Bailout Stent Deployment during Coil Embolization of Intracranial Aneurysms

A 68-year-old woman presented with SAH from a right IC-PcomA aneurysm. A double-microcatheter technique was used for coiling of the wide-neck aneurysm. A, Native oblique anteroposterior and lateral views. After detachment of the third coil, encroachment of the coil mesh into the parent artery is noted. B, Due to concerns of parent vessel compromise, a 4 × 15 mm Neuroform stent was deployed at the site of the protruded coil mesh, achieving successful molding of the protruded coil mesh and restitution of the parent artery lumen. Residual protruding coil loop is seen on the lateral view, which is probably tacked to the sidewall by the stent. C, Subtracted views. Good parent vessel patency is maintained without signs of thrombus formation.
