Hepatomesenteric trunk and gastro-splenico-phrenic trunk

A thorough knowledge of variation in the branching pattern of celiac trunk and superior mesenteric artery is important for surgeons, radiologists and other medical specialties. We observed some variations in the branching pattern of celiac trunk and superior mesenteric artery during dissection classes for first year medical students. The celiac trunk (gastro-splenico-phrenic trunk) divided into inferior phrenic trunk, left gastric and splenic arteries. The inferior phrenic trunk divided into right and left inferior phrenic arteries. The common hepatic artery took its origin from a hepatomesenteric trunk and passed behind the portal vein and bile duct. It hooked around the bile duct and then divided into three branches; hepatic artery proper, gastroduodenal artery and supraduodenal artery
