A Case of Isolated Interruption of the Aortic Arch without Any Complications of Other Cardiovascular Malformations / 日本心臓血管外科学会雑誌

ABSTRACT

A 7-year-old boy suffered from isolated interruption of the aortic arch without any other complications or cardiovascular malformations. Cardiac murmur, which had been apparent since one month of age, had been left untreated because of the absence of any symptoms of heart failure. Isolated interruption of the aortic arch was noted during a routine physical examination at school and the patient was referred to our hospital for a complete medical evaluation. Blood-pressure difference was recognized not only between the right side and the left side of the upper extremities but also between the upper and lower extremities. On the basis of the results obtained via magnetic resonance angiography (MRA) and aortography, a definitive diagnosis of isolated interruption of the aortic arch was made. Reconstruction of the aortic arch by synthetic implant was indicated. The blood-pressure difference disappeared and the postoperative course was satisfactory.
