The Swan-Ganz catheter is a reliable method used to monitor hemodynamics in intensive care units. Pump-controlled retrograde trial off is a new weaning test for veno-arterial extracorporeal membrane oxygenation in recent years. The objective of this report is to describe a case in which pulmonary artery flotation catheter hemodynamic monitoring in combination with pump-controlled retrograde trial off was sufficient for veno-arterial extracorporeal membrane oxygenation weaning. ⋯ The combination of pulmonary artery flotation catheter hemodynamic monitoring and pump-controlled retrograde trial off can increase the possibility of veno-arterial extracorporeal membrane oxygenation successful decannulation.

In cases of severe cardiopulmonary deterioration, quick establishment of venoarterial extracorporeal membrane oxygenation (ECMO) represents a support modality. After successful arterial peripheral cannulation, a certain grade of peripheral limb malperfusion is a fairly common phenomenon. Detection of peripheral malperfusion is vital, since it can result in compartment syndrome or even loss of the affected limb. ⋯ Comparatively, the 17-Fr-sized cannula performs on a scale of 140 ± 20 to 390 ± 60 mL distal perfusion cannula blood flow at 1.5-5.0 L min-1 ECMO blood flow, respectively. The quantitative assessment of the distal perfusion cannula blood flow has revealed that distal perfusion cannula blood flow can measure up to 10% of the ECMO blood flow. Furthermore, it has been also well demonstrated that the novel distal perfusion cannula is sufficient to compensate peripheral limb ischaemia.
