IX. Follow-up

Postoperative DSA is essential to confirm the complete resection of the AVM. If the DSA confirms the complete resection, the AVM rarely reoccurs, except in pediatric patients. For those patients, the DSA must be repeated five years after the initial treatment.
The natural history of AVMs partially treated or residual is the same for lesions that are not treated; therefore the partial treatment is rarely justified. Residual or recurrent AVMs need to be evaluated for further treatment, and the risk should be individually analyzed.
