Abstract
The aim of the following study was to present and comprehensively describe
a case of a bilateral absence of the deep brachial artery (DBA). Furthermore, its
embryology and clinical significance will also be discussed.
During routine dissection, a 71-year-old male cadaver with a bilateral abnormality
in the DBA and its branches was found. The first branch of the brachial artery (BA)
was found to be the radial collateral artery, which passed behind the radial nerve.
Furthermore, the middle collateral artery originated distal to the radial collateral
artery and gave off first a singular, minor muscular branch and then the superior
ulnar collateral artery. Later, the preceding nutrient arteries of the humerus and
the deltoid branch consecutively branched off from the middle collateral artery.
Subsequently, the middle ulnar collateral artery, the inferior ulnar collateral artery,
the deltoid artery, the radial artery, and the ulnar artery branched off from the
BA, as adapted in the current knowledge regarding the anatomy of the upper
extremity. Furthermore, detailed measurements of the distances between the
mentioned arteries were carried out.
In the present study, a bilateral absence of the DBA was demonstrated. Meta-analysis
focusing on the anatomy of this artery has shown how variable its characteristics
are. However, our case report is the first in the literature to present this extremely
rare variation. Having adequate knowledge regarding the anatomy of the arteries
of the proximal arm is of immense importance when performing orthopaedic
and reconstructive surgeries in this area.
