Extracorporeal membrane oxygenation in lung transplantation: Indications, techniques and results

Table 1 Different ECMO configurations in lung transplantation

ECMO configuration	Cannulation	Support provided	Patient condition	Utilizazion in LTx
VV	Peripheral (double lumen cannula in the SVC via the jugular or subclavian vein or a single lumen cannula in the femoral vein or jugular and femoral veins)	Only respiratory	Hypoxemia	Bridge to transplantation; post-operative period
VA	Peripheral (femoral vessels; jugular/subclavian vein and subclavian artery)	Respiratory + circulatory	Hypoxemia and cardiac failure	Bridge to transplantation; intra-operative; post-operative period
	Central (from right atrium to aorta)
VVA	Same as VV ECMO + an additional cannula in the subclavian artery	Respiratory + circulatory	Severe right heart dysfunction with hypoxemia	Bridge to transplantation; intra-operative; post-operative period

VV: Veno-venous; VA: Veno-arterial; VVA: Veno-venous arterial; ECMO: Extracorporeal membrane oxygenation, LTx: Lung transplantation, SVC: Superior vena cava.
