Spinal dural arteriovenous fistula (DAVF) is a rare condition that involves abnormal connections between arteries and veins in the spinal cord’s dura, which is a protective layer surrounding the spinal cord. This can cause symptoms such as back pain, weakness or numbness in the legs, or problems with bowel or bladder function.
The condition can be diagnosed through MRI and spinal angiography. It is serious condition and needs to be treated as early as possible. Treatment options may include endovascular embolization or surgery.
Endovascular embolization is first treatment of choice. It is a minimally invasive procedure that involves the injection of glue into the blood vessels to block the abnormal connections between arteries and veins. The procedure is typically performed by an interventional radiologist and is done with the aid of X-ray guidance.
Surgery may be recommended when embolization is not feasible. The goal of surgery is to disconnect the abnormal blood vessels and restore normal blood flow to the spinal cord.
If you are experiencing symptoms of a DAVF, it is important to seek medical attention to determine the underlying cause and to discuss treatment options with your Interventional Radiologist. Early diagnosis and treatment can help to prevent further damage to the spinal cord and improve outcomes.
