Thrombosis of the abdominal aorta in a newborn: Case report and review of literature

The case of a newborn infant who presented thrombosis in the abdominal portion of the aorta, which resulted in the complete occlusion is reported. Diagnosis was made using Doppler echocardiography. The initial therapeutic approach was clinical support, but as the thrombi started to increase in size (secondary thrombosis) and evolved to the infrarenal terminal aorta, anticoagulation with heparin was indicated. The total disappearance of both the secondary thrombosis and the embolus was evidenced by a subsequent echocardiography after the anticoagulation therapy.
