The radial artery is commonly originated from the brachial artery in the cubital fossa at the level of the neck of the radius. It is the artery of choice for coronary artery angiography, percutaneous coronary artery intervention, cannulation, and others. Radial artery anomalies like high origin, tortuosity, and accessory branches are associated with the failure of such procedures. The main objective of this study is to study the variation in origin and course of the radial artery in cadavers.
A descriptive cross-sectional study was conducted in 27 formalin-fixed adult human cadavers in the Department of Anatomy, KIST Medical College and Teaching Hospital, Lalitpur, Nepal, from 2075/4/2 to 2076/4/2. Ethical approval was taken on date 02/04/2075 (IRC No. 2074/75/38). Altogether, 53 specimens were enrolled in the study by convenience sampling method. Point estimate at 95% Confidence Interval was done for binary data along with frequency and proportion. The data was analyzed by and Statistical Package for the Social Sciences version 20.
Out of of 53 upper limbs, forty-six (86.79%) specimens, the origin of the radial artery was observed to be normal in the cubital fossa, 34.5±6.31mm below the level of the intercondylar line of the humerus with the superficial course. In seven (13.21%) specimens, the radial artery showed variation in the origin. Among them, variations in origin were found to be from sites like the axilla, upper-middle, and lower part of the arm. One cadaver showed a tortuous radial artery bilaterally.
This study concludes that most of the radial artery originates in the cubital fossa from the brachial artery with few variations.
桡动脉通常起源于肘窝处桡骨颈水平的肱动脉。它是冠状动脉造影、经皮冠状动脉介入治疗、插管等手术的首选动脉。桡动脉异常，如高位起源、迂曲和分支异常，与这些手术的失败有关。本研究的主要目的是研究尸体中桡动脉起源和走行的变异情况。
2075年4月2日至2076年4月2日，在尼泊尔拉利特布尔KIST医学院和教学医院解剖学系对27具福尔马林固定的成年人体尸体进行了描述性横断面研究。于2075年4月2日获得伦理批准（IRC编号2074/75/38）。通过便利抽样法共纳入53个标本进行研究。对二元数据进行了95%置信区间的点估计以及频率和比例分析。数据采用社会科学统计软件包第20版进行分析。
在53条上肢中，46条（86.79%）标本的桡动脉起源于肘窝，在肱骨髁间线水平以下34.5±6.31mm处，走行表浅。7条（13.21%）标本的桡动脉起源存在变异。其中，起源变异的部位有腋窝、上臂中下部等。1具尸体双侧桡动脉迂曲。
本研究得出结论，大多数桡动脉起源于肘窝处的肱动脉，变异较少。
