Abstract

A pulmonary thromboembolism (PTE), which is a sudden blockage in a pulmonary artery, usually due to a blood clot, is rare in children. The clinical presentation is often subtle or masked by the underlying clinical condition and the condition must be suspected during clinical testing. Although the choice of treatment depends on the clinical presentation, anticoagulation is the mainstay of therapy for children with PTE. We report the case of a healthy 1-month-old boy who presented with hemoptysis without hemodynamic instability. He was diagnosed based on chest computed tomography with angiography and 99mTc macroaggregated albumin lung perfusion scintigraphy and treated with low-molecular-weight heparin.

폐혈전색전증은 혈전에 의해서 폐동맥이 갑자기 막혀 폐동맥 혈류의 장애를 초래하는 질환으로 1861 Steveson에 의해 처음 보고되었다. 소아에서는 매우 드문 질환이나 최근에는 소아 치료 기술의 향상으로 장기 입원 환자가 늘고 중심정맥도관 삽입 기회가 늘어남에 따라 그 발병률이 증가되었을 것으로 추정된다. 임상증상은 비특이적이며, 폐혈류 장애정도와 질환의 급성도에 의해 중증도가 결정되어 임상증상만으로 이 질환을 진단하기는 어렵다. 먼저 위험인자가 있는 환아에서 질환을 의심하고 이에 따른 영상검사를 시행하여 확진되거나 의심되면 치료를 시작하는 것이 중요하다. 아직 소아에서의 치료에 대해서 연구가 부족한 상태로 성인을 대상으로 시행한 연구에서 효과적이라고 알려진 치료법을 소아에 적용하고 있는 실정이다. 국내에서는 건강한 영아에서 발생한 폐혈전 색전증의 진단이나 치료에 대하여 보고된 바가 없어 저자들은 객혈을 주소로 내원한 위험요인이 없었던 건강한 환아에서 폐혈전색전증을 진단하고 저분자량 헤파린 치료를 통해 회복된 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.
