肝总动脉各分枝的观察(国人腹部血管调查研究之二)

OBSERVATIONS ON THE BRANCHES OF THE COMMON HEPATIC ARTERY

1.作者观察了112例国人肝总动脉各分枝的类型,计有肝总动脉,肝固有动脉,肝右动脉、肝左动脉、肝中动脉、胃十二指肠动脉和胃右动脉等七项内容。2.肝总动脉起于腹腔动脉的占94.64±2.1%,起于肠系膜上动脉的占5.36±2.1%。肝总动脉的分枝为正常型而分为胃十二指肠动脉和肝固有动脉的,占75.00±4.0%;未发肝固有动脉的占19.64±3.7%,未发肝固有动脉和胃十二指肠动脉,而为其它分枝的占5.35±2.1%。3.肝固有动脉分为肝左和肝右动脉的,占63.39±4.5%:分为肝左、中及肝右动脉的占11.61±3.0%,没有肝固有动脉的占25.00±4.0%。4.肝右动脉起于正常肝固有动脉的占70.54±4.3%,起于腹腔肝总动脉的占16.96±±3.5%,共87.50±3.1%。另12.5±3.1%起于其它动脉。副肝右动脉的出现率为8.93±2.6%。肝右动脉的位置及行程与胆道的关系和临床有很大的关系,应注意各种变异,避免误损肝右动脉。肝右动脉位于肝总管后面的百分率,占66.07±4.4%,位于其它位置的占33.93±4.4%。5.肝左动脉起于正常肝固有动脉的,占70.54±4.3%,起于腹腔肝总动脉的占18.75±3.6%,共89.29±3.0%;起于其它动脉的有10.71±2.9%。副肝左动脉的出现率为25.00±4.0%。6.肝中动脉起于肝左动脉的占43.75±4.6%,起于肝右动脉的占30.35±4.3%,起于肝固有动脉的占14.29±3.3%,起于其它动脉的占4.46±1.9%。7.胃十二指肠动脉起于正常肝总动脉的占90.17±2.8%,起于肠系膜上动脉的肝总动脉占4.46±1.9%,起于肝右动脉的占4.46±1.9%。无胃十二指肠动脉的占0.89±0.84%。8.胃右动脉(100例)起于正常肝固有动脉的占31.00±4.6%,起于肝左动脉的占22.00±4.1%,起于胃十二指肠动脉的占25.00±4.2%,另有22.00±4.1%起于其它动脉。

An investigation made on the common hepatic artery of 112 cadavers showedthat the common hepatic artery arises from the coeliac axis in 94.64±2.1%,from the superior mesenteric artery in 5.36±2.1%.It divides into the properhepatic artery and the gastroduodenal artery.The proper hepatic artery dividesinto left and right hepatic arteries in 63.39±4.5%;into left,middle and righthepatic arteries in 11.61±3.0%;it is absent in 25.00±4.7%.The normal righthepatic artery originates from the normal proper hepatic artery in 70.54±4.3%;from the coeliac common hepatic aretry in 16.79±3.5%;the right hepatic arteryarises from the other arteries in 12.50±3.1%;accessory right hepatic arteryis noted in 8.93±2.6%.The normal left hepatic artery arises from the proper hepatic artery in70.50±4.3%;from the coeliac common hepatic artery in 18.75±3.6%.The re-placing type of left hepatic artery is seen in 10.71±2.9%;accessory left hepaticartery is noted in 25.00±4.0%.The middle hepatic artery arises from the lefthepatic artery in 43.75±4.6%;from the right hepatic artery in 30.35±4.3%;from the proper hepatic artery in 14.29±3.3%;the middle hepatic artery arisesfrom the other arteries in 4.46±1.9%.The gastroduodenal artery arises fromthe normal common hepatic artery in 90.17±2.8%;from the superior mesentericartery in 4.46±1.9%;from the right hepatic artery in 4.46±1.9%;it is absentin 0.89±0.84%.The right gastric artery arises from the proper hepatic arteryin 31.00±4.6%;from the left hepatic artery in 22.00±4.1%;from the gastroduo-denal artery in 25.00±4.2%;the right gastric artery arises from other arteriesin 22.00±4.1%.The location and course of the hepatic arteries to the bile ductsystem were discussed.
