Abstract
Background and Objectives
Although von Willebrand's disease (vWD) is the most common hereditary bleeding disorder in the world, the acquired type of the disease (acquired von Willebrand’s syndrome, AvWs) which is seen in some conditions, is less common. Cardiovascular diseases, use of cardiac assistive devices, lymphoproliferative and myeloproliferative disorders are among the most common disorders associated with AvWs. Despite its low prevalence, AvWS is known as a clinically important bleeding disorder.
Materials and Methods
Considering the importance of the disease, we aimed to investigate and review the disease condition, diagnostic pattern and its clinical and laboratory findings from the disease discovery to the present time by referring to 110 related articles in PubMed, Medline, Scopus and Google Scholar databases.
Results
Clinical and laboratory findings in AvWS and vWD are often similar. So, it can be difficult to distinguish between the two conditions. However, performing screening tests prior to any clinical interventions with a high risk of bleeding, such as surgery, in any individual with an AvWs-associated disorder can greatly facilitate the diagnosis of the disease. Furthermore, a distinction clue between AvWS and vWD is the late onset of AvWS without any previous family and personal history of bleeding.
Conclusions
According to published reports, AvWS has been considered as an uncommon disorder. But it seems that its actual prevalence is not rare and compared to what was previously thought, its prevalence is increasing at least in certain groups of patients, due to awareness of specialists especially hemaologists and cardiologists.
