摘　　要：目的探讨小猪小肠移植时供体、受体和最佳血管的选择。方法麻醉,先后称量30头小猪及其小肠的体重与长度,测算两者比例关系;对离体小肠行造影、色料灌注、X线摄片,观测腹主动脉、肠系膜血管及其分支在体和离体的分布情况。结果小肠的长度平均为体长的11.5倍;小肠的重量平均为体重的2.3%。腹主动脉和肠系膜前动脉近段在体与离体灌注后血管外径分别为4.3/4.6mm和2.5/2.7mm左右,肠系膜前静脉较肠系膜前动脉粗1～2mm。肠系膜前动脉水平段分支多为6～8支。一般第5、6支最长[(20.0±7.0)mm和(22.0±8.2)mm],在体与离体血管外径分别达到1.9、2.2mm左右。结论腹主动脉、近段肠系膜前动脉及其第5、6分支水平肠系膜前动脉可以分别作为小猪全小肠和节段小肠移植的首选血管;在实行节段小肠移植时,可以利用肠管长度比例系数,进行初步筛选实验动物。Objective To study the anatomy of the small intestine, and investigate the optimal selection of donors, recipients, and their small intestine vessels in piglet small intestine transplantation. Methods The weight and length of 30 piglets were measured. Angiography and pigments perfnsion were used to observe the main vessels of the small intestine, and the length of the small intestine, and the external diameter of the main vessels of the small intestine were measured in vivo and ex vivo. Results The length of the small intestine was 11.5 times as long as the body length, and its weight accounted for 2. 3% of the body weight. The outer diameters of abdominal aorta （AT）, mesenterie anterior artery（MAA） and its 5^th-6^th branches in vivo and ex vitro were 4.3/4.6mm, 2. 5/2.7mm and 1.9/2.2mm respectively. The total number of MAA＇s branches was 6 ～ 8 in general and its 5^th～6^th branches were the longest [ （20.0 ± 7. 0） mm, （22.0 ± 8. 2） mm]. The outer diameter of mesenterieal anterior vein （MAV） was 1～2 ram wider than that of MAA. Conclusions AT, MAA and its 5^th～6^th branches are the preferable vessels for small intestine transplantation. In segmental small intestine transplantation, the length of the small intestine and body weight can be used to primarily select the suitable animals.
