In von Willebrand disease, which clinical scenario is most commonly observed?

• A. Excessive bleeding after dental extraction
• B. Severe thrombotic events
• C. Hypertension
• D. Hypercoagulability

Answer: (A)

VWD causes bleeding from mucous membranes because von Willebrand factor is essential for platelets to adhere to damaged vessel walls, supporting the formation of a stable platelet plug. The scenario most commonly seen is excessive bleeding after dental extraction, since the gingival/mucosal tissues bleed readily and a deficiency in vWF makes primary hemostasis inefficient, leading to prolonged or difficult-to-control bleeding after minor procedures like tooth removal. VWF also stabilizes factor VIII, so a mild rise in bleeding tendency can accompany slightly lowered factor VIII, but the hallmark in clinical presentation is mucosal bleeding after procedures such as dental extraction. Severe thrombotic events, hypertension, or a general hypercoagulable state are not typical features of von Willebrand disease, which mainly manifests as bleeding rather than clotting.
