Anomalous origin of the deep brachial artery (profunda brachii) observed in bilateral arms: case report

Abstract

During an ordinary dissection, a cadaver showed a bilateral anomalous origin of the deep brachial artery, where this vessel appeared like a branching of the subscapular artery with common trunk, which included the posterior circumflex humeral artery. The course and distribution of the deep brachial artery in the back compartment were relatively consistent with previous reports. Arterial variations can be damaged through iatrogenic means if not properly documented. The knowledge of this case is very important in clinical medicine and in surgeries in this compartment to prevent any injury.Keywords: deep brachial artery; anatomical variation; surgery. ResumoDurante dissecação em prática usual, um cadáver apresentou origem anômala da artéria braquial profunda, na qual este vaso apareceu como um ramo da artéria subescapular com um tronco comum, que incluiu a artéria circunflexa posterior do úmero. O curso e a distribuição da artéria braquial profunda no compartimento posterior foram relativamente coincidentes com relatos prévios. Variações arteriais podem ser danificadas de maneira iatrogênica se não forem adequadamente documentadas. O conhecimento desse caso é muito importante na prática clínica e em cirurgias nesse compartimento para prevenção de qualquer injúria.Palavras-chave: artéria braquial profunda; variação anatômica; cirurgia.

Output Relations of Humeral Circumflex Arteries and its Variations

“…Variations in the branching patterns of the major arterial trunks have been reported with an incidence of over 20% in human adult limbs (Rodríguez-Niedenfuhr et al, 2001;de Paula et al, 2013). Despite this, several variations in its origin and in the course of the AA, like other vessels of the upper limb, could be considered.…”
