[Neonatal thrombosis of the aortic arch]

Abstract

The authors report a case of aortic arch thrombosis in a neonate probably related to perinatal placental emboli. However the finding of a fibroblastic endarteritis raised the possibility of a primitive lesion of the aortic wall. The evolution was complicated by cerebral ischemia. A surgical thrombectomy was performed. The outcome was favourable with persistence of a moderate right motor deficiency at 9 months. The authors advise the addition of an enlargement patch and the use of anticoagulation therapy in case of intimal lesion or very adherent thrombus.
