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 evaluate the anatomic characteristics of beagle celiac artery and its major branches by multi-slice spiral CT angiography (MDCTA) and digital subtraction angiography (DSA). Methods Fifteen adult Beagle dogs were examined by multi-slice spiral CT (MDCT) and selective celiac artery cannulation and DSA angiography via superficial branch of femoral artery under direct vision to observe the origin and movement of the main branch of celiac trunk And measure the diameter and length. Results Fifteen beagle dogs were successfully cannulated with 15 femoral arteries. The success rate was 100% (15/15). The successful rates of celiac artery, left gastric artery, common hepatic artery and splenic artery catheterization were all 100% (15/15). Beagle dogs celiac artery anatomy is very similar to humans. MSCT and DSA examination found that human celiac artery anatomy and the same point is that: (1) the initial part of the celiac artery in the lumbar vertebral body level; (2) the celiac artery issued by the anterior abdominal wall after walking forward, And then issued a branch; (3) Although the left gastric artery issued by the proximal splenic artery, but still belong to the celiac artery branch, so the three major branches of the celiac artery, common hepatic artery and left gastric artery. The difference is that: (1) the left gastric artery from the proximal splenic artery; (2) Gastroduodenal artery in the part of the hilar, the hepatic artery is very short or absent. Three dogs, the right hepatic artery, sent 20% before the gastroduodenal artery. Conclusion The similarities between the beagle dogs celiac artery and human celiac artery anatomy have broad application prospects for animal intervention in the liver, spleen, pancreas and stomach.
