Complex aneurysms are a therapeutic challenge in contemporary neurosurgery. Several microsurgical and endovascular techniques have been proposed for their treatment. The picket fence clipping technique uses fenestrated clips, that are stacked not to reconstruct the neck of the aneurysm, but to create a duct to normalize the cerebral flow by reconstructing the dome. We present four illustrative cases using the picket fence clipping technique. The aneurysms considered were of different locations (ICA, MCA, AComA), of large or giant size with wide necks, in which clipping attempt with a conventional technique was not possible, so that the use of non-conventional clipping techniques had to be applied with favorable results. In our experience we found this technique useful in large and giant, wide-necked aneurysms by reconstructing the parent vessel according to the concept of the ideal closure line in these previously unreported locations, thereby restoring normal cerebral circulation. The use of non-conventional techniques for clipping complex aneurysms can be used alone or in combination for adequate treatment, preserving cerebral circulation without compromising adequate exclusion of the aneurysm. The Picket fence technique is a feasible clipping technique that can be used as a less morbid option in large and giant aneurysms with wide necks.
