Atresia of abdominal aorta in neonate with recanalization and development of normal aortic architecture: case report and review of literature.

This is a case report reviewing the presentation and clinical course of a patient diagnosed with abdominal aortic atresia at the level caudal to the superior mesenteric artery. Patients with abdominal aortic atresia need to be evaluated for associated underlying syndromes or diseases. Although the prognosis for this disease is not well documented in the literature, it is important to follow patients to assess for hypertension, renal insufficiency, or claudication. However, we present a rare case in which follow-up imaging revealed normal abdominal aorta vasculature and branching vessels with no collateralization present.
