Arteriovenous Fistula
Treatment of arteriovenous fistula using advanced catheterization techniques.
An arteriovenous fistula is an abnormal connection between an artery and a vein, allowing blood to flow directly from the artery to the vein without passing through capillaries.
Arteriovenous fistulas are treated using interventional catheterization techniques, where a special catheter is inserted to close the abnormal connection. This procedure is performed under general anesthesia and typically takes 1-2 hours.
This treatment is a safe alternative to traditional surgery, as it does not require large incisions. Patients can usually return home the same day or the next day.
Ultrasound and magnetic resonance imaging are used to diagnose and plan the treatment. Some patients may need multiple treatment sessions to achieve the best results.

Frequently Asked Questions
What is an arteriovenous fistula?
It is an abnormal connection between an artery and a vein, allowing blood to flow directly from the artery to the vein without passing through capillaries.
What are the symptoms of arteriovenous fistula?
Symptoms may include swelling, pain, skin color changes, abnormal pulse, or circulatory problems.
How is arteriovenous fistula diagnosed?
Diagnosis is made through clinical examination, ultrasound, computed tomography, or angiography.
Are there risks to the treatment?
Yes, there are potential risks such as bleeding, infection, or blood vessel damage. However, these risks are lower than with traditional surgery.
What is the recovery period?
Most patients can return to normal activities within 1-2 days. Your doctor may recommend avoiding strenuous activities for a certain period.
Is the treatment permanent?
Yes, the treatment aims to permanently close the fistula. However, some patients may need regular follow-up to ensure treatment success.
Can arteriovenous fistula be prevented?
Most cases of arteriovenous fistula cannot be prevented as they are usually present from birth or develop after injury or medical procedures.
What are the signs of successful treatment?
Signs of success include disappearance of symptoms, improved blood flow, and absence of abnormal artery-vein connection in follow-up examinations.
Can the fistula return after treatment?
In rare cases, the fistula may return after treatment. Therefore, regular follow-up with your doctor is important.
What are the risk factors for arteriovenous fistula?
Risk factors include injuries, previous surgeries, certain genetic conditions, and diseases affecting blood vessels.
