title: Risk factors for complications after partial splenic embolization for liver cirrhosis.
abstract: BACKGROUND
  Partial splenic embolization (PSE) in patients with cirrhosis can achieve a prolonged increase in blood cell count. However, there is little information on the risk factors for complications after PSE for liver cirrhosis.
  
  
  METHODS
  Seventy patients (41 men and 29 women) with cirrhosis-induced hypersplenism underwent PSE. Based on the Child-Pugh classification, 30, 35 and five patients had class A, B and C disease respectively. Risk factors for complications after PSE were examined retrospectively by logistic regression analysis.
  
  
  RESULTS
  The mean splenic infarction rate was 77.1 per cent. Twelve patients (17 per cent) had complications following PSE. In univariable analysis, Child-Pugh class C, total bilirubin level of 1.4 mg/dl or more, serum albumin level of 2.8 g/dl or less and infarcted splenic volume of 540 ml or more were significantly associated with complications after PSE. In multivariable analysis, Child-Pugh class C (P = 0.012) and infarcted splenic volume of 540 ml or more (P = 0.031) were identified as risk factors, with an odds ratio of 22.92 and 5.01 respectively.
  
  
  CONCLUSIONS
  Child-Pugh class C and a large splenic infarction volume are risk factors for complications after PSE for liver cirrhosis.
