Abstract
Background: The incidence of arterial variations in the upper limb is variable among ethnic groups. However, there are only a few studies on the Asian population, particularly in China.
Objective: This research provided the first large data series on arterial variations in the upper limb of Chinese adults.
Methods: In this observational study, the arteries in the upper limb of consecutive patients were analyzed between July 2020 and June 2021, and the hemodynamic variables of each patient were collected.
Results: The brachial artery deviated in 6.60% of upper limbs (11.89% of patients), and the brachioradial artery (BRA) was the most frequent variation. In the wrists of all patients, the volume flow (VF) of the BRA was lower than that of the radial artery (RA). Besides, the VF of the BRA in patients with end-stage renal disease (ESRD) was lower than that in those without ESRD in the wrist. Additionally, in the forearms of patients without ESRD, the VF of the BRA was lower than that of the RA. In the upper arm of patients with ESRD, the VF of the brachial artery in patients with BRA was significantly lower than that in patients with RA.
Conclusion: The incidence of arterial variations in the upper limb of Chinese adults was 6.60% (limbs) or 11.89% (patients) in this study. In our investigation, the BRA was the most common high bifurcation of the brachial artery type. Furthermore, the Chi-squared test revealed significant differences in the distribution, which was common in the right upper limb but not in sex.
期刊介绍：
Technology and Health Care is intended to serve as a forum for the presentation of original articles and technical notes, observing rigorous scientific standards. Furthermore, upon invitation, reviews, tutorials, discussion papers and minisymposia are featured. The main focus of THC is related to the overlapping areas of engineering and medicine. The following types of contributions are considered:
1.Original articles: New concepts, procedures and devices associated with the use of technology in medical research and clinical practice are presented to a readership with a widespread background in engineering and/or medicine. In particular, the clinical benefit deriving from the application of engineering methods and devices in clinical medicine should be demonstrated. Typically, full length original contributions have a length of 4000 words, thereby taking duly into account figures and tables.
2.Technical Notes and Short Communications: Technical Notes relate to novel technical developments with relevance for clinical medicine. In Short Communications, clinical applications are shortly described. 3.Both Technical Notes and Short Communications typically have a length of 1500 words.
Reviews and Tutorials (upon invitation only): Tutorial and educational articles for persons with a primarily medical background on principles of engineering with particular significance for biomedical applications and vice versa are presented. The Editorial Board is responsible for the selection of topics.
4.Minisymposia (upon invitation only): Under the leadership of a Special Editor, controversial or important issues relating to health care are highlighted and discussed by various authors.
5.Letters to the Editors: Discussions or short statements (not indexed).
