What is Takayasu arteritis?
Takayasu arteritis is a rare condition that causes inflammation in the body’s large arteries. It most often affects the aorta, the main blood vessel that carries blood from the heart to the rest of the body. Over time, the inflammation can narrow or weaken blood vessels and reduce healthy blood flow.
The exact cause of Takayasu arteritis is not fully understood. Takayasu arteritis is most often diagnosed in younger women, but it can affect people of any age or background. Genetics and certain environmental triggers may increase the risk of developing the condition.
Symptoms
Symptoms can develop slowly and may vary depending on which arteries are affected. Some people first notice general signs of inflammation before circulation problems appear.
Common symptoms may include:
- Fatigue
- Fever
- Unexplained weight loss
- Muscle or joint pain
- Chest pain
- Shortness of breath
- Dizziness or fainting
- Weakness or pain in the arms or legs during activity
- Cool or numb hands and feet
- Headaches or vision changes
- High blood pressure
How is it diagnosed?
Diagnosing Takayasu arteritis can be challenging because its symptoms are similar to many other conditions. A healthcare provider will begin with a physical exam and discussion about your symptoms and medical history.
Your provider may check blood pressure in both arms, evaluate your pulse, and listen for unusual sounds in the arteries. Blood tests can help identify signs of inflammation. Imaging tests are often used to look closely at blood vessels and check for narrowing or damage. These tests may include ultrasound, CT angiography (CTA), magnetic resonance angiography (MRA), or traditional angiography.
How is it treated?
Treatment focuses on reducing inflammation and protecting the arteries from further damage. Many people begin treatment with corticosteroid medications to control immune system activity and relieve symptoms.
If additional treatment is needed, immunosuppressant or biologic medications may help manage the disease long term. Regular follow-up visits and imaging tests are important to monitor blood vessel health and watch for complications.
In severe cases, procedures such as angioplasty or vascular bypass surgery may be recommended to restore blood flow through narrowed arteries.
Because Takayasu arteritis is usually a long-term condition, ongoing care is important. With early diagnosis and consistent treatment, many people are able to manage symptoms and maintain an active lifestyle.
