Bronchial artery embolization to control hemoptysis in patients with Mycobacterium avium complex

Mechanisms of recurrent haemoptysis after super-selective bronchial artery coil embolisation: a single-centre retrospective observational study

“…In light of this, we speculate that the most common mechanism of recurrent haemoptysis, namely recanalisation, may occur more frequently during ssBACE compared to BAE performed with PVA or NBCA. However, the mechanisms of recurrent haemoptysis following BAE using PVA or NBCA have yet to be investigated [10][11][12][13][14][15][16][17]. We also demonstrated that the development of new HRAs was the second most common cause of recurrent haemoptysis in this study, in which 108 (93.9%) were new development of HRA.…”

“…Recanalisation and the development of new HRAs caused more that 80% of the HRAs at the 2nd series ssBACE. In contrast to PVA and NBCA, which serve as bloodstreamdependent linear liquid embolisation materials, ssBACE provides patients with controlled pinpoint embolisation of target HRAs [10][11][12][13][14][15][16][17]. In light of this, we speculate that the most common mechanism of recurrent haemoptysis, namely recanalisation, may occur more frequently during ssBACE compared to BAE performed with PVA or NBCA.…”

“…As a result of the significant negative impact of massive haemoptysis on a patient's quality of life and risk of mortality, an interventional radiological approach known as bronchial artery embolisation (BAE) has been introduced and evaluated extensively [7][8][9][10][11][12][13][14]. In addition, interest has recently started to shift to long-term haemoptysis-free survival rather than shortterm haemostatic rate, since short-term haemostasis can be achieved in the majority of cases owing to advancements in interventional devices and medical knowledge [9][10][11][12][13][14][15][16][17]. For example, BAE performed using polyvinyl alcohol (PVA) or N-butyl-2-cyanoacrylate (NBCA), or using a metallic coil, has been shown to produce much more favourable long-term outcomes compared to BAE performed using a gelatin sponge [14,16].…”

“…The largest observational studies to date have shown that the estimated 1-year haemoptysis-free survival rates for BAE performed using PVA, NBCA and a metallic coil are 77%, 88% and 87%, respectively [14,16]. However, little evidence is available on the mechanisms of recurrent haemoptysis after BAE using metallic coil [11][12][13][14][15][16][17]. The aim of the present study was to evaluate the mechanisms of recurrent haemoptysis using both enhanced-computed tomography (e-CT) and cineangiography after super-selective bronchial artery coil embolisation (ssBACE) by reviewing 299 haemoptysis-related arteries (HRAs) from 57 consecutive patients who underwent 2nd series ssBACE for the management of recurrent haemoptysis.…”

Erratic coil migration in the bronchus after bronchial artery embolization

“…Various embolic agents are used in BAE, including polyvinyl alcohol, n‐butyl‐2‐cyanoacrylate (NBCA) , gelatine sponges, and metallic coils. BAE using coils (super‐selective bronchial artery coil embolization (ssBACE)) is a relatively new method and is regarded safe and effective . We reported 1‐year haemoptysis‐free rate, 2‐year haemoptysis‐free rate, and major complications as 90.4%, 85.9%, and 1.6%, respectively, in our long‐term follow‐up of 489 ssBACE cases .…”
