title: [Anatomic variations of the hepatic artery : a study of 33 cases and review].
abstract: BACKGROUND
  The hepatic artery is prone to numerous anatomic variations dictated by certain variables of the organogenesis. Aim : To research study the anatomic variations of the hepatic artery as well as their implications within surgical practice.
  
  
  METHODS
  Study of a post-mortem series of 33 cases of dissection of the hepatic pedicle with fresh corpses (deaths amounting no longer than 24 hours), carried out in conditions that are quite close to those met with the living ones.
  
  
  RESULTS
  The common hepatic artery was divided at the foot of the hepatic pedicle into a gastro duodenal artery and into a proper hepatic artery in 94% of the cases. In 6% of the cases, we noticed a three level change, a branching of the average hepatic artery into a gastro duodenal artery, a right hepatic artery and a left hepatic artery. The proper hepatic artery represented the pedicle segment of the hepatic artery in 94% of the cases. In 36% of the cases, the liver was irrigated by two hepatic arteries. In 12% of the cases, there was the matter of the right hepatic artery, branch of the mesenteric artery. In 24% of the cases, there was the matter of the left hepatic artery branch of the left gastric artery.
  
  
  CONCLUSIONS
  The perfect knowledge in preoperative and preoperative stages of the anatomic variations of the hepatic pedicle is quite essential. Actually, the lack of knowledge of these variations exposes to the risk of certain complications which are sometimes deadly during hepatic transplants, pancreatic surgery, cholecystectomies, through laroscopic way as well as in the treatment of gastro-esophagus surging.
