[Double aortic arch with dominant left arch: case report].

A vascular ring is defined as an anomaly of the great arteries (aortic arch and its branches) that compresses the trachea or esophagus. Double aortic arch is the most common vascular ring. Double aortic arch is very rare and typically becomes symptomatic in infancy or early childhood. We present a 7-year-old girl admitted to our clinic for evaluation of recurrent respiratory infection with dysphagia. Double aortic arch was suspected from echocardiography and diagnosed with cardiac computed tomography. Left aortic arcus was larger than the right at computed tomography and cardiac catheterisation. After surgery the symptoms improved strikingly. We conclude that vascular ring should be considered in the patients presenting with recurrent pulmonary infections and dysphagia. Early diagnosis and treatment may prevent chronic, irreversible complications.
