E-mail: Lanzino.Giuseppe@mayo.edu Middle cerebral artery (MCA) aneurysms often have an is used to obliterate 1 portion of the aneurysm and irregular morphology that might require creative clipping a fenestrated clip, with the ring of the fenestration techniques even in the case of small aneurysms. In this circling the body of the first clip, is used to obtain video, we illustrate the case of a patient with an incidental obliteration of the other lobe. This patient also had a but very irregular MCA aneurysm. The presence of contralateral internal carotid artery occlusion, and we 2 separate, asymmetric lobes was dealt with by utilizing discuss the pitfalls of temporary clipping in such a the “interlocking” clip technique in which a regular clip situation.

As such, this video is a good teaching tool, even if it does not drugs, materials, or devices described in this article. provide novel information. Other technical and medical risks, such as the impact of a calcified neck or comorbidities that could complicate surgery or shorten life-expectancy, must be considered when applying COMMENTS this technique. In so doing, the surgeon may carefully weigh these risks against other possible outcomes such as incomplete aneurysm occlusion he authors have provided a well illustrated and well narrated video of T using interlocking clips to secure an unruptured MCA bifurcation with single clip application, endovascular treatment with incomplete aneurysm. This is a fundamental technique that must be a part of every neck coverage or observation with acceptance of natural history risk. The cerebrovascular neurosurgeon’s armamentarium.
