Idiopathic acute massive pulmonary embolism in childhood
MetadataShow full item record
Acute pulmonary embolism (PE) is an uncommon clinical condition in childhood. We hereby present a case report of a 10-year-old child who presented to the emergency department with an acute massive PE. He was transferred by ambulance to our emergency department for dyspnea and perioral cyanosis. His parents denied any previous history of illness or familial disease. Arterial blood gas analysis, electrocardiography, and clinical symptoms and signs collectively raised a suspicion of a probable PE. A contrast-enhanced pulmonary computed tomography scan revealed a massive thrombus in the distal part of the right pulmonary artery with no contrast passage into upper, middle, and lower lobar arteries. Upon ascertaining, the diagnosis of PE, intravenous saline infusion, 3 L/min oxygen through nasal route, and subcutaneous enoxaparin 0.4 cc was administered promptly. As our hospital lacked a pediatric intensive care unit and a further need for administration of pharmacological thrombolysis was anticipated, we transferred the patient to a tertiary care center. PE should always be kept in mind as a differential diagnosis in emergency departments even in pediatric patients.
