Although endovascular embolization has become the main treatment option for intracranial aneurysms,1 2 wide-necked intracranial aneurysms remain difficult to coil.3 Both stent- and balloon-assisted coiling are used for wide-necked aneurysms because they provide a scaffold that protects the parent vessel during coiling.4 5 However, stent-assisted coiling requires dual antiplatelet therapy, which increases the risk of bleeding, whereas balloon-assisted coiling temporarily obstructs blood flow.4 6 7 The Comaneci device (Rapid Medical, Yokneam, Israel) has recently received US Food and Drug Administration approval as a ‘temporary coil embolization assist device’.5 It temporarily covers the aneurysm neck and allows safe coiling, avoiding the disadvantages mentioned above.6–8 A potential complication of Comaneci-assisted coiling is coil retention when it adheres to the device on recapture; this complication should be promptly recognized and managed.5 9 10 In this video, we present an unusual case of coil retention with the Comaneci device (Video 1).
