Arteriovenous fistulas (AVFs) represent abnormal connections between arteries and veins, bypassing the usual capillary network. In interventional neurology, AVFs are particularly relevant when they occur in the cerebral vasculature. These aberrant connections can lead to altered blood flow patterns, potentially causing neurological complications such as hemorrhage or ischemia. Diagnosis often involves neuroimaging techniques like angiography and magnetic resonance imaging (MRI). Interventional neurology procedures, such as endovascular embolization, aim to treat AVFs by blocking the abnormal connections and restoring normal blood flow. Accurate diagnosis and targeted interventions play a pivotal role in managing AVFs and preventing associated neurological complications.
