Misaki Ryuge,Masahiko Hara,Takanori Hiroe,Naoki Omachi,Shojiro Minomo,Kazushi Kitaguchi,Mihoko Youmoto,Norihiro Asakura,Yasushi Sakata,Hideo Ishikawa +9 more
TL;DR: Recanalisation was the most common mechanism of recurrent haemoptysis after super-selective bronchial artery coil embolisation and could be managed by 2nd series ssBACE with a procedural success rate of 97.7% without any major complications.
The impact of bronchial artery embolisation on the quality of life of patients with haemoptysis: a prospective observational study
Naoki Omachi,Hideo Ishikawa,Masahiko Hara,Takashi Nishihara,Yu Yamaguchi,Yumiko Yamamoto,Mihoko Youmoto,Tomoaki Hattori,Kazushi Kitaguchi,Shota Yamamoto,Tomoya Kawaguchi,Masahiro Fukuzawa +11 more
TL;DR: In this paper, the effects of bronchial artery embolisation on the HRQoL of patients with haemoptysis were evaluated. But no evidence exists regarding the health-related quality of life (HRQOL) after bronchiaabe embolization.
