Microsurgical Resection for DAVF and AVM

What is microsurgical resection?

Microsurgical resection is a treatment technique reserved for dural arteriovenous fistulas (DAVF) that cannot be closed with endovascular embolization. During microsurgical resection, we perform a craniotomy and, using the microscope, isolate the DAVF or AVM from the tissues around the brain or spinal cord.

Conditions treated with microsurgical resection:

• dural arteriovenous fistulas (DAVF)
• arteriovenous malformations (AVM)

The Johns Hopkins Cerebrovascular Team evaluates each DAVF or AVM patient to decide the best treatment for that patient's specific DAVF or AVM. In special cases, we may opt to use both techniques (microsurgical resection and endovascular embolization) in combination.
