📚 Von Willebrand Disease — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Von Willebrand disease is the most common inherited bleeding disorder, caused by a deficiency or defect of von Willebrand factor (vWF), which is needed for platelet adhesion and also carries/stabilizes factor VIII. Unlike hemophilia it is usually autosomal and affects both sexes. Bleeding is typically mucocutaneous: easy bruising, nosebleeds, gum bleeding, and heavy menstrual periods.
🔑
Key points
Understand these first
vWF mediates platelet adhesion to injured vessel walls and protects factor VIII from breakdown, so its loss impairs primary hemostasis.
Most common pattern is mucosal bleeding: epistaxis, gingival bleeding, easy bruising, and menorrhagia in women.
Bleeding time and PFA closure time are prolonged; aPTT may be prolonged if factor VIII is also low; platelet count is normal.
Desmopressin (DDAVP) is the first-line treatment for many types because it releases stored vWF and factor VIII.
vWF/factor VIII concentrates are used for severe disease or when DDAVP is ineffective; aminocaproic acid helps mucosal bleeding.
Inheritance is most often autosomal dominant, so it affects males and females roughly equally.
✅
Nursing priorities
What to do, in order
Control mucosal bleeding with direct pressure; for epistaxis have the client sit up and lean forward and apply pressure.
Administer DDAVP or vWF-containing factor concentrate as prescribed before procedures or for active bleeding.
Implement bleeding precautions and avoid IM injections, aspirin, and NSAIDs.
Monitor for and quantify blood loss, especially menstrual bleeding, and assess for anemia.
Hold pressure on venipuncture and injection sites longer than usual.
🚩
Red flags — report now
Escalate immediately
Heavy or uncontrolled bleeding, signs of significant blood loss (tachycardia, hypotension, dizziness) require prompt reporting.
Never administer aspirin, NSAIDs, or antiplatelet agents.
Sudden severe internal bleeding signs (abdominal pain, GI bleeding) warrant immediate evaluation.

Patient teaching
What patients must know
Avoid aspirin, NSAIDs, and other platelet-inhibiting medications; use acetaminophen for pain.
Women with heavy periods may benefit from hormonal therapy; report excessive menstrual bleeding.
Carry medical alert identification and notify dentists/surgeons before any procedure.
Apply prolonged pressure to cuts and nosebleeds; keep DDAVP available if prescribed.
Genetic counseling is appropriate as the condition is inherited.

What are the priority nursing interventions for Von Willebrand Disease?
Control mucosal bleeding with direct pressure; for epistaxis have the client sit up and lean forward and apply pressure. Administer DDAVP or vWF-containing factor concentrate as prescribed before procedures or for active bleeding. Implement bleeding precautions and avoid IM injections, aspirin, and NSAIDs. Monitor for and quantify blood loss, especially menstrual bleeding, and assess for anemia.
What are the warning signs of Von Willebrand Disease a nurse must report?
Heavy or uncontrolled bleeding, signs of significant blood loss (tachycardia, hypotension, dizziness) require prompt reporting. Never administer aspirin, NSAIDs, or antiplatelet agents. Sudden severe internal bleeding signs (abdominal pain, GI bleeding) warrant immediate evaluation.
