A Nationwide Treatment Survey of Intracranial Arteriovenous Malformation: a Multicenter Retrospective and Prospective Register Study in China


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.
