ABSTRACT

BACKGROUND:

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.

METHODS:

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.

RESULTS:

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 (men5.66 cm/sec vs. women9.68 cm/sec, P = 0.02) and volume of flow for the ulnar digital artery (men10.87cc/min vs. women18.58cc/min, P = 0.03). We found no differences in blood flow parameters comparing participants with and without diabetes.

CONCLUSION:

These data provide a baseline measurement of digital flow hemodynamics that can be used in future studies to model vascular flow after replantation.
