title: Incidence and risk factors of contrast-induced nephropathy after bronchial arteriography or bronchial artery embolization.
abstract: BACKGROUND
  In uncontrolled hemoptysis patient, bronchial arteriography and bronchial artery embolization (BAE) is a important procedure in diagnosis and treatment. The aim of this study is to assess the incidence of contrast-induced nephropathy and the risk factors of contrast-induced nephropathy (CIN) after bronchial arteriography and BAE.
  
  
  METHODS
  We retrospectively reviewed the medical records of the patients who underwent bronchial arteriography and BAE in two university hospitals from January 2003 to December 2011. CIN was defined as rise of serum creatinine more than 25% of baseline value or 0.5 mg/dL at between 48 hours and 96 hours after bronchial arteriography and BAE. We excluded patients who already had severe renal insufficiency (serum creatinine≥4.0) or had been receiving dialysis.
  
  
  RESULTS
  Of the total 100 screened patients, 88 patients met the enrollment criteria. CIN developed in 7 patients (8.0%). The mean duration between the exposure and development of CIN was 2.35±0.81 days. By using multivariate analysis, serum albumin level was found to be significantly associated with the development of CIN (p=0.0219).
  
  
  CONCLUSIONS
  These findings suggest that the incidence of CIN was higher than expected and patients with hypoalbuminemia should be monitored more carefully to prevent the development of CIN after bronchial arteriography and BAE.
