Resumo

Anéis vasculares representam 1-2% dos casos das cardiopatias congênitas. Relatamos um caso raro de duplo arco aórtico. Mulher, 60 anos, procurou atendimento na clínica médica apresentando 1 ano de história de disfagia, 6 meses de dispneia e 2 meses de dor torácica esporádica. Raio X de tórax revelou: hiperinsuflação pulmonar difusa, alargamento mediastinal, coração com volume e configurações normais, arco aórtico à direita e alterações degenerativas vertebrais. Tomografia computadorizada do tórax: arco aórtico duplo circundando e comprimindo a traqueia e o esôfago. Arco direito mais calibroso, emergindo dele o tronco braquiocefálico. Do arco esquerdo emergem a artéria carótida comum e a subclávia esquerda. Diagnóstico: anel vascular traqueoesofagiano decorrente do duplo arco aórtico, sendo o arco direito dominante. No presente caso, optou-se por seguimento clínico da paciente, levando-se em conta a intensidade dos sintomas apresentados.

Abstract

Vascular rings represent 1 to 2% of cases of congenital heart disease. We report a rare case of double aortic arch. A 60-year-old woman was admitted to the hospital presenting a one-year history of dysphagia, six months of dyspnea and two months of sporadic chest pain. Radiograph of the chest revealed diffuse pulmonary hyper inflation, widening of the mediastinum, heart of normal size and shape, a right-sized aortic arch, and degenerative changes of the thoracic spine. Computed tomography of the chest showed a double aortic arch encircling and compressing the trachea and the esophagus. The right aortic arch had a larger caliber, with brachiocephalic trunk arising from it. The left common carotid artery and the left subclavian artery arose from the left aortic arch. Diagnosis: tracheoesophageal vascular ring due to double aortic arch, with dominant right arch. In this case, we chose to follow the patient medically, taking into consideration the mildness of the symptoms.
