1 男尸,约50岁,身高175cm,发育正常.解剖操作时,发现副肝左动脉及肝总动脉变异.2 本例的腹腔干,在主动脉裂孔下方5.5mm处发自腹主动脉前壁,其管径为8.9mm,长度17mm,随即分为胃左动脉、脾动脉及副肝左动脉三支血管.胃左动脉行向左上方至胃小弯;脾动脉沿胰的上缘左行至脾门;副肝左动脉起始处管径2.8mm,长度34mm,直接上行至肝门入肝左叶.在腹腔干下方11mm处,由腹主动脉前壁发出一短干,起始处管径10.1mm,长度14mm,即分为肠系膜上动脉和肝总动脉两支血管.肠系膜上动脉起始处管径8.0mm,分支布于小肠及部分结肠;肝总动脉起始处管径6.6mm,长度26.5mm,至十二指肠上部上方又分为胃十二指肠动脉和肝固有动脉.胃十二指肠动脉下行至幽门下缘分支布于胃大弯、胰和十二指肠.肝固有动脉起始处管径5.1mm,长度26.2 mm,上行4mm处发出胃右动脉至胃大弯,肝固有动脉本干向右上方行于肝十二指肠韧带内,至肝门处分为左、右两支入肝.肝右支在人肝门前又发出胆囊动脉,穿经胆囊三角至胆囊.在肝门处观察,副肝左动脉位于肝左、右支的左侧.检查其它腹腔脏器或血管未见异常.3 肝动脉起源的变异并非罕见.据《中国人体质调查》(1986年版)报道,肝总动脉起源于肠系膜上动脉或其它占3.53%,副肝左动脉出现率为11.77%.本例肝的动脉血供有两
1 male corpse, about 50 years old, height 175cm, normal development.Animal anatomical operation, found in the left hepatic artery and hepatic artery variability.2 In this case, the celiac trunk, 5.5mm below the aortic hole from the abdominal aortic anterior wall , Its diameter is 8.9mm, length 17mm, then divided into the left gastric artery, splenic artery and left hepatic artery of the left hepatic artery. Left gastric artery to the left side of the stomach to the curve; splenic artery along the left edge of the pancreas To the spleen door; the diameter of the left hepatic artery at the origin of the accessory hepatic artery is 2.8 mm in diameter and 34 mm in length, directly up to the left hepatic portal hepatic lobe.At 11 mm below the peritoneal cavity, a short dry is made from the anterior abdominal wall of the abdominal aorta, Diameter 10.1mm, length 14mm, which is divided into two superior mesenteric artery and common hepatic artery. The diameter of the superior mesenteric artery at the beginning of 8.0mm, the branch in the small intestine and part of the colon; common hepatic artery diameter 6.6 mm, length 26.5mm, to the top of the upper part of the duodenum is divided into gastroduodenal artery and hepatic artery.Gastroduodenal artery down to the lower edge of pyloric branches in the stomach curved, pancreatic and twelve fingers Intestine. The origin of the hepatic artery was 5.1 mm in diameter and 26.2 mm in length. The right gastric artery to the greater curvature of the stomach was placed 4 mm upstream. Hepatic duodenum ligament, to the hilar and left and right two into the liver.The right branch of the liver in front of the human liver and issued a cystic artery, through the gallbladder triangle to the gallbladder.Observation in the hilar, accessory liver left Arteries are located on the left side of the left and right branches of the liver. No abnormalities were observed in other organs or blood vessels in the abdominal cavity.3 Changes in the origin of the hepatic artery were not uncommon.According to the Chinese Physical Fitness Survey (1986 edition), the common hepatic artery originates in the mesentery The upper arteries or other accounted for 3.53%, the incidence of left hepatic artery was 11.77% .This case of liver arterial blood supply with two
