Anillos vascu lares completos

The complete vascular rings, embryological anomalies of theaortic arch and great vessels, are frequently incidental findings, although patients with significant anomalies can present with upper airway and oesophagus compression, resulting in non-cardiac morbidity. The diagnostic needs high clinical suspicion. We describe six cases, with a mean age of two and a half months at diagnosis. The objective of our review is to describe the type of complete vascular ring (double aortic arch, right circumflex aortic arch and right aortic arch with aberrant left subclavian artery and left ligamentum arteriosus), the most common symptoms (respiratory symptoms including constant high-pitched, aggravated crying) and invasive and non-invasive diagnostic procedures (esophagograms, CT, MRI).
