1.What does interventional embolization of dural arteriovenous fistula mean? It is a treatment method to eliminate a lesion or reduce a malformed vascular mass by introducing various embolic substances (spring coils, real wire segments, Glubra, NBCA, ONYX gel, etc.) into the blood supplying arterial fistula or venous sinus through the arterial or venous system. 2.Which patients need dural arteriovenous fistula interventional embolization treatment? ①Patients with a history of bleeding; ②Patients with intracranial vascular murmurs that are difficult to tolerate; ③Patients with progressive neurological deficits; ④Patients with local compression symptoms; ⑤Patients with increased intracranial pressure. Advantages ①Minimally invasive to the whole body: less trauma to the brain tissue, no craniotomy, short operation time. ②No damage to the normal blood vessels around the vessels, which can reduce the complications of surgery. ③It can directly cure AVF. ④It creates favorable conditions for surgical resection or provides favorable conditions for radiation therapy. ⑤As a purely palliative treatment, it reduces the chance of rebleeding, improves cerebral blood supply, and alleviates patients’ symptoms. Disadvantages ①It is often difficult to eradicate the disease at one time and requires multiple interventions. ②In cases of severe vascular tortuosity, it is difficult to place the interventional catheter. ③The risk of embolism formation at the distal end of the draining vein, or breakthrough of normal perfusion pressure.
