations available and suggest that color Doppler scanning should be routinely performed before the use of the radial artery as a conduit.
采用桡动脉作为管道进行冠状动脉旁路移植术后出现手部急性缺血。围手术期检查证实通过侧支血管对手部有良好的灌注。血管造影检查显示尺动脉缺如。通过静脉移植恢复了循环。我简要回顾了现有的无创检查方法，并建议在将桡动脉用作管道之前应常规进行彩色多普勒扫描。
