title: Risk factors for and causes and treatment of recurrence of inferior vena cava type of Budd-Chiari syndrome after stenting in China: A retrospective analysis of a large cohort.
abstract: OBJECTIVE
  To explore the risk factors for recurrence of inferior vena cava (IVC)-type Budd-Chiari syndrome (BCS) after stenting and evaluate the feasibility and primary outcomes of endovascular therapies for recurrent BCS.
  
  
  METHODS
  A retrospective analysis of 219 patients was performed to identify risk factors for recurrence. The images of the recurrent patients during follow-up duration and interventional surgery were also reviewed to find the possible reasons of recurrence. The outcome of endovascular therapies for recurrent BCS was evaluated by Kaplan-Meier analysis.
  
  
  RESULTS
  Among the 219 patients, 172 patients with primary IVC-type BCS underwent stenting and 28 patients experienced recurrence. Multivariate analysis identified age, Child-Pugh score, MELD and total bilirubin as independent recurrent indicators. Possible causes of recurrence include thrombosis in the stent, re-obstruction in or above the stent, and stent-related hepatic vein obstruction. Twenty-five patients with recurrent BCS underwent endovascular therapies with a few complications and achieved a high level of short- and mid-term patency.
  
  
  CONCLUSIONS
  Age, total bilirubin and severity of liver function are the main risk factors for BCS recurrence. These risks might contribute to thrombosis or subsequent fibrous obstruction. Endovascular therapies are effective and safe management options that yield positive outcomes for recurrent BCS.
  
  
  CONCLUSIONS
  • Risk factors for recurrent Budd-Chiari syndrome were identified by multivariate analysis. • Causes of recurrent Budd-Chiari syndrome were investigated by assessing radiological images. • There is a correlation between risk factors and causes of recurrence. • Endovascular therapies for recurrent Budd-Chiari syndrome are effective and safe.
