【摘要】：目的探讨产前超声诊断胎儿右位主动脉弓并右位动脉导管的价值。方法回顾分析11胎右位主动脉弓并右位动脉导管的胎儿超声心动图特征,重点观察三血管气管切面主动脉弓与肺动脉动脉导管的连接形态、主动脉弓和动脉导管与气管的位置关系。结果右位主动脉弓并右位动脉导管时,主动脉弓和动脉导管均位于气管的右侧,呈反向的"V"型连接,即主动脉弓和动脉导管仍呈"V"型连接,但位于气管的右侧。所有11胎右位主动脉弓并右位导管胎儿均不伴迷走左锁骨下动脉,未形成血管环。结论胎儿右位主动脉弓并右位导管的诊断切面为三血管气管切面,但不表现为右位主动脉弓并左位导管时特征性的"U"型连接,诊断的关键在于仔细观察主动脉弓和动脉导管与气管的位置关系。
[Abstract]:Objective to evaluate the value of prenatal ultrasound in the diagnosis of right aortic arch and right artery catheter. Methods the characteristics of fetal echocardiography of 11 fetuses with right aortic arch and right artery catheter were analyzed retrospectively, and the connection between aortic arch and pulmonary artery ductus was observed. The relationship between aortic arch and ductus arteriosus and trachea. Results the aortic arch and ductus arteriosus were located on the right side of the trachea, which was the reverse "V" type connection, that is, the aortic arch and the ductus arteriosus were still connected in the "V" type, but they were located on the right side of the trachea. All 11 fetuses with right aortic arch and right catheterization did not follow the left subclavian artery and formed no vascular ring. Conclusion the diagnosis plane of right aortic arch with right catheter in fetus is three-vessel tracheostomy, but it does not show the characteristic "U" connection of right aortic arch and left position catheter. The key to diagnosis is to carefully observe the location of the aortic arch and catheter with the trachea.
