【摘要】 目的：研究主动脉弓畸形及其临床意义。方法：在历时１５ 年对３２０ 例主动脉弓的解剖中，发现４ 例主动脉弓畸形，并对此弓变异及其周围诸结构进行解剖和观察。结果：在４ 例主动脉弓畸形的病例中，２ 例为右食管后锁骨下动脉并存右非喉返神经，另２ 例为右主动脉弓并存左食管后锁骨下动脉或左背主动脉分离。食管后锁骨下动脉起始部形成憩室，可产生食管受压性咽下困难。左锁骨下动脉或左背主动脉经动脉导管连接或发自左肺动脉，可形成先天性肺动脉—锁骨下动脉窃血症。结论：主动脉弓畸形在临床实践中具有意义，它的发生有其胚胎学基础。更多还原

【Abstract】 To investigate the aortic arch deformity and its clinical importance.Methods:In 320 specimens,4 cases of aortic arch deformity were observed during 15 years of anatomical studies,and careful dissections were made to reveal the surrounding structure.Results:In the two cases,right retro esophageal subclavian a.coexisted with right nonrecurrent laryngeal nerve.In the other two cases,right aortic arch coexisted with left retro esophageal subclavian a.or left dorsal aorta separation.Conclusion:The aortic arch deformity showed significance in clinical practice.更多还原
