Objective: The coil-assisted technique (CAT) for delivering the wire or catheter to the vessel distal to large wide-neck intracranial aneurysms is described.
Case Presentations: We present three cases treated with this technique. The first coil placed in the aneurysm without detaching is used as a support of the wire or catheter in its passing through the aneurysmal neck. This technique was used in order to deliver a guidewire and a balloon catheter in two cases, and to deploy neck-bridge stent in one case.
Conclusion: CAT can be performed simply by changing the order of procedure without any use of additional devices. We think this technique might be useful in treating wide-neck intracranial aneurysms in order to get the distal vessel safely.
