title: Pathologic evaluation of damage to bronchial artery, bronchial wall, and pulmonary parenchyma after bronchial artery embolization with N-butyl cyanoacrylate for massive hemoptysis.
abstract: Histologic evidence of safety after bronchial arterial embolization (BAE) with N-butyl cyanoacrylate (NBCA) should be assured. The present report describes a 78-year-old man with massive hemoptysis from lung cancer who underwent surgical lobectomy 23 days after hemostasis had been achieved via BAE with NBCA. Pathologic examination revealed that NBCA filled the lumen of bronchial branch arteries 143-1,094 μm in diameter from the lobar bronchus to subsegmental bronchus but was not seen in the lumen of the pulmonary artery or pulmonary vein. NBCA induced occlusion of bronchial branch arteries but no necrosis of the bronchial wall or pulmonary parenchyma.
