Abstract: The incidence of pulmonary embolism in children is increasing. Different from adults，there is no obvious specificity in clinical manifestations of pulmonary embolism. Hemodynamic instability is rare. It is likely to be misdiagnosed or to fail to diagnose and the mortality is high. Most of the experience in treatment comes from that for adults. Due to the characteristics of children，the experience of treatment is insufficient. Now in order to improve clinicians’ understanding of the disease and reduce mortality，we review the incidence，risk factors，clinical manifestations，diagnosis，treatment，prevention and prognosis of pulmonary embolism in children in order to make early diagnosis and treatment.

Key words: child, pulmonary embolism, D-dimer, CT-PA
