 A double aortic arch (DAA) is a congenital anomaly of the aortic arch, which is also the most common type of complete vascular ring. This vascular ring can compress the trachea and esophagus, as well as cause respiratory, gastrointestinal, and cardiac symptoms.

 In the present case report, a 10-year-old boy with recurrent cough, fever, shortness of breath, chest pain, and a history of recurrent respiratory infections was examined. According to the results of bronchoscopic evaluation, he was found to have a localized tracheomalacia. DAA and dextrocardia condition were also confirmed for this patient by performing a computed tomography angiography of the thorax and the three-dimensional reconstruction of CT angiography.

 The diagnosis of double aortic arch may be confused with upper respiratory tract infections or foreign body aspiration. Therefore, it was recommended that a particular attention should be paid to the double aortic arch when evaluating cases of stridor in children with unknown causes or recurrent respiratory infections. CT angiography and cardiac MRI were the diagnostic methods of choice for examining vascular rings.

Double aortic arch is a congenital vascular abnormality in which the connected segments and their branches course between and compress the trachea and esophagus, often resulting in invariable airway compression and gastrointestinal presentations. A 2-month girl with a history of double aortic arch diagnosis in fetal echocardiography was admitted to our hospital with recurrent pneumonia. The double aortic arch was confirmed by computed tomography angiogram. After surgery, the patient was followed for one year of age and had no problem. Our study showed early diagnosis and treatment of a double aortic arch might prevent chronic, irreversible complications.

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 a normal vaginal delivery. Endoscopic assessment of the trachea revealed a pulsatile narrowing at the level of the thoracic trachea, suggestive of an external compression. A contrast-enhanced computed tomography scan of the thorax with three-dimensional reconstruction confirmed the diagnosis of DAA with compression of the trachea and esophagus. Clinicians should strongly consider the possibility of a congenital vascular ring compression should an infant with a normal upper airway present with stridor. A precise diagnosis can be made by radiological examination.

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.
We reviewed charts of infants with double aortic arch who were hospitalized in our department from 2008 to 2014. Age at symptom onset, clinical presentation, diagnostic modality, operative details and post operative outcomes were retrieved.
We identified 7 patients presenting at a median age of 11,8 months (range: 2months-27months) and median weight of 10kg. Respiratory symptoms were present in all cases. Difficulties in feedings were present in 3 cases. Chest radiography, oesophagogram and Computed Tomography (CT) with three-dimentional (3D) reconstructions were performed for all patients. One patient have had laryngo tracheoscopy and 3 patients echocardiography. The dominant branch was the right one in all cases. Associated cardiac anomaly was found in 1case. Operative approach was thoracotomy in 3 cases and thoracoscopic video assisted surgery (VATS) in 4 cases. Median operative time was 132min. Only one patient required conversion. Median hospital stay was 4,1days.
Double artic arch is a rare malformation which can cause persistent non specific respiratory symptoms in infants. The use of 3D-CT scan reconstruction that facilitate diagnosis and the operative approach. Thoracoscopy and thoracotomy are effective procedures even for patients with low weight. The operative time seems similar for both. Thoracoscopy offers less post operative analgesia, shorter hospital stay and good cosmetic results.

Vascular ring is less than 1% of congenital heart disease. Double aortic arch (DAA) is the most common form of it. Its detecting is important because of the effects of pressure on the esophagus and trachea. Case Report: In this study, three children suffering from double aortic arch with symptoms of dysphagia and recurrent aspiration, which in two cases had led to cardiac arrest, were introduced. In all of these studies, computed tomography angiography and chest X-ray were used to diagnose the compression effect of double aortic arch on the esophagus and the surgery provided for treatment of the children. After the surgery, all three patients were monitored in the intensive care unit (ICU) for five days without showing any symptoms. Totally, we found that three computed tomography angiography, as a non invasive, high quality method, would be suitable for the diagnosis of this abnormality.
