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

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.
