BILATERAL PRESENCE OF MULTIPLE VARIANT UPPER LIMB ARTERIES: A CADAVERIC CASE REPORT

Anatomical variations of upper limb arteries are varied and relatively frequent. These include the median ar­tery and the brachioradial artery, among others. Coexis­tence of these variations together has been described previously, yet we believe this study is the first to report on the bilateral occurrence of both. The reason for the lack of previous reports on such bilateral variation is un­known, especially given the fact that some studies report the incidence of these variations individually exceeding 10% and 40% for the brachioradial and the median arte­ries, respectively. In our case, both of the brachioradial arteries anastomosed with the brachial arteries in the cu­bital fossa, later following the course usual for the radial artery. Meanwhile, the median nerves on both sides were followed by median arteries, with the right one piercing the median nerve and finally supplying the structures of the hand with blood. Physicians’ knowledge of such va­riations and their coexistence is essential for providing better patient care, as these arteries have been associated with specific clinical challenges.
