Primary Outcome Measures:
  • Composite event of death from any cause or symptomatic stroke (hemorrhage or infarction confirmed by imaging) [ Time Frame: from enrollment to study end for primary outcomes of death or symptomatic stroke including hemorrhage ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Risk of death or clinical impairment (Rankin Score >/= 2) at 5 years post-randomization [ Time Frame: from enrollment to study end for primary outcomes of death or symptomatic stroke including hemorrhage ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 400
Study Start Date: October 2006
Estimated Study Completion Date: July 2017
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: 1

Symptomatic medical management alone:

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.

Active Comparator: 2

Symptomatic medical management with invasive therapies (any combination of surgery, endovascular embolization, or radiotherapy):

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.

Procedure: invasive therapy [endovascular procedures, neurosurgery, or radiotherapy, alone or in combination]

All interventional procedures are standard of care for the treatment of AVMs. They are not experimental.

Endovascular procedures involve specially designed catheters/tubes position in the small arteries feeding blood to the AVM. The tubes are inserted into an artery in the groin and threaded up through the artery into the brain. Once positioned, the physician injects a special material that changes from liquid to solid very quickly. Once it solidifies, it blocks the artery that is feeding blood to the AVM.

Neurosurgery involves the opening of a portion of the skull and the brain's outer lining to get access to the AVM.

Radiosurgery involves high energy radiation (like X-rays) carefully targeted at the brain AVM to shrink it and, in the best results, eventually eliminate the artery-to-vein links and the risk of bleeding. The effect often takes one to two years to occur.

Detailed Description:

Brain arteriovenous malformations (BAVMs) are an infrequent but important cause of stroke, particularly in a young population. Current invasive treatment strategies are varied and include endovascular procedures, neurosurgery, and radiotherapy. All of these treatments are administered on the assumption that they can be achieved at acceptably minor complication rates, decrease the risk of subsequent hemorrhage, and lead to better long-term outcomes.

Recent data from the literature comparing initial presentation and outcome for patients with ruptured and unruptured BAVMs have raised the possibility that such elective invasive treatment for unruptured BAVMs may yield worse outcomes than managing patients symptomatically with therapy. Unfortunately, no controlled clinical trials have yet been undertaken for management of unruptured BAVMs to address these concerns. Therefore, the goal of this randomized controlled trial is to determine if the long-term outcomes of patients who receive medical management for symptoms (e.g., headache, seizures) associated with an unruptured BAVM are superior to those who receive medical management and invasive therapy to eradicate the BAVM.

Participants will be randomly assigned to receive either symptomatic medical management alone or such management with invasive therapies (any combination of surgery, endovascular embolization, or radiotherapy). Functional assessment will be carried out at the time of randomization, pre-intervention and 48-hour post-intervention, and for all participants at 1 month, and at 6 month intervals throughout the follow up period which will be a minimum of 5 years.

Exclusion Criteria:

  • Patient has evidence of recent or prior BAVM hemorrhage
  • Patient has received prior BAVM therapy (endovascular, surgical, radiotherapy)
  • Patient has BAVM deemed untreatable by local investigator, or has concomitant vascular or brain disease that interferes with/or contradicts any invasive therapy type (stenosis/occlusion of neck artery, prior brain surgery/radiation for other reasons)
  • Patient has baseline Rankin ≥2
