Pseudo-von Willebrand disease

Disease definition

Platelet type Von Willebrand disease (PT-VWD) is a bleeding disorder characterized by mild to moderate mucocutaneous bleeding, which becomes more pronounced during pregnancy or following ingestion of drugs that have anti-platelet activity. PT-VWD is due to hyperresponsive platelets, resulting in thrombocytopenia.
