Flow Diverter Stent for Endovascular Treatment of Unruptured Saccular Wide-necked Intracranial Aneurysms
Multicenter Randomized Study for Medico-economic Evaluation of Embolization With Flow Diverter Stent in the Endovascular Treatment of Unruptured Saccular Wide-necked Intracranial Aneurysms
Unruptured saccular intracranial aneurysms larger than 7 mm can be treated with endovascular occlusion using detachable coils, with or without expendable stent assistance. A new endovascular technique has recently been developed, using flow diverter stents without associated coils. Clinical results already published are encouraging but have to be confirmed. Furthermore, these medical devices are expensive in comparison to the coiling strategy. The purpose of this study is to compare the clinical efficacy, safety, and cost-effectiveness of endovascular coiling and endovascular flow diversion for unrupted saccular intracranial aneurysms.
Main Outcome Measure: Percentage of patients with an aneurysm with complete occlusion, defined as the absence of visible blood flow to the consideration of angiography performed 12 months post-endovascular intervention.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
