Case report: persistent double dorsal aorta

Introduction: Persistent double dorsal aorta is an extremely rare congenital anomaly, with only 13 cases published so far. The first report was described by Mosquera and Micarelli, in 1975. Objectives: To present in detail the anatomical variation observed in the patient's descending aorta, as well as possible failures in the vasculogenic signaling pathways. Methods: Description of the anatomical variation based on electronic medical records and imaging studies. Prior approval of the current report by the Research Ethics Committee, of the University Center Padre Albino (UNIFIPA) - CAAE: 68416423.0.0000.5430. Results: A 79-year-old patient admitted to hospital care complaining of severe pain in the left lower limb at rest. The patient was asked to be hospitalized to monitor the condition and carry out supportive measures, as well as laboratory and imaging tests. Obtained as an image finding from angio-tomography, the variation consists of the persistence of complete separation into two portions, one ventral and one dorsal, of different calibers, of the dorsal aorta, at the level of the third lumbar vertebra, together with the anomalous origin of the inferior mesenteric. Conclusion: Permanence of the duplicated dorsal aorta is often associated with the presence of birth defects in other organ systems. The visualization of this congenital anomaly occurs mainly by performing imaging tests, however, some reports have evidenced it from autopsy.
