A case report of a high brachial artery bifurcation in relation to clinical significance of artificial arteriovenous fistula

Introduction: The brachial artery starts at the inferior border of teres major and ends by dividing into ulnar and radial arteries in cubital fossa region. The radial artery frequently arises at the level of the neck of the radius and runs along the lateral side of the forearm. Case report: During routine teaching for undergraduate medical student of the upper limb, atypical brachial artery bifurcation giving a high origin of the radial and ulnar arteries was found in the right upper limb of a male cadaver. The bifurcation level was proximal to the interchonylayar line. After that, the ulnar artery descends and gives prominent common interosseous artery at the neck of radius. Conclusion: This case report of vascular variability of the upper limb is to alert vascular radiologists and surgeons as well as nephrologist to prepare a modified surgical intervention of arteriovenous fistula in renal haemodialysis. There is always great vascular variability of the upper limb therefore it is important to be aware of anatomical variation and to avoid iatrogenic fault
