Abstract :
The incidence of thromboembolic events in the pediatric age group is higher in neonates (1).
In a German study the incidence of thromboembolc
events in the neonatal period was 5.1 per 100000 births (2)
and 2.4 per 1000 NICU admissions with 45% to 55% of these
events occurring in preterm infants (3). Risk factors for
thromboembolic events are infection, polycythemia, gestational diabetes mellitus of mothers, perinatal asphyxia
and inherited thrombophilia such as factor 5 Leiden and
deficiency of protein C and S, dehydration and shock,
congenital heart disease, umbilical venous and arterial
catheters (1, 4). Thromboembolic events in the neonatal
period often require urgent intervention to restore perfusion and to prevent morbidity and even mortality. The
most common clinical findings are irritability, absent peripheral pulses, pallor or duskiness of extremities, coldness of the lower extremities and difference between the
upper and lower extremities’ tensions. Diagnosis of arterial thrombosis is confirmed by ultrasonography. Therapeutic options include anticoagulation, fibrinolytic therapy, surgical thrombectomy or combination of these therapies according to location of thrombosis and clinical finding
