Osler-Weber-Rendu syndrome

Bleeding in vital areas must be corrected surgically. Frequent or heavy nosebleeds (epistaxis) may be treated with electrocautery or laser surgery. Large collections of abnormal blood vessels (arterio-venous malformations) in the lungs may be deliberately clotted off in a procedure called coiling, which is performed by an interventional radiologist.

Some patients respond to estrogen therapy, which can reduce bleeding episodes. Blood-thinning medications should be avoided. Some patients may need to take antibiotics during simple dental or surgical procedures. Ask your doctor what precautions you should take.

Barring a fatal intracranial hemorrhage, this syndrome is compatible with a normal lifespan. Many patients do not know that they have this condition until a family member is diagnosed with it.

• Internal hemorrhaging
• Marked increased risk for nose bleeds
• Coughing up blood
• Increased risk for strokes and infections of the brain
• Heart failure
• Shortness of breath
• High blood pressure in the lungs (pulmonary hypertension)

Call your health care provider if your child has frequent nose bleeds or other signs of this disease.
