[Case of primary racemose hemangioma of a bronchial artery with life-threatening hemoptysis].

A 22-year-old woman was admitted to our hospital because of hemoptysis and respiratory insufficiency. The chest roentgenogram and the chest computed tomogram showed infiltrative shadows in the bilateral lower lobes and mediastinal emphysema. On the second day of hospitalization, we performed double lumen endotracheal tube intubations for the repeated life-threatening hemoptysis. Bronchoscope examination revealed normal bronchus with fibrin formation. Bronchial autobiography (BAG) showed a convoluted and enlarged right bronchial artery and bronchial-pulmonary artery shunt. We diagnosed primary racemose hemangioma of a bronchial artery and performed bronchial artery embolism (BAE) of the right upper bronchial artery using coil. There was no reccurence of hemoptysis after BAE procedure. BAE with coil seems to be effective for life-threatening hemoptysis due to racemose hemangioma.
