Rendu-Osler-Weber Syndrome: Causes, Signs, and Treatment
Rendu-Osler-Weber Syndrome, also known as hereditary hemorrhagic telangiectasia (HHT), is a rare genetic disorder that affects blood vessels throughout the body. The primary impact of this syndrome is the development of abnormal blood vessels, which can lead to various complications and health issues. These abnormal blood vessels are prone to bleeding and can cause problems in different organs, potentially affecting overall health and well-being.
What are the Symptoms of Rendu-Osler-Weber Syndrome
Rendu-Osler-Weber Syndrome is characterized by a range of symptoms affecting different parts of the body, typically involving the blood vessels.
- Nosebleeds
- Skin discoloration
- Telangiectasias (small red spots on the skin)
- Bleeding in the digestive tract
- Enlarged liver
- Enlarged spleen
- Arteriovenous malformations

Get Second OpinionCauses of Rendu-Osler-Weber Syndrome
Rendu-Osler-Weber Syndrome, also known as hereditary hemorrhagic telangiectasia, is primarily caused by genetic mutations affecting blood vessels, leading to abnormal formation and fragility of the small blood vessels throughout the body.
- Genetic mutation
- Hereditary factors
- Abnormal blood vessel formation
Types of Rendu-Osler-Weber Syndrome
Rendu-Osler-Weber Syndrome typically manifests as a combination of vascular abnormalities affecting various parts of the body.
- Cutaneous Telangiectasia: Characterized by the presence of small, red lesions on the skin caused by dilated blood vessels.
- Epistaxis: Refers to recurrent nosebleeds, a common symptom of RenduOslerWeber Syndrome due to fragile blood vessels in the nose.
- Gastrointestinal Bleeding: Involves bleeding in the digestive tract, which can lead to symptoms like blood in the stool or black, tarry stools.
- Pulmonary Arteriovenous Malformations: Abnormal connections between arteries and veins in the lungs, which can cause complications like shortness of breath and low oxygen levels.
- Cerebral Arteriovenous Malformations: Abnormal connections in the brain between arteries and veins, which may lead to neurological symptoms such as headaches, seizures, or strokes.
Risk Factors
Rendu-Osler-Weber Syndrome, also known as hereditary hemorrhagic telangiectasia, is primarily caused by genetic mutations and can be inherited, with risk factors including a family history of the condition.
- Family history of RenduOslerWeber Syndrome
- Genetic mutations in the ENG or ACVRL1 genes
- Female gender
- Advancing age

Diagnosis of Rendu-Osler-Weber Syndrome
Rendu-Osler-Weber Syndrome is typically diagnosed through a combination of medical history, physical examination, and specific tests.
- Imaging tests, such as CT scans or MRIs
- Genetic testing
- Endoscopy
- Lung function tests
- Blood tests
- Physical examination
Treatment for Rendu-Osler-Weber Syndrome
Rendu-Osler-Weber Syndrome is managed through treatment aimed at addressing symptoms and preventing complications.
- Laser Therapy: Laser treatment can help reduce and manage abnormal blood vessels in RenduOslerWeber Syndrome, minimizing the risk of bleeding and other complications.
- Embolization: This procedure involves blocking abnormal blood vessels to prevent bleeding episodes in individuals with RenduOslerWeber Syndrome.
- Iron Supplementation: Iron supplements may be prescribed to manage anemia caused by chronic bleeding associated with RenduOslerWeber Syndrome.
- Nasal Spray: Nasal sprays containing medications to promote blood vessel healing may be used to alleviate nosebleeds, a common symptom of RenduOslerWeber Syndrome.
- Regular Monitoring: Regular checkups and monitoring by healthcare providers are essential to assess the progression of RenduOslerWeber Syndrome, manage symptoms, and adjust treatment plans as needed.

What is Rendu-Osler-Weber Syndrome?
Rendu-Osler-Weber Syndrome, also known as Hereditary Hemorrhagic Telangiectasia (HHT), is a genetic disorder that causes abnormal blood vessel formation.
What are the symptoms of Rendu-Osler-Weber Syndrome?
Symptoms may include nosebleeds, telangiectasias (small red spots on the skin), and arteriovenous malformations (AVMs) in various organs.
How is Rendu-Osler-Weber Syndrome diagnosed?
Diagnosis is typically based on clinical evaluation, family history, and imaging studies such as CT scans, MRIs, or angiography.
What are the treatment options for Rendu-Osler-Weber Syndrome?
Treatment focuses on managing symptoms and complications, which may include medications, laser therapy, embolization, or surgery.
Is Rendu-Osler-Weber Syndrome hereditary?
Yes, Rendu-Osler-Weber Syndrome is an autosomal dominant genetic disorder, meaning a child has a 50% chance of inheriting the mutated gene from an affected parent.
