“…DDAVP (1-deamino-8-D-arginine vasopressin, desmopressin), a synthetic derivative of vasopressin that promotes the release of VWF multimers from Weibel-Palade bodies in the vascular endothelium, is safe and effective in preventing and treating bleeding in children with VWF levels < 50 iu/dl (Gilly, et al 2002, Khair, et al 2007, Leissinger, et al 2001). In our paediatric population, children are often tested for VWD due to a family history of VWD, personal bleeding history or prolonged partial thromboplastin time, as well as, but not limited to, part of a pre-operative evaluation.…”
