Introduction: Double aortic arch (DAA) is a congenital anomaly of the aortic arch. It is the most common type of complete vascular ring. When it occurs, the connected segment of the aortic arch and its branches encircle the trachea and esophagus, leading to symptoms related to these two structures. Case Report: We present a case of a newborn baby who developed biphasic stridor immediately after...

Two children presented with symptoms suggestive of a vascular ring. Barium esophagrams in each case showed a posterior impression caused by a retroesophageal aortic arch. Angiographic studies defined a rare form of vascular ring resulting from an ascending left-sided aorta, a descending right-sided aorta and a right-sided ligamentum arteriosum. At surgery, the diagnosis was confirmed and the an...

In this case report, we present an infant who has a double aortic arch vascular ring anomaly. We emphasize the importance of maintaining a high level of clinical suspicion for vascular ring when evaluating an infant with the symptom of persistent stridor. Recognizing persistent stridor early and treating the underlying cause can, indeed, optimize outcomes. Case A 3-day-old boy presented to the ...

A 36-year-old male patient with no remarkable medical history was admitted to our hospital for a health check up. On chest radiography, bilateral aortic notches at the level of aortic arch were shown suggesting aortic arch anomaly without any clinical symptoms. Two aortic arches were almost same-in-size on suprasternal view of transthoracic echocardiography. In addition, multidetector computed ...

A case of Wolff-Parkinson-White syndrome type A with coexisting ipsilateral bundle branch block is presented. The diagnosis was suspected because of subtle electrocardiographic changes and was confirmed at electrophysiological study. Necropsy showed a vascular anomaly of the coronary sinus that contained bundles of myocardial muscle which crossed the atrioventricular ring at a site that was con...

objective : double aortic arch (daa) is a rare congenital malformation. strategies for diagnosis and treatment are different. thoracoscopic treatment of daa is limited to case reports or little case series. we report a description of our diagnostic and therapeutic approach and evaluate outcomes. methods: we reviewed charts of infants with double aortic arch who were hospitalized in our departme...
