To investigate the chronic consequences of radial artery removal for coronary artery bypass surgery on the forearm circulation.
Thirty-nine patients submitted to radial artery removal for coronary artery bypass were submitted to serial Echo-Doppler evaluation of the flow and morphology of the forearm arteries until 10 years follow-up.
The peak systolic velocity of the ulnar artery of the operated side was significantly higher than the control site. The intima-media thickness of the ulnar artery was always significantly higher on the operated side, and this difference reached statistical significance at 10 years follow-up. There was a significantly higher prevalence of atherosclerotic plaques in the ulnar artery (UA) of the operated versus control arm (11/39 vs 0/39; p=0.005).
Radial artery removal for coronary artery bypass surgery leads to a chronic increase in ulnar flow accompanied by increased intima-media thickness and accelerated atherosclerotic disease. These findings may have potentially important implications for surgical indications and patients management.
探讨冠状动脉搭桥手术中桡动脉移除对前臂循环的长期影响。
39例行冠状动脉搭桥手术并移除桡动脉的患者接受了系列超声多普勒评估，以观察前臂动脉的血流和形态，随访长达10年。
手术侧尺动脉的收缩期峰值流速显著高于对照部位。手术侧尺动脉的内膜中层厚度始终显著更高，且在10年随访时这种差异具有统计学意义。手术侧与对照侧尺动脉中动脉粥样硬化斑块的患病率显著更高（11/39比0/39；p=0.005）。
冠状动脉搭桥手术中移除桡动脉会导致尺动脉血流长期增加，同时伴有内膜中层厚度增加和动脉粥样硬化疾病加速。这些发现可能对外科手术指征和患者管理具有潜在的重要意义。
