【摘要】：目的观测家兔胸导管的形态学结构,改进灌注方法,丰富实验动物资料,为临床应用提供参考。方法解剖30例新鲜完整家兔尸体,观测胸导管的起始、走行及毗邻结构,用改良后的过氯乙烯、丙酮、乙酸乙酯及显色剂体积比例为1∶1∶2∶1的灌注剂进行灌注制成标本。结果家兔胸导管走行正常22例(84.6%),其注入左颈外静脉,10例(38.5%)注入点在平对T1椎体处,另12例(46.2%)注入点在T1椎体和T2椎体之间。注入点存在变异4例(15.4%),注入左前腔静脉1例(3.8%),注入左颈总静脉3(11.5%)例。存在乳糜池结构3例(11.5%),瓣膜结构2例(7.7%)。结论家兔胸导管走行多变异,在颈段注入点处为多。
[Abstract]:Objective to observe the morphological structure of rabbit thoracic catheter, improve the perfusion method, enrich the experimental animal data and provide reference for clinical application. Methods Thirty fresh intact rabbit cadavers were dissected. The origin, course and adjacent structure of thoracic catheters were observed, and the modified perchloroethylene and acetone were used. The volume ratio of ethyl acetate to chromogenic agent was 1: 1: 2: 1. Results there were 22 cases (84.6%) with normal thoracic catheterization. 10 cases (38.5%) were injected into the left external jugular vein and the other 12 cases (46.2%) were injected between the T1 and T2 vertebrae. There were 4 cases (15.4%) with variation of injection point, 1 case (3.8%) with left anterior vena cava and 3 cases (11.5%) with left common jugular vein. The structure of chylous cistern was found in 3 cases (11.5%) and valvular structure in 2 cases (7.7%). Conclusion there are many variations in the thoracic ducts in rabbits, and there are many injection points in the cervical segment.
