摘要
目的:研究动脉导管三角区,为动脉导管结扎术提供形态学依据。方法:在尸体标本上模拟动脉导管结扎术操作步骤对动脉导管三角进行解剖,并对相关结构进行观察测量,结果进行统计学处理。结果:左支气管动脉在动脉导管下窗发自降主动脉的占28.6%(4例),在动脉导管上窗发自主动脉弓的占7.1%(1例),动脉韧带长(11.1±1.4)mm,主动脉峡部外径(21.9±2.1)mm,二者之比为0.49±0.05,有直线相关性(r=0.892,P<0.001)。左喉返神经跨越动脉韧带的主动脉侧1/3者占57.2%,中间1/3及肺动脉侧1/3者均为21.4%。结论:熟悉动脉导管三角的解剖结构及其量化关系,有助于更好地避免动脉导管结扎术中并发症的发生。
Objective: To explore the anatomical features of the ductus arteriosus triangle and provide morphologic data for ligation of ductus arteriosus . Methods: The anatomic study on 14 cadavers was taken and the aim mainly focused on the originating site of the left bronchial artery from the aorta and the site where the left recurrent laryngeal nerve override the arterial ligament. Results: In the 14 cadavers, 28.6%(4 cases) were found that left bronchial artery originated from the infra-arterial ligament cava and 7.1%(1 case)from the super-arterial ligament cava. Left recurrent laryngeal nerve were found override the arterial ligament near the aorta in 8 cases as well as that over the middle of the arterial ligament and that near the pulmonary artery in 3 cases respectively. The arterial ligament length had a ratio of 0.490.05 comparing with the diameter of the aorta and they showed a linear relationship(r=0.892, P<0.001). Conclusions:With more understanding to the anatomical feature of the ductus arteriosus triangle, complications of ligation of ductus arteriosus can be avoided effectively.
