Congenital systemic arteriovenous fistula (AVF) is a rare vascular malformation that occurs when an abnormal connection forms between an artery and a vein. This connection bypasses the normal capillary bed, allowing blood to flow directly from the artery to the vein. This can lead to high blood pressure, increased blood flow, and other complications.

The symptoms of Congenital systemic arteriovenous fistula can vary depending on the location and severity of the fistula. Common symptoms include:

-High blood pressure
-Heart murmur
-Headache
-Fatigue
-Shortness of breath
-Palpitations
-Chest pain
-Lightheadedness
-Fainting
-Swelling in the legs and feet
-Abnormal heart rhythms
-Abnormal blood flow in the lungs
-Abnormal blood flow in the brain
-Abnormal blood flow in the liver
-Abnormal blood flow in the kidneys
-Abnormal blood flow in the intestines
-Abnormal blood flow in the spleen
-Abnormal blood flow in the pancreas
-Abnormal blood flow in the bladder

Congenital systemic arteriovenous fistula is a rare condition that is caused by a malformation of the blood vessels. It is usually caused by a genetic mutation, but can also be caused by environmental factors such as radiation exposure or certain medications. In some cases, the cause is unknown.

1. Surgical repair: This is the most common treatment for congenital systemic arteriovenous fistula. During this procedure, the surgeon will close off the abnormal connection between the artery and vein.

2. Endovascular embolization: This procedure involves using a catheter to inject a special material into the abnormal connection to block it off.

3. Medical management: In some cases, medications may be used to help manage the symptoms of a congenital systemic arteriovenous fistula. These medications may include beta-blockers, ACE inhibitors, and diuretics.

1. Congenital heart defects
2. Genetic syndromes
3. Maternal diabetes
4. Maternal hypertension
5. Maternal smoking
6. Maternal drug use
7. Maternal infections
8. Premature birth
9. Low birth weight
10. Family history of congenital systemic arteriovenous fistula

There is no cure for congenital systemic arteriovenous fistula, but medications can be used to manage symptoms. Medications such as beta-blockers, calcium channel blockers, and ACE inhibitors can be used to reduce the risk of complications such as stroke, heart failure, and high blood pressure. Surgery may also be recommended to close the fistula.
