title: Embolisation for life-threatening haemoptysis complicated by systemic artery-pulmonary circulation shunts.
abstract: METHODS
  Tertiary referral centre.
  
  
  OBJECTIVE
  To retrospectively observe the characteristics of bronchial angiograms in the setting of systemic artery-pulmonary circulation shunts (SPS), and to evaluate the safety and effectiveness of bronchial artery embolisation (BAE) for these patients with life-threatening haemoptysis.
  
  
  METHODS
  The records of life-threatening haemoptysis patients with SPS who presented to a tertiary referral centre from January 2009 to March 2014 were reviewed.
  
  
  RESULTS
  SPS consisted of bronchial artery-pulmonary artery shunt (AAS) in 30 cases, bronchial artery-pulmonary vein shunt (AVS) in 4 cases, non-bronchial systemic artery-pulmonary circulation shunt (n-BPS) in 7 cases and more than one type of SPS in 4 cases (AAS and AVS in 3 cases, three types of SPS in 1 case). BAE using polyvinyl alcohol (PVA) was successful in 97.8% (44/45) of the patients. Cumulative rates of freedom from recurrence at 1 month, 1 year and 2 years were respectively 97.8%, 93.2% and 85.4%. No major procedure-related complications occurred. No significant differences were found in recurrence rates or cumulative haemoptysis control rates among patients with different types of SPS complications (P = 0.55 and 0.46, respectively).
  
  
  CONCLUSIONS
  BAE with PVA was safe and effective for life-threatening haemoptysis complicated by SPS.
