Surgical resection of intracranial arteriovenous malformations.
Deliver a relatively high dose of focused radiation precisely to the arteriovenous malformations.
Deliver embolic materials to the feeding arteries or the nidus by microcatheters
Use two or three methods ( Surgical treatment stereotaxic radiosurgery endovascular treatment ) to cure the intracranial arteriovenous malformations
Patients refused to any of the treatment above
Intracranial arteriovenous malformations are congenital lesions that consist of multiple arteries and veins, connecting as a fistula without intervening normal capillary bed. The treatment strategy including surgical removal, endovascular embolism and stereotaxic radiosurgery and comprehensive treatment. China is a united multi-ethnic nation of 56 ethnic groups, and has the largest population in the world. We have most extensive and valuable clinical resources of intracranial arteriovenous malformation in the world. But we know little about the current treatment situation of the disease in China.
In order to realize the treatment situation of intracranial arteriovenous malformation in China, we designed a retrospective and prospective register study to collect the treatment and outcome information all over China.
