Von Willebrand disease type 3
Von Willebrand disease type 3
Also known as:VWD type 3; severe von Willebrand disease; China Second Rare Disease Catalog item 84
Von Willebrand disease type 3 is the rarest and most severe VWD type, with little or no functional VWF and often low factor VIII, causing recurrent mucosal, soft tissue, joint, and procedure-related bleeding from childhood.

A quick guide to the next step: which department to start with, what to prepare, and what to ask.
Recurrent childhood nosebleeds, gum bleeding, bruising, prolonged wound bleeding, heavy menstrual bleeding, or abnormal bleeding after dental work, surgery, or childbirth should be assessed by hematology.
VWF helps platelets stick and protects factor VIII. In type 3, VWF is extremely low or absent, so nosebleeds, gum bleeding, heavy periods, and hemophilia-like joint or muscle bleeds can occur.
Treatment aims to prevent and control bleeding, usually with VWF-containing factor concentrates. Tranexamic acid may help mucosal bleeding; desmopressin is usually limited or ineffective in type 3 and needs specialist judgment.
Type 3 is usually autosomal recessive, and parents may be carriers. Patients and relatives planning pregnancy should ask about genetic counseling and carrier testing.
Bleeding may be dismissed as frequent nosebleeds or heavy periods, or confused with hemophilia A. Testing only factor VIII without VWF antigen and activity can miss the diagnosis.

Diagnosis Path
Organized around the practical patient journey: identify clues, avoid common delays, then prepare for care.
When to Suspect It
- Recurrent childhood nosebleeds, gum bleeding, bruising, or prolonged bleeding after cuts or dental work.
- Heavy menstrual bleeding, postpartum bleeding, joint or muscle bleeding, or anemia.
- Family history of consanguinity, siblings with bleeding, VWD, or hemophilia-like illness.
Common Wrong Turns
- Treating one organ or one episode without connecting the long-term pattern, family history, and prior results.
- Watching common-disease explanations for too long without referral to the right specialty or rare disease clinic.
- Not keeping imaging, pathology, genetic, treatment, and follow-up records, leading to repeated workups and delays.
Departments to Start With
- Hematology/coagulation clinic
- Pediatric hematology
- High-risk gynecology/obstetrics
- Medical genetics
Before the Visit
- Bring bleeding history, surgical/dental/childbirth bleeding records, transfusion and factor use history.
- Bring CBC, ferritin, APTT, FVIII, VWF antigen, VWF activity, multimer testing, and genetic testing.
- Record menstrual bleeding, anemia, joint or muscle bleeding, and family bleeding history.
Tests to Ask About
- Whether this is type 3 VWD and whether hemophilia A or acquired VWD still needs exclusion.
- Whether a home, school, or workplace bleeding plan and VWF concentrate access are needed.
- How bleeding will be prevented before surgery, dental work, pregnancy, childbirth, and heavy periods.
Questions for the Doctor
- What are my baseline VWF and FVIII levels, and do I need prophylaxis or on-demand treatment?
- Can I use tranexamic acid, menstrual management, or iron, and which medicines should I avoid?
- How should relatives and future children be assessed for genetic risk?
Basic Information
Medical Notes
More complete medical explanations are kept here for discussion with clinicians.
Symptoms
Type 3 VWD can cause recurrent nosebleeds, gum bleeding, bruising, prolonged bleeding after wounds, dental work or surgery, heavy menstrual bleeding, and iron deficiency anemia from childhood. Severe cases can have muscle hematomas, joint bleeds, gastrointestinal bleeding, or major postpartum bleeding.
Because VWF is extremely low, FVIII can also be low, so symptoms may resemble hemophilia A, but all sexes can be affected.
Diagnosis
Diagnosis needs complete coagulation testing: CBC and iron status, APTT, FVIII, VWF antigen, VWF activity, sometimes multimer analysis, and VWF genetic testing. Type 3 usually has extremely low or undetectable VWF and low FVIII.
Clinicians distinguish hemophilia A, platelet function disorders, other VWD types, and acquired VWD. Once confirmed, patients need a personal bleeding emergency and peri-procedure plan.
Treatment
Main treatment is VWF-containing factor concentrate for acute bleeding and before surgery, dental work, or childbirth; prophylaxis may be considered for recurrent severe bleeding. Tranexamic acid can support mucosal bleeding and heavy periods.
Desmopressin is usually not suitable or insufficient for type 3 and should be judged by a coagulation specialist. Avoid unnecessary aspirin and NSAIDs that increase bleeding risk.
Long-term Care
Long-term care tracks bleeding frequency, joint health, anemia and iron deficiency, menstrual management, factor use, inhibitor or allergic reaction risk, and surgery, dental, sport, and travel planning.
Patients should carry diagnosis information and tell emergency, dental, obstetric, and anesthesia teams about type 3 VWD.
Fertility and Family
Type 3 VWD is usually autosomal recessive. Patients, partners, and relatives can consider carrier testing after genetic counseling. Pregnancy and childbirth need coordinated hematology and obstetric planning for factor replacement and postpartum bleeding prevention.
When to Seek Urgent Care
Emergency care is needed for head injury, persistent nosebleed, vomiting blood or black stools, blood in urine, rapidly swelling painful joint or muscle, very heavy periods with dizziness, post-surgical bleeding, or pregnancy/postpartum bleeding.
Prognosis
Specialist care reduces severe bleeding and joint damage; unplanned surgery, childbirth, or trauma can carry high bleeding risk.
