Unilateral accessory brachial artery: A case report with embryological background and review of the literature.

ABSTRACT:

Introduction

The accessory brachial artery is a rare arterial variation of the upper limb. It was observed in 0.1-0.8% of upper extremities. In comparison with the brachial artery, the accessory brachial artery has a narrow caliber.

Case presentation

During dissection of an old African male cadaver, the brachial artery was observed bifurcating into accessory brachial artery medially and main brachial artery laterally. These two arteries then rejoined in the cubital fossa, forming a common stem, which bifurcated directly into radial and ulnar arteries.

Clinical discussion

Detailed knowledge about such arterial variation is clinically essential for angiographic images evaluation, trans-ulnar or trans-radial coronary catheterization, venipuncture, traumatic
