Evaluation of bronchial artery embolization for hemoptysis *
Bronchial artery embolization (BAE) was performed for 12 cases of hemoptysis due to nonneoplastic lung diseases between February 1994 and February 1998. A gelfoam fragment and coils were used as embolic material. Immediate control of hemoptysis was achieved in eleven patients (92% ).Recurrent hemoptysis occurred in 3 of the 12 patients. Cases of rebleeding were evaluated. The cause of recurrence in two of the three cases was recanalization of a bronchial artery. In the remaining case, other systemic vessels may have contributed to the blood supply of the lesions. Such non-bronchial collaterals are well recognized and may arise from intercostal arteries and branches of the subclavian artery. It is important to search for non-bronchial collateral arteries and an angiogram should be obtained before BAE. (Accepted on August 27. 1998) Kawasaki Igakkaishi 24(2) : 77-82. 1998
