Two patients with life-threatening spontaneous hemopneumothorax had developed transpleural, nonbronchial, systemic collaterals from branches of the subclavian artery. It was thought that the collaterals had ruptured due to a collapsed lung and pneumothorax. Transarterial embolization of these arteries was performed, and hemostasis was obtained with no complications. A 37-year-old man underwent embolization of branches of the left internal thoracic artery and the left ascending cervical artery using gelatin sponges and metallic coils. A 33-year-old man underwent artery embolization for extravasation from a branch of the right thyrocervical trunk using n-butyl cyanoacrylate mixed with Lipiodol. Transarterial embolization of a transpleural, nonbronchial, systemic artery provided effective hemostasis in life-threatening spontaneous hemopneumothorax.
