Removal of Anti-Angiogenic Proteins in Preeclampsia Before Delivery

The Liposorber LA-15 Device is a dextran sulfate cellulose column, one of several currently approved in Europe and United States for pheresis of lipoproteins in the treatment of familial hypercholesterolemia. Such devices have been in use for over 30 years. Published experience in pregnant women with familial hypercholesterolemia suggests that lipoprotein pheresis can be safely used in pregnancy after appropriate individual benefit/risk assessment for both mother and fetus is considered. The Liposorber LA-15 system selected for this trial has been evaluated for its ability to efficiently and selectively remove sFlt-1 in vitro.
