Abstract

Infarction of the lung usually results from pulmonary arterial obstruction. Pulmonary infarcts often become infected from bronchial contamination and may become lung abscesses, empyema, or bronchopleural fistula causing sepsis. Diagnosis is important for intensive therapy, since infection is prone to spread. Resection of the infarcted lung should be considered early in an attempt to control infection. A sixty-seven-year-old man was hospitalized with dyspnea. A computed tomographic scan of the chest showed left lower lobe infiltration and mild pleural effusion with pleural thickening. There was a thrombus in the left pulmonary artery leading from the lower lobe to the upper lobe artery. At operation, the left lower lobe was found to have complete hemorrhagic infarction. The left lower lobectomy was performed. The remaining thrombus was removed after the left main pulmonary arteriotomy. He has been followed up for 15 months and has done well with no recurrence of thrombus and infarction of the lung.

폐경색은 폐동맥의 폐색으로 인해 발생하며 기관지내 세균오염에 의해 폐감염이 흔하게 속발하며 이는 폐농양, 농흉 그리고 기관지 흉막루 등을 일으켜 결국 패혈증에 이르게 할 수 있다. 이러한 이유로 조기 진단이 중요하며 감염 조절을 위해 폐절제 등을 조기에 고려해야 한다. 67세 남자가 호흡곤란을 주소로 응급실에 내원하였다. 흉부 전산화 단층 촬영에서 좌하엽에 침윤성 병변과 소량의 흉수 그리고 늑막 비후가 관찰되었다. 폐색전은 하엽 폐동맥에서 상엽 폐동맥까지 자라나 있었다. 출혈성 경색이 완연한 좌하엽은 절제되었고 좌주폐동맥을 열어 나머지 폐색전을 제거하였다. 수술 후 15개월간 추적 관찰하고 있으며 폐색전이나 폐경색의 재발은 보이지 않았다.
