Congenital anomalies of the aorta are caused by an embryogenetic disorder and have a low incidence in general population (2/1.000 live births). They can be classified in: obstructions of the left ventricular outflow (subvalvular stenosis, valvular malformation, supravalvular stenosis like as in Williams syndrome), vascular rings (duble aortic arch, rightsided aortic arch), aortic coarctation, interrupted aortic arch and patent ductus arteriosus (see fig.from 1 to 4).
Congenital anomalies of the aorta are often symptomatic, especially when associated with other cardio-vascular disorders, and difficult to study in new born or pediatric patients with hemodynamic and respiratory instability.
Last generation CT (in our cases 320 slides CT) represente nowadays a non invasive technique that allows rapid imaging acquisitions, decreasing the sedation time, with a relatively good evaluation of vascular anatomy thanks to post-processing reconstructions of the angioghrapic images. The disadvantage of x-ray exposure can be reduced using low dose CT protocols and with modulation of radiation beam (table 1).
A review of congenital aortic anomalies;
Advantages of last generation CT in pediatric patients: rapid acquisition, good evaluation of vascular anatomy by post-processing reconstructions; modulations of radiation dose.
