摘要
目的:探讨Wistar大鼠腹腔干及其分支动脉的解剖结构,为相关实验中动脉的准确显露及导管的合理选择提供依据.方法:采用血管铸型和大体解剖相结合的方法,对10只成年Wistar大鼠的腹腔干及其分支动脉的起源、行程、毗邻关系、显露方法及在实验中的应用等进行描述,并对其直径、长度进行测量.结果:腹腔干起自膈肌下方腹主动脉的右前方,下行至其中点后转向右前上方,分为三个主要分支:脾动脉、胃左动脉、肝总动脉.Wistar大鼠腹腔干与人类腹腔干类似,但无胆囊动脉.在本组有限的样本中,腹腔干变异较小.结论:本研究描述了腹腔干的局部解剖,并在术中准确的显露了动脉,合理的选择了导管,为涉及腹腔干及其分支动脉相关实验打下了良好的基础.
AIM： To describe and illustrate systematically the anatomy of the Wistar rats to facilitate the selection of catheters and performance of studies in this animal. METHODS： Ten Wistar rats＇ coeliac trunk courses, relationships and applications in experiment were studied using vascular casting and gross anatomy analysis. Their diameter and length were measured with a vernier caliper. RESULTS： The celiac trunk originated at the anterior or right aspect of the abdominal aorta just below the diaphragm pillars, ascended close to the aorta and branched into the common hepatic, left gastric and splenic arteries. It was relatively longer than that in humans, but without noncystic artery. In our limited specimens, there was little variation about the coeliac trunk. CONCLUSION： In this study, we successfully describe the Wistar rat coeliac trunk＇s regional anatomy, measure their diameters and lengths, and facilitate the selection of catheters and performance for future study.
