[Pulmonary embolism in the child: diagnostic and therapeutic particularities]. / Embolie pulmonaire de l'enfant: particularités diagnostiques et thérapeutiques.

BACKGROUND: Pulmonary embolism in children is an overlooked pathology. Yet the first description dates back to the end of the 19th century and this specific pathology is not seldom observed. The main risk factors are trauma, surgery, and foreign bodies. DIAGNOSIS: Thrombophilia can be diagnosed when a thromboembolic event occurs. The initial thrombosis may be found anywhere in the venous network. Venous sonography usually gives the diagnosis. Pulmonary embolism usually has a poor clinical expression. An unexplained situation can be the first manifestation. Echocardiography guides diagnosis confirmed by ventilation-perfusion scintigraphy. TREATMENT: Prophylaxis is achieved with small doses of heparin. Treatment is based on the use of hypocoagulant doses of heparin, potentially after systemic thrombolysis and followed by oral anticoagulation.
