Is lower limb venous drainage during peripheral extracorporeal membrane oxygenation necessary

: Extracorporeal membrane oxygenation (ECMO) is becoming a gold standard in acute heart failure, not responsive to inotrops and intra-aortic balloon contrapulsation. This diffusion is due to the possibility to implant it through peripheral cannulation and to perform long-time assistance. Nevertheless, this technique implies some problems concerning inferior limb perfusion. It is widely accepted that arterial distal cannulation and perfusion of the limb is mandatory, especially for long periods of assistance; but the necessity to implant a distal venous drainage is still discussed. We would like to present our experience on peripheral ECMO where we could avoid venous distal drainage uneventfully.
