It is the continuation of the axillary artery beyond the lower margin of teres major muscle.It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow.It then divides into the radial and ulnar arteries which run down the forearm.
During the routine dissection and teaching for the medical undergraduate students at our institute, we observed high bifurcation of radial and ulnar artery from the brachial artery at the mid shaft of the humerus near the insertion of coracobrachialis unilaterally on the right side in a 55 year old male cadaver. Recent data have emphasized that HiBAB can have major clinical implications including high failure rate and decreased functional patency of an arteriovenous (AV) fistula. According to the literature, the brachial artery might present a deviation from the normal pattern in 20% of the cases. A high division of the brachial artery is an unusually proximal bifurcation of the brachial artery into its ulnar and radial branches in the upper arm. 5.3). High bifurcation of brachial artery(poster presented at 59th National conference of anatomical society of India at Indore) This article reports a case of unilateral high bifurcation of the brachial artery. You can find all of these and many other clear and understandable illustrations in Kenhub's anatomy atlas. In the second cadaver, a unilateral high bifurcation of brachial artery was found in left upper limb and this was at a level nearly middle third of the arm.
The general physicians, surgeons, and radiologists must be mindful to these possible anatomical variations of the brachial artery, in their daily medical diagnostic and therapeutic procedures. Japan's largest platform for academic e-journals: J-STAGE is a full text database for reviewed academic papers published by Japanese societies The brachial artery bifurcates to form the radial artery and ulnar artery in the cubital fossa at the level of the radial neck, below the bicipital aponeurosis 1. UNILATERAL HIGH BIFURCATION OF BRACHIAL ARTERY: A CASE REPORT Ahmed M. Auwal, Adaudu D. Zagga, Samuel A. Asala Correspondence: Department of Anatomy, Faculty of Basic Medical Sciences, College of Health sciences, Usmanu Danfodiyo University, Sokoto, Nigeria. The most common is a high origin of the radial artery (15–20 % of cases). The brachial artery is the main artery of the arm and constitutes the continuation of the axillary artery. The brachial artery supplies blood to the muscles of the upper arm by its branches and to the forearm and hand, by its continuation as the radial and ulnar arteries. 35 Antegrade access is generally avoided due to a higher risk of dissection. High bifurcation of the brachial artery. It gives off two terminal branches, the radial and ulnar arteries. High division of the brachial artery has a deep applied importance especially in the field of vascular surgery and radiology, and the feasibility of this variation should be bore in mind before any vascular surgery in the region of the forearm or while interpreting arterio grams of the upper limb. In this retrospective study, we investigated the incidence of HiBAB.
Variant anatomy more commonly involves the brachial artery, particularly at the elbow. Bronchial Artery Origins. Additionally, the profunda brachii and common interosseous artery originated from the radial artery instead of brachial and ulnar arteries respectively. Purpose: High Brachial Artery Bifurcation [HBB] is a relatively common arterial variation of the upper limb. It is an anatomical variant of the arterial branching pattern of the upper limb. 2011; 30(3):286-9 (ISSN: 1827-1839) Troupis T; Zachariadis M; Troupis G; Polydorou V; Polydorou A; Anagnostopoulou S. Variations of the arterial pattern in the upper limb are quite common in humans.
In the present study, we describe two cases of high bifurcation of the brachial artery. However, high brachial artery bifurcation (HiBAB) is a common anatomic variant, with a prevalence up to 20% and a challenging diagnosis by color Doppler ultrasound. Our aim was to determine the incidence of HBB in chronic renal failure patients undergoing autologous Arteriovenous Fistula [AVF] access formation and investigate the effect on AVF patency. The radial artery may originate at any level from the axillary artery to the elbow (Fig.
