Clinical Trial Summary
The purpose of this study was to study the efficacy of PPSB-SD and VP-VI in patients, who
received anticoagulant treatment and who had to undergo acute cardiac surgery with a
cardiopulmonary bypass (CPB).
Description:
The value of oral anticoagulants such as coumarin derivatives as a therapy and in the
prophylaxis of thrombosis is universally acknowledged. These medicinal products are used in
the prevention of cerebral infarction, in patients with atrial fibrillation and in the
secondary prevention of myocardial infarction. In case of elected surgery, the effect of
coumarin derivatives can be reversed by a termination of the coumarin treatment and the
administration of vitamin K orally, i.m. or i.v., which will restore the production of the
vitamin K dependent coagulation factors. For patients due to undergo acute surgery, it will
be unfavourable to await endogenous production of vitamin K dependent coagulation factor
production.After CPB surgery, the patients need to be in a controlled coagulated state. Two
products suitable to rapidly increase the concentration of vitamin K dependent coagulation
factors, are fresh frozen plasma (FFP) and prothrombin complex concentrates (PCC). These
products contain factor II, VII, IX and X and help to restore normal levels of the clotting
fraction.Administration of these products prior to CPB surgery will decrease the INR to a
level that is acceptable for surgery. In the Academic Hospital Leuven the standard procedure
in cases of acute and elected CPB surgery is administration of VP-VI, a FFP-product made by
OCTAPHARMA. In this study the standard treatment of 2x 400 ml VP-VI was compared with a
treatment of PPSB Solvent Detergent® (PPSB-SD) according to the prescription regimen of
CAF-DCF. PPSB-SD is a PCC product made by Sanquin Plasma Products (the Netherlands) for
CAF-DCF (Belgium). The regimen as prescribed by CAF-DCF enables to calculate the quantity of
PPSB-SD to administer on the basis of the patient's weight, the initial INR and the target
INR. The expected outcome of the study was that in patients receiving PPSB-SD the target INR
will be reached more frequently and more rapidly compared to patients receiving VP-VI.
