To retrospectively assess the effectiveness and safety of customized hemostatic protocols using a plasmaderived, von Willebrand Factor (VWF)-containing Factor VIII concentrate (pdVWF/FVIII) in von Willebrand disease (VWD) patients undergoing dental invasive procedures. Methods: Protocol for each patient was drawn up by the Blood Unit based on the VWD type, disease severity, and type of treatment. pdFVIII/VWF infusions and doses were registered at 30-60 min before intervention (t0) and at 12-24-36-48-72 h after intervention (t12-t72) and up to day 7. Any peri-or postoperative bleeding, complication or adverse event was registered. Results: Forty-five dental procedures were performed on 20 VWD patients (six type-1, two type-2a, six type-2b, six type-3). Most pdFVIII/VWF infusions at t0 were 60 IU/kg (n ¼ 7) and 50 IU/kg (n ¼ 9). Subsequent infusions were mostly 30-50 IU/kg. No bleeding complications or adverse events were reported.
Conclusion:This study supports the safety and efficacy of pdFVIII/VWF to prevent peri-and postoperative bleeding after invasive oral procedures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
