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。
1. The authors looked at the types of branches of the common hepatic artery in 112 Chinese, including the common hepatic artery, the hepatic artery, the right hepatic artery, the left hepatic artery, the middle hepatic artery, the gastroduodenal artery, and the right gastric artery Seven items. Hepatic artery in the celiac artery accounted for 94.64 ± 2.1%, from the superior mesenteric artery accounted for 5.36 ± 2.1%. The branches of the common hepatic artery were of normal type and divided into gastroduodenal artery and hepatic artery, accounting for 75.00 ± 4.0%. The non-hepatic artery accounted for 19.64 ± 3.7%, without hepatic artery and stomach ten The duodenal artery, while for other branches accounted for 5.35 ± 2.1%. 3. The hepatic artery was divided into left hepatic and right hepatic artery, accounting for 63.39 ± 4.5%: 11.61 ± 3.0% were divided into left, middle and right hepatic artery, and 25.00 ± 4.0% without hepatic artery. Right hepatic artery in normal hepatic artery accounted for 70.54 ± 4.3%, from the common hepatic artery accounted for 16.96 ± 3.5%, a total of 87.50 ± 3.1%. The other 12.5 ± 3.1% from other arteries. The incidence of accessory right hepatic artery was 8.93 ± 2.6%. Right hepatic artery location and stroke and the relationship between biliary and clinical have a great relationship, should pay attention to various variations, to avoid damage to the right hepatic artery. Right hepatic artery in the right hepatic duct behind the percentage, accounting for 66.07 ± 4.4%, 33.93 ± 4.4% located in other locations. The left hepatic artery originated from the normal hepatic artery, accounting for 70.54 ± 4.3%, accounting for 18.75 ± 3.6% of the total peritoneal hepatic artery, with a total of 89.29 ± 3.0%. From other arteries, there was 10.71 ± 2.9%. The incidence of the left accessory hepatic artery was 25.00 ± 4.0%. 6. The middle hepatic artery accounts for 43.75 ± 4.6% of the left hepatic artery, 30.35 ± 4.3% of the right hepatic artery, 14.29 ± 3.3% of the native hepatic artery, and 4.46 ± 1.9 from other arteries %. Gastroduodenal artery from the normal hepatic artery accounts for 90.17 ± 2.8%, from the superior mesenteric artery of the common hepatic artery accounted for 4.46 ± 1.9%, from the right hepatic artery accounted for 4.46 ± 1.9%. No gastroduodenal artery accounted for 0.89 ± 0.84%. Right gastric artery (100 cases) from normal hepatic artery accounted for 31.00 ± 4.6%, from the left hepatic artery accounted for 22.00 ± 4.1%, from the gastroduodenal artery accounted for 25.00 ± 4.2%, and the other There are 22.00 ± 4.1% from other arteries.
