Aortic thrombosis in a newborn

: The aortic thrombosis is not frequent during the neonatal period. The canalization of umbilical artery is the main risk factor. There are several options for the treatment, such as thrombolysis, thrombectomy and the anticoagulation, which are used in terms of the thrombosis localization and the symptoms that are observed. We present the case of a newborn who consulted for weak femoral pulses, coldness and poor perfusion of lower limbs. The aorta restriction was ruled out using the echocardiography; Doppler abdominal ecography showed aortic thrombosis at an underrenal level. There was not a previous umbilical catheterism.
