N2  - Variations in the normal arterial anatomical pattern are very common and among them the high origin of the radial artery is the most frequent variation. We report two cases of a unilateral high-origin radial artery with different variations in each case in the course of the artery, along with a review of the literature. From an embryological point of view, the presence of a radial artery of high origin is established by developmental stage 18 and may be due to a differentiated hemodynamic predominance of the deep arterial segments over the superficial arterial network, chemical factors, foetal position in the uterus, developmental arrest in early stages, and genetic predisposition. Additionally, a high-origin radial artery may complicate medical procedures, leading to misdiagnosis and easier injury. Finally, we discuss the terminology problem we came across reviewing the literature because a number of studies refer to this variant using different terms.
