ABSTRACT
Double aortic arch is a rare anomaly of the aortic arch. It is due to the absence of involution of the caudal dorsal aorta. The disease usually begins to show itself in very early clinical signs, already detectable in the neonatal period. Angiography is of great interest to its diagnosis as well as to the choice of the therapeutic approach. Only surgical treatment allows to eliminate tracheoesophageal compression. Surgical mortality rate is low thanks to the progress of postoperative resuscitation. We here report two cases of double aortic arch in order to highlight the contribution of imaging in the difficult diagnosis of this anomaly.

Neonatal thrombopenia is the most common hemostatic abnormality in newborns. It is defined as a platelet count below 150.000/mm3. 40% of newborns to mothers with a history of autoimmune thrombopenia are at risk of developing neonatal thrombopenia while 10-15% of them are at risk of developing severe thrombopenia. We here report the case of a 20 days old newborn to mother splenectomized for idiopathic thrombopenic purpura in order to highlight the relationship between the severity of maternal disease and the severity of the neonatal thrombopenia and thereby to avoid the risk of intracranial hemorrhage resulting in death or neurological sequelae.
