Endovascular treatment of ruptured anterior communicating aneurysms: a 17-year institutional experience with coil embolization.

Endovascular treatment of ruptured ACoA aneurysms is safe and is associated with low mortality and retreatment rates. Younger patients with favorable functional status and larger aneurysm size are more likely to be retreated. Ruptured aneurysms <4 mm, although prevalent in the study (29%), never required retreatment.
