主动脉弓离断的超声误诊分析

正主动脉弓离断(interruption of aortic arch,IAA)是主动脉弓的两个节段之间或主动脉弓与降主动脉之间的管腔完全失去解剖上的连续性,或仅由闭锁的纤维束条相连,而无直接的血液相通。因血流动力学影响严重、预后差,未及时治疗,75%多于出生后1个月死亡,90%在1年内死亡~(1]),因此早期诊断及手术非常

Analysis of Misdiagnosis Interruption of Aortic Arch

Abstract: Objective This paper analyzes the reason of the ultrasonic misdiagnosis of aortic arch and discusses the diagnostic thinking, methods and experience. Methods A retrospective analysis was performed on 5 cases of aortic arch isolated from preoperative ultrasonography or reexamination. Results The 5 cases of misdiagnosis were confirmed by surgery, angiography and double-source CT, of which 3 were type A, 2 cases B, and the sonogram had commonness, which was different from the combination of malformation.Two cases were combined with ventricular septal defect. One case of the main pulmonary artery septal defect and the right pulmonary artery anomaly originated from the ascending aorta, and one case of isolated aorticarch was broken. Conclusion Ultrasound examination, discovered that the ascending aorta and aortic arch drop small diameter developing, pulmonary artery significantly broadening, pulmonary hypertension and heart malformations don''t match, should be alert to the aortic arch is broken possible, carefully check the aortic arch.
