Interventions

Group 1: To screen, if there is a correlation between critical leg ischemia and diameter of the femoral artery, we need an ultrasound examination of the artery before punction. The diameter of the fem

Inclusion criteria

Inclusion criteria: VA-ECMO

Exclusion criteria

Exclusion criteria: No sonography/imaging of the punctured artery prior to the initiation of VA-ECMO to short time in ECMO-therapy

Design outcomes

Primary

Measure	Time frame
Primary outcome will be the scheduled termination of therapy with va-Ecmo and the examination, if there has been critical leg ischemia. Evaluation will be almostly acquired by the documentation written during therapy.	—

Secondary

Measure	Time frame
Predictability of critical leg ischemias with va-ECMO even before punction because of the artery diameters and accordingly prophylactic care with a distal perfusion	—
