Abstract

Flow-volume loop is known to be useful in the diagnosis of upper airway obstruction. In cases of tracheal obstruction, characteristic features such as fixed or variable upper airway obstruction patterns give clue to the diagnosis. But the flow-volume loop of unilateral mainstem bronchial stenosis is not known well. There is controversy in patterns of flow-volume loop in unilateral mainstem bronchial stenosis (restrictive pattern or biphasic pattern). We report a case of biphasic flow-volume loop in left mainstem bronchial stenosis(4-5 mm in diameter) as a sequela of endobronchial tuberculosis, which recovered normal flow-volume loop after metallic stent insertion and 2 months later showed reappearance of biphasic pattern because of restenosis of left mainstem bronchus due to growth of granulation tissue at the stent site.

저자들은 기관지결핵의 후유증으로 좌주기관지 협착이 있었던 환자가 이상성 기류유량곡선을 보인 후 금속스텐트 삽입후 교정되었다가 스텐트 삽입 2개월 후부터 육아종형성에 따른 좌주기관지의 재협착이 나타나 다시 기류유량곡선상 이상성 기류유량곡선을 보인 증례를 경험하였기에 보고하는 바이다.
