Management of neonatal and infant aortic thrombosis: A single-center case series

Abstract

Neonatal and infant aortic thrombosis is a rare albeit life-threatening thrombotic event, particularly seen in premature infants with an arterial catheter in place. We describe our institutional experience and approach to the management of 11 infants with occlusive or nearly occlusive aortic thrombosis. We observed at least partial thrombus resolution in all patients. Complications related to our management included minor bleeding in two children receiving thrombolytic therapy, and two major bleeding events in children receiving anticoagulation alone. Our experience adds to the growing body of evidence that thrombolysis and thrombectomy should be considered in managing neonatal/infant aortic thrombosis.
