This study aimed to validate the usefulness of parent artery complex coil protection for the treatment of wide-neck, side-branched, and ruptured aneurysms. A microcatheter was first introduced into the aneurysmal sac, and another microcatheter was introduced into the parent artery or near the orifice of the branch artery. A framing coil was deployed partially from the first microcatheter, and a protection coil was deployed from the second microcatheter to prevent protrusion of the first framing coil to the parent artery and side branches. After the first framing coil insertion, the protection coil was withdrawn to confirm the stability of the framing coil and blood flow. The procedures with this technique were successful for 3 patients. Parent artery complex coil protection can be an effective and safe coil embolization technique for the preservation of parent and side branch arteries and an alternative method for emergent ruptured cases.
