Surgical clipping is an invasive and technically challenging procedure involving a craniotomy
Endovascular coiling often yields poor results, coupled with a long occlusion time and risk of aneurysm puncture during device deployment
Endovascular flow divertors require an anti-platelet drug regimen and are limited to treatment of aneurysms occurring along the artertial wall
Cerebral aneurisms are often found in arteries known for their tortuous anatomy, small vessel diameter, and uniquely delicate neurovascular structure
Most occur at a Y-branch in the vasculature as opposed to along the arterial wall
Efficacy is measured by obliteration of the aneurysm, absence of any blood flow into aneurysm, or recurrence1
