    • Abstract:
      Objective: Description of a case report.
      Patients: The case of a 55-years-old man with a previous history of hypertension, treated for several years with many antihypertensive drugs without improvement is described.
      Results: The patient was affected with a unknown coarctation of the aorta. This disease, in fact, is an important cause of secondary hypertension. Adult patients, if asymptomatic, are most often diagnosed because of hypertension or murmur on a routine examination. This congenital disease can be demonstrated on suprasternal notch two-dimensional echocardiographic views along with increased Doppler flow velocity across the coarctation site. TC scan and aortography confirm the degree and nature of the aortic narrowing.
      Conclusions: In the case reported color Doppler ultrasonography demonstrated two peculiar aspects of the coarctation of the aorta: 1) detection of a stenotic flow in the abdominal aorta, abdominal and lower extremities arteries; 2) marked renal vasodilatation secondary to compensatory mechanisms that intervene in the renal flow reduction; this finding is detectable in the presence of bilateral stenosis of renal arteries as well as in the hypertensive forms of coarctation of the aorta.
