title: Double lumen aortic arch or persistence of fifth aortic arch?- Report of a case with no associated cardiac defects and literature review.
abstract: Different vascular abnormalities have been reported under the denomination of "persistence of the fifth aortic arch." Detailed studies on experimental embryology raised the discussion about the existence of the fifth aortic arch as an embryological structure, both in humans and mammals. In 1969 the Van Praaghs described the occurrence of double left aortic arch, denominating such anomaly as persistence of the fifth arch. We describe here a female patient showing the presence of an anomalous vessel in parallel with the aortic arch. The finding was occasional, during a preoperative evaluation for cholecystectomy.
