Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - Interventional therapy
Other interventions - Medical management

Experimental: Medical management - Patients with unruptured BAVMs will receive symptomatic medical management alone.

Active Comparator: Interventional therapy - Patients with unruptured BAVMs will receive symptomatic medical management with invasive therapies (any combination of surgery, endovascular embolization, or radiotherapy).


Treatment: Surgery: Interventional therapy
All interventional procedures are standard of care for the treatment of AVMs. They are not experimental. A patient randomized to interventional therapy is expected to begin interventional therapy within 3 months following randomization. Interventional therapy consists of endovascular attempts at occlusion of the nidus and feeding vessels, coiling or microsurgery for feeding artery aneurysms, microsurgery for BAVM itself, and radiosurgery, these alone or in various combinations and timings.

Other interventions: Medical management
Patients participating in the trial will receive the best medical management possible for the disorder being tested in the trial and for any general medical illnesses they are demonstrated to have. One important consideration in the medical management of patients in this trial is stroke risk factor reduction.

Outcomes
Primary outcome [1] 0 0
Difference of 5-year event rates between two arms - The hypothesis to be tested is that there is no difference between medical management and interventional therapy in the time to stroke or death from any cause.
Timepoint [1] 0 0
5 years
Secondary outcome [1] 0 0
Prevalence of the risk of death or clinical impairment at 5 years post-randomization with early intervention - The hypothesis to be tested is that early intervention decreases the risk of death or clinical impairment at 5 years post-randomization. (Rankin Score >/= 2)
Timepoint [1] 0 0
5 years
