Critical thrombotic obstruction of transverse aortic arch in a neonate

Abstract

A 3-day-old neonate presented with features suggestive of coarctation of aorta. Echocardiography showed a large organized thrombus in the transverse arch causing obstruction to theaortic arch and carotids with partial recanalization. Patient underwent surgical thromboendarterectomy with arch reconstruction. The evaluation did not reveal any hematological abnormalities and suspected to be due to fetal thromboembolism. Patient improved well, and no neurological deficits were observed during follow-up.
