The feasibility of using modified Allen tests to evaluate arterial circulation in the forearm for possible radial artery grafting, and the correlation of these tests with Doppler ultrasonography, were examined. The hand circulation of 50 patients scheduled for coronary artery bypass grafting was assessed by plethysmography, pulse oximetry, and pencil Doppler, as well as Doppler ultrasonography. Flow, velocity, and diameter of the radial, ulnar, and snuffbox arteries were recorded, and radiological screening indices were evaluated to establish a standard set of criteria. The results of modified Allen tests by plethysmography and pulse oximetry demonstrated the dominance of the ulnar artery. The indices of flow x diameter and velocity x diameter, obtained from Doppler ultrasound measurements, confirmed the dominance of the ulnar artery. When compression was applied to the arteries sequentially, significant alterations were found. The arterial circulation in the forearm can be safely evaluated by the modified Allen tests with plethysmography, pulse oximetry, and pencil Doppler, as these results correlated with Doppler ultrasound.
研究了使用改良艾伦试验评估前臂动脉循环以确定是否适合桡动脉移植的可行性，以及这些试验与多普勒超声检查的相关性。对50例计划进行冠状动脉旁路移植术的患者，通过体积描记法、脉搏血氧饱和度测定法、笔式多普勒以及多普勒超声检查来评估手部循环。记录桡动脉、尺动脉和鼻烟窝动脉的血流、速度和直径，并评估放射学筛查指标以建立一套标准标准。通过体积描记法和脉搏血氧饱和度测定法进行的改良艾伦试验结果显示尺动脉占优势。从多普勒超声测量获得的血流×直径和速度×直径指标证实了尺动脉的优势。当依次对动脉施加压迫时，发现了显著变化。改良艾伦试验结合体积描记法、脉搏血氧饱和度测定法和笔式多普勒能够安全地评估前臂的动脉循环，因为这些结果与多普勒超声检查相关。
