title: Direct complications of the Avalon bicaval dual-lumen cannula in respiratory extracorporeal membrane oxygenation (ECMO): Single-center experience.
abstract: OBJECTIVE
  Cannulation for veno-venous extracorporeal membrane oxygenation (VVECMO) may involve a single site when using a dual-lumen cannula. Benefits include a decrease in blood recirculation, easier patient mobilization, and lower risk of dislodgment. We aimed to review all complications related to the cannula.
  
  
  METHODS
  The study included all adult patients admitted to a single intensive care unit (ICU), between November 2009 and September 2013, requiring VVECMO in whom an Avalon Cannula was inserted. The list of patients, complications, and patient data were retrieved from the local ECMO database and the intensive care Clinical Information System (CIS).
  
  
  RESULTS
  Seventy two patients were cannulated with an Avalon cannula between November 1, 2009 and September 31, 2013. Forty-four patients had no cannula-related complications. A total of 35 complications were recorded in 28 patients, 6 of whom required further intervention.
  
  
  CONCLUSIONS
  Successful cannulation was possible in all patients with the majority of complications graded as minor.
