A standard definition of post-partum hemorrhage (PPH) considers the threshold of >500 mL blood loss for vaginal delivery and of >1,000 mL for caesarean section 13. Rates of PPH in Western Countries based on hospital discharge may range from 3 to 6%, while cases needing blood transfusion are as low as 1 % 10.

May 20, 2019 · 1 INTRODUCTION. Von Willebrand disease (VWD), the most frequent autosomal inherited bleeding disorder, is caused by quantitative or qualitative defects of von Willebrand factor (VWF), an adhesive protein that binds platelets to exposed sub-endothelium and carries factor VIII (FVIII) in circulation. 1, 2 As a consequence, in addition to the defect of VWF, also FVIII, the protein deficient in ...

Jun 7, 2022 · Von Willebrand disease (VWD), first described by Dr. Erik von Willebrand, is the most common autosomal inherited bleeding disorder. It is caused by deficiency or dysfunction of von Willebrand factor (VWF), a plasma protein that mediates the initial adhesion of platelets at sites of vascular injury, and binds and stabilizes blood clotting factor ...
Oct 26, 2021 · The usual cause of von Willebrand disease is an inherited abnormal gene that controls von Willebrand factor — a protein that plays a key role in blood clotting. When you have low levels of this protein or it doesn't work as it should, small blood cells called platelets cannot stick together properly nor attach themselves normally to the blood ...
Jan 1, 2022 · The studies did not describe outcomes based on VWF levels, but rather described outcomes of women with VWF levels >0.50 IU/mL (without specifying which proportion of women had levels >1.50 IU/mL). Therefore, there was very-low-certainty evidence about the comparative effects of increasing the VWF levels to 0.50 to 1.50 IU/mL vs >1.50 IU/mL.
Apr 26, 2010 · von Willebrand disease is caused by either a quantitative or qualitative defect in von Willebrand factor (VWF). Patients may have extensive mucosal bleeding (because of platelet dysfunction) and prolonged bleeding after surgery (because of factor VIII deficiency). Up to 6 different subtypes of the disease have been described, and diagnosis is based on clinical suspicion and laboratory ...
