Arteriovenous Malformations, Cerebral | Procedure: Interventional therapy Other: Medical management | Phase 3 |
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.

Arm | Intervention/treatment |
---|---|
Experimental: Medical management
Patients with unruptured BAVMs will receive symptomatic medical management alone.
|
Other: 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. |
Active Comparator: Interventional therapy
Patients with unruptured BAVMs will receive symptomatic medical management with invasive therapies (any combination of surgery, endovascular embolization, or radiotherapy).
|
Procedure: 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: 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. |
- Difference of 5-year event rates between two arms [ Time Frame: 5 years ]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.
- Prevalence of the risk of death or clinical impairment at 5 years post-randomization with early intervention [ Time Frame: 5 years ]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)
