Abstract

Aortic coarctation is characterized by a segmental narrowing of the aortic lumen, usually diagnosed and treated in the neonatal period or early childhood, but can remain undiagnosed until adulthood. It manifests as a broad spectrum of signs and symptoms, ranging from mild to severe, of which arterial hypertension is one of the most common. In this article, the authors describe the clinical case of a 9-year-old child under investigation in the Pediatric Department for secondary causes of arterial hypertension. A renal Doppler ultrasound study revealed the presence of bilateral parvus et tardus waveform morphology in renal and intrarenal arteries and the proximal abdominal aorta. These findings were suspicious for diagnosing aortic coarctation, which thoracic CTangio confirmed.
