Clinical application of feeding-artery embolization in treating massive hemoptysis / 介入放射学杂志

ABSTRACT

Objective To discuss the clinical application of feeding-artery embolization in treating massive hemoptysis.Methods The feeding-artery angiography was performed in 72 patients with massive hemoptysis.Based on the angiographic findings polyvinyl alcohol(PVA)or spring coil were selected as the embolization materials.The therapeutic results were retrospectively analyzed. Results Hemoptysis was completely controned almost immediately after the embolization procedure in 46 cases,while it was obviously alleviated in 13 cases.In 11 cases the hemoptysis disappeared completely after 2-4 times of embolization treatment,and in 2 cases surgery had to be employed.Conclusion Embolization of feeding-artery with PVA particles or spring coils is an effective and safe treatment for massive hemoptysis.The key point for decreasing reoccurrence is to occlude all feeding.arteries as far as possible.
