Embolization of cerebral arteriovenous malformations is a treatment that uses various materials to occlude the malformed vascular mass or blood supply artery via the endovascular route. In recent years, this treatment has evolved significantly due to advances in various materials, including embolization materials and catheter guidewires, and has become one of the leading treatments for cerebral arteriovenous malformations, as it has changed many high-grade arteriovenous malformations from untreatable to treatable, and low-grade arteriovenous malformations have become significantly less risky or relatively simple to treat. The most important feature of this approach is that it can be accomplished through a small incision of about 5 mm at the base of the thigh. This is accomplished by inserting a catheter through the arterial sheath at the cerebral angiogram if the diagnosis is clear, placing it along the thoracoabdominal artery in the carotid artery, inserting a microcatheter through the catheter with an outer diameter of only about 0.5 mm at the head end, and delivering the head end of the microcatheter to the artery supplying the arteriovenous malformation until it is very close to the malformed mass, and then injecting embolic material through the microcatheter to block the arteriovenous malformation. The embolic material is then injected through the microcatheter to occlude the blocked malformed vascular mass. In the past, embolization materials such as real wire segments and pellets were used, but because of the large size of these materials, they can only embolize the blood supply artery and part of the malformed mass with the possibility of recanalization, and are currently used only for embolization of combined high-flow fistulas. Currently, the commonly used materials are spring ring and polymeric glue. Polymeric glue is a liquid embolization material, which can be injected through the arterial end and then diffused into the whole malformation mass, and it can be coagulated after entering the blood vessel and contacting the blood, so that the malformation mass can be embolized to the maximum extent. These liquid embolic materials are permanent embolic materials, and no recanalization will occur in any vessel that is diffused and blocked by the glue. Previously, this technique was used only as a supplement to microsurgical resection of cerebral arteriovenous malformations, mainly for the treatment of cerebral arteriovenous malformations in important functional areas or for partial embolization prior to surgery of large cerebral arteriovenous malformations to reduce the volume and blood supplying arteries. Patients are recommended to undergo embolization first. Currently, with advances in materials and interventional techniques, the vast majority of cerebral arteriovenous malformations can be cured by interventional embolization to eliminate or minimize the risk of bleeding, combined with stereotactic radiotherapy. In recent years, methodological improvements have also made it possible for some patients to achieve complete cure by endovascular embolization therapy alone.
