A pathological study following bronchial artery embolization for haemoptysis in cystic fibrosis

Abstract

A detailed post-mortem study is reported on an adult with cystic fibrosis who died in respiratory failure three weeks after selective bronchial artery embolization with gelatin sponge to treat severe haemoptysis. Bronchial arteriography during the procedure showed complete occlusion of the vessel supplying the righ upper lobe and following this the bleeding stopped. However, post-mortem angiography of the same vessel demonstrated disappearance of much of the injected material with contrast bypassing the remaining gelatin to fill the peripheral bronchial arterial bed. This report therefore adds pathological evidence to previous clinical reports which have suggested that this procedure may not produce permanent occlusion of the embolised bronchial artery.
