Advances in clinical diagnosis and treatment of double aortic arch / 国际儿科学杂志

ABSTRACT

Double aortic arch is a congenital aortic arch malformation, which is caused by abnormal development of the fourth aortic arches during embryonic development.The patient with double aortic arch has no specific symptoms.It often encircles the trachea and esophagus.In severe cases, it causes dyspnea and dysphagia, and even endangers life.Currently, double aortic arch is diagnosed mainly by imaging techniques, such as echocardiography, computed tomography angiography, magnetic resonance angiography, cardiac catheterization.The main treatment is surgery.Therefore early diagnosis and treatment are very important to avoid tracheomalacia and improve the prognosis.This article will briefly review the research progress of embryonic development mechanism, classification, clinical diagnosis, treatment and prognosis of double aortic arch, aiming to improve the physician′s skills of diagnosis and treatment.
