摘　　要：目的采用多层螺旋CT血管造影(MDCTA)和数字减影血管造影(DSA)评价比格犬腹腔动脉及其主要分支的解剖学特点。方法成年比格犬15只,分别进行多层螺旋CT(MDCT)检查和在直视下行经股动脉浅表分支选择性腹腔动脉插管及DSA造影术,观察腹腔干其主要分支的起源和走行并测量直径和长度。结果 15只比格犬15条股动脉插管成功,成功率为100%(15/15)。腹腔动脉、胃左动脉、肝总动脉、脾动脉插管造影成功率均为100%(15/15)。比格犬腹腔动脉解剖与人类很相似。MSCT和DSA检查发现其与人类腹腔动脉解剖的相同点在于:(1)腹腔动脉起始部位在第1腰椎体中上水平;(2)腹腔动脉由腹主动脉前壁发出后向前走行,然后再发出分支;(3)虽然胃左动脉由脾动脉近段发出,但是仍属于腹腔动脉分支,所以腹腔动脉三大分支肝总动脉、脾动脉和胃左动脉与人类相同。不同点在于:(1)胃左动脉发自脾动脉近段;(2)胃十二指肠动脉在肝门部分出,肝固有动脉很短或缺如。3只犬肝右动脉在胃十二指肠动脉之前发出20%。结论比格犬腹腔动脉与人类腹腔动脉解剖的相似性,对肝、脾、胰、胃等脏器的动物介入性研究具有广阔的应用前景。Objective To assess the anatomical features of beagle＇s celiac artery by multidetector CT angi- ography （MDCTA） and digital subtraction angiography （DSA）. Methods 15 adult beagles were examined by multidetector CT （MDCT）. Celiac artery was catheterized via a superficial branch access of femoral ar- tery and performed selective angiography. Results MDCT and angiography were performed successfully in all animals, with a success rate of 100%（15/15）. Beagle＇s celiac artery anatomy is very similar to the hu- man＇s. Similarities between the beagle＇s and human celiac artery anatomy revealed by MSCT and DSA in- clude： （1） The celiac artery arises from the aorta at the same level; （2） After arising from the anterior wall of the aorta, the celiac artery runs forwardly and gives branches; （3） Although Left gastric artery ari- ses from the proximal splenic artery in beagle, it is still a branch of the celiac artery , therefore, three branches of celiac artery, the hepatic artery , splenic artery and left gastric artery were the same with hu- man＇s. The differences are： （1） Left gastric artery arise from the proximal splenic artery; （2） Gastroduo- denal artery arise at the liver hilar. The proper hepatic artery is very short or absent. In 3 dogs, right he- patic artery rises before the gastroduodenal artery （20%）. Conclusion The study confirms anatomical similarity between the beagle＇s celiac artery and the human celiac artery. It has broad application prospects in animal interventional studies of the liver, spleen, pancreas, stomach and other organs.
