Abstract |
von Willebrand disease is a bleeding disorder characterized by a complex hemostatic defect. These
abnormalities arise from quantitative and/or qualitative abnormalities of von Willebrand factor
which circulates in plasma complexed with the factor VID procoagulant protein.
We have experienced three cases of type I von Willebrand disease in two children and their
mother. They had prolonged bleeding time and partial thromboplastin time, mildly decreased factor
VIII coagulant activity, marked reduction of ristocetin induced platelet aggregation, low level of von
Willebrand factor antigen and ristocetin cofactor activity, but normal multimeric structure of von
Willebrand factor.
Their bleeding time was corrected after intranasal l-deamino-8-d-arginine vasopressin administra-
tion. |
