There is a lack of data regarding the baseline hemodynamic blood flow parameters of the wrist and digits. Therefore, we aimed to quantify the digital and radial artery blood flow parameters using ultrasound and assess the influence of patient characteristics on hemodynamics.
We analyzed ultrasonographic data from 25 patients (50 hands) between October 2019 and December 2021. Variables of interest included dimensions of the radial artery and index finger (IF) ulnar and radial digital arteries at the palmodigital crease and their corresponding flow parameters. We compared variables among men and women and patients with and without diabetes using Wilcoxon Rank Sum test.
Our cohort consisted of 18 women (36 hands) and three participants with diabetes (six hands). The mean diameter of the IF radial digital artery was 7 mm, and that of the ulnar digital artery was 10 mm. The average peak systolic velocity for the radial digital artery was 21.31 cm/sec, and for the ulnar digital artery, it was 30.03 cm/sec. Comparing men and women, the only significant difference found was in the time-averaged mean velocity for the ulnar digital artery (men:5.66 cm/sec vs. women:9.68 cm/sec, P = 0.02) and volume of flow for the ulnar digital artery (men:10.87cc/min vs. women:18.58cc/min, P = 0.03). We found no differences in blood flow parameters comparing participants with and without diabetes.
These data provide a baseline measurement of digital flow hemodynamics that can be used in future studies to model vascular flow after replantation.
目前缺乏腕部和手部的基础血流动力学参数数据。因此，我们旨在使用超声技术量化指动脉和桡动脉的血流参数，并评估患者特征对血流动力学的影响。
我们分析了 2019 年 10 月至 2021 年 12 月期间 25 名患者（50 只手）的超声数据。感兴趣的变量包括桡动脉和食指（IF）掌指横纹处的尺侧和桡侧指动脉的直径及其相应的血流参数。我们使用 Wilcoxon 秩和检验比较了男性和女性以及糖尿病患者和非糖尿病患者之间的变量。
我们的队列包括 18 名女性（36 只手）和 3 名糖尿病患者（6 只手）。IF 桡动脉的平均直径为 7mm，尺侧指动脉的平均直径为 10mm。桡动脉的平均收缩期峰值速度为 21.31cm/sec，尺侧指动脉为 30.03cm/sec。比较男性和女性，唯一发现的显著差异是尺侧指动脉的平均时间流速（男性：5.66cm/sec vs. 女性：9.68cm/sec，P=0.02）和尺侧指动脉的血流量（男性：10.87cc/min vs. 女性：18.58cc/min，P=0.03）。我们没有发现糖尿病患者和非糖尿病患者之间血流参数的差异。
这些数据提供了手部血流动力学的基础测量值，可用于未来的研究中，以模拟再植后的血管血流。
