Dural arteriovenous fistula
Dural Arteriovenous Fistula
Dural arteriovenous fistula (pronunciation: du-ral ar-teer-e-o-ven-ous fis-tu-la), often abbreviated as DAVF, is a rare, abnormal connection between an artery and a vein in the tough covering over the brain or spinal cord (the dura mater).
Etymology
The term "Dural arteriovenous fistula" is derived from the Latin dura mater (hard mother), referring to the outermost layer of the meninges, and the Latin arteria and vena, referring to the blood vessels involved. The term fistula is from the Latin fistula meaning pipe or tube, indicating an abnormal connection.
Symptoms
Symptoms of a DAVF can vary depending on the location and type of fistula. They may include headache, tinnitus (ringing in the ears), vertigo (dizziness), seizure, and neurological symptoms such as weakness, numbness, or vision problems.
Diagnosis
Diagnosis of a DAVF typically involves neuroimaging techniques such as MRI (Magnetic Resonance Imaging) or CT scan (Computed Tomography). Angiography is often used to confirm the diagnosis and to guide treatment.
Treatment
Treatment options for DAVF include endovascular therapy, radiosurgery, and open surgery. The choice of treatment depends on the location and type of the fistula, as well as the patient's overall health.
Prognosis
The prognosis for DAVF varies depending on the location and type of the fistula, as well as the patient's overall health. With appropriate treatment, many patients can expect a good outcome.
