Acute aortic dissection in children and adolescents: diagnostic and after-event follow-up obligation to the patient and family.

Acute aortic dissection in childhood and adolescence is a rare but life-threatening condition with many known risk factors, most of which are heritable. The importance of determining the presence of any predisposing disorders is stressed, since all close relatives can then be screened for any such inherited trait that would make them at risk for a similar catastrophic event. Even with no obvious predisposing disorder, it may still be prudent to evaluate close kin for the presence of aortic root dilatation, since some genetic disorders have no manifestation other than acute aortic dissection secondary to aortic medial pathology. Close monitoring for at-risk family members, including the index patient, may need to be a life-long process.
