Summary
During the dissection of a 48-year-old male cadaver, the left gastric artery was observed directly originating from the abdominal aorta. An unusual embryologic development of the ventral splanchnic arteries may lead to considerable variations. The rare occurrence of this variation is stated to be 0.5% – 15%. This case of the left gastric artery is described in detail, especially its point of emergence which may be important in operative procedures on the supracolic organs, in stomach resection, and during dissection of lymph nodes along this artery in gastric cancer.
Résumé
Lors de la dissection d'un sujet masculin de 48 ans, on observe la naissance de l'artère gastrique gauche directement de l'aorte. Le développement embryologique anormal des artères splanchniques ventrales peut entraîner des variations considérables. La survenue de cette rare variation est estimée à une fréquence de 0,5 % à 15 %. Ce cas d'artère gastrique gauche est décrit en détail, en raison de son importance dans les techniques chirurgicales concernant les organes sus-mésocoliques, en particulier pour les résections gastriques et lors des curages ganglionnaires sur le trajet de cette artère lors de cancer gastrique.
