Bilateral Variation of Radial Artery: Two Case Reports and Literature Review

Abstract

The radial artery is useful in interventional treatment, and its variation is important for the clinician consideration. During the dissection of Sudanese adult 83-old-male cadaver, multiple upper limbs, a rare vascular variation, was observed in cases 1 & 2. The axillary arteries in both limbs showed a pattern of many variations, the radial arteries have been arising directly from their second part in the axilla. They were run through the arm superficially, along with their courses, they were separated from the brachial artery. In the right limb, a communicated artery was seen connecting the radial and brachial arteries at the region of the cubital fossa. However, their courses of the radial artery in the forearm and hand were found normal. Knowledge of anatomical variation of the radial artery is essential in performing the transradial coronary procedure.
