Unusual Radial Artery- A Case Report

The variation of radial artery and its clinical significance had been studied multiple times and we present here another case of radial arterial variation. During routine dissection at gross anatomy lab, we have found a radial artery originated from the upper third of brachial artery and had a superficial course at the arm and proximal forearm in a 72- year- old Caucasian female cadaver. We have discussed the possible embryological explanation of this condition and related clinical implications. This kind of unusual origin and course of radial artery should be kept in mind by all healthcare providers during routine venipuncture, orthopedic and plastic surgeries of the arm, coronary angiographic procedures in radial approach to prevent unwanted complications.
