Abstract

A case report of multiple variations involving the arteries of the upper limb in a single cadaver is presented. In addition to the proximal origin of the arteries unusual arterial patterns on both the right and left sides were present. On the right side, the subscapular artery gave rise to a large posterior circumflex humeral artery in addition to the thoracodorsal and circumflex scapular arteries. On the left side, the radial and ulnar arteries arose from the brachial artery at the level of arm, with their origins being opposite to the usual arrangement. There was an arciform anastomosis between the radial and ulnar arteries, with the radial recurrent artery arising from the concavity of the arch. The course of both the radial and ulnar arteries was normal at the wrist and hand, except for the absence of the first palmar metacarpal artery and an early bifurcation of the second palmar metacarpal artery.

Résumé

Nous rapportons un cas de variations multiples intéressant les artères du membre supérieur rencontrées sur le même cadavre. En plus de l'origine proximale des artères, on trouvait une disposition inhabituelle des côtés droit et gauche. A droite, l'artère subscapulaire abandonnait une volumineuse artère circonflexe humérale postérieure en plus de l'artère thoraco-dorsale et de l'artère circonflexe de la scapula. Du côté gauche, les artères radiale et ulnaire naissaient de l'artère brachiale au niveau du bras et leurs origines étaient disposées inversement à la disposition habituelle. Les artères radiale et ulnaire étaient reliées par une anastomose arciforme. L'artère récurrente radiale naissait de la concavité de cette arche. Les artères radiale et ulnaire avaient un trajet normal au poignet et à la main, à l'exception de l'absence de la première artère métacarpienne palmaire et de la bifurcation précoce de la deuxième artère métacarpienne palmaire.
