Inclusion Terms
- Rendu-Osler-Weber disease
Medical Intelligence & Overview
Hereditary hemorrhagic telangiectasia (HHT), also known as Rendu-Osler-Weber disease, is a genetic disorder that affects blood vessels throughout the body. This condition causes abnormal blood vessel formation, leading to bleeding and other health issues. It is a lifelong condition that can vary greatly in severity, with some individuals experiencing frequent bleeding episodes while others have milder symptoms. Early recognition and management are essential to prevent complications associated with the abnormal blood vessels.
Causes & Symptoms
Clinical Causes: Genetic mutations passed down from parents Inheritance pattern typically autosomal dominant Mutations affect genes responsible for blood vessel development, such as ENG, ACVRL1, and SMAD4 No known environmental or lifestyle factors directly cause the condition, but genetic predisposition is key
Key Symptoms: Frequent nosebleeds (epistaxis) Visible small blood vessels (telangiectasias) on the skin and mucous membranes Bleeding in other organs, including the gastrointestinal tract and lungs Anemia due to chronic blood loss Potential complications like stroke or brain abscess from abnormal blood flow or vessel malformations Additional symptoms may include skin discoloration, fatigue, and swelling
Diagnostic & Treatment
Diagnosis Path: Detailed medical and family history assessment Physical examination for telangiectasias and other signs Endoscopic procedures to identify bleeding sites or abnormal vessels Imaging studies such as MRI or CT scans to detect AVMs (arteriovenous malformations) Genetic testing to identify mutations in associated genes
Treatment Protocols: Nasal cauterization or laser therapy for nosebleeds Supplements like iron to treat anemia Medications such as antifibrinolytics to reduce bleeding episodes Laser therapy or sclerotherapy to obliterate abnormal vessels Surgical interventions for severe AVMs or organ-specific complications Regular monitoring and imaging to detect new or worsening vascular malformations
