ABSTRACT
Thromboembolic disease in children and the use of anticoagulant drugs for its prevention and treatment have increased dramatically over recent years. There are many reasons for this increase. First, improved survival of children, who previously would have died of primary illness, has created a population at risk for thromboembolic disease. In addition, increased use of central venous, and arterial access, devices has dramatically increased the frequency of iatrogenic thromboembolic disease. Finally, improved imaging techniques have enabled more accurate diagnosis of thromboembolic diseases in specific circumstances.
