Abstract
Coarctation of a right aortic arch is rare congenital anomaly. We report a rare case
of a 24-year-old female with coarctation of the right aortic arch with aberrant left
subclavian artery between the right common carotid and right subclavian arteries.
The coarctation progressed into complete obstruction as the interruption of the aorta
in adulthood. To prevent cerebral complications and progression to heart failure,
surgical procedure was selected. Extraanatomical bypass grafting between the ascending
and descending aorta was successfully performed using cardiopulmonary bypass. Some
patients diagnosed with interruption of the aortic arch in adulthood might be displaying
progression of undiagnosed coarctation, as our in case. Three-dimensional computed
tomography was useful to detect the obstructive lesion and to determine the surgical
approach and methods.
Key words
Coarctation - right aortic arch - interruption - adult surgery
