Treatment algorithm
VWD type unknown with active severe hemorrhage
all types VWD with severe bleeding uncontrolled by desmopressin, antifibrinolytics, and VWF-containing concentrates
all types VWD with severe bleeding or before high-risk bleeding procedures (including where sustained high levels of VWF required for several days): with or without mucosal involvement
all types VWD with minor bleeding or before procedures: involving mucous membranes
type 1, 2A, or 2M VWD: desmopressin responder with moderate mucosal or minor/moderate nonmucosal bleeding or before procedures not involving mucous membranes: nonpregnant
type 1, 2A, or 2M VWD: desmopressin nonresponder with moderate mucosal or minor/moderate nonmucosal bleeding or before procedures not involving mucous membranes: nonpregnant
type 3, 2B, or 2N VWD: all bleeding or procedures except minor mucosal bleeding or before minor procedures involving mucosal surfaces: nonpregnant
all types VWD: pregnant
all types VWD with chronic or recurrent menorrhagia
all types VWD with significant chronic or recurrent bleeding or with treatment-refractory menorrhagia
