Management of neonatal aortic arch thrombosis with low-molecular weight heparin: a case series.

Aortic arch thrombosis (AAT) is a potentially life threatening condition in neonates. We report 3 neonates with AAT and complete occlusion of a unilateral internal carotid artery with multiple cerebral infarcts. Multidisciplinary input led to deferral of thrombolytic therapy and surgical thrombectomy owing to the potential risk of hemorrhage within the infarcts.
