The dysplastic giant aneurysm with wide neck is a difficult complex aneurysm surgery, the use of endovascular therapy in this pathology is promising and waffle cone technique is very useful in those in wich when we use a Stent and it is impossible to exceed the distal end of the aneurysm neck. A woman patient of 73y,  housewife with disease duration of 5 days, headache associated with neck stiffness and cranial nerve VI paresis of the left was studied. The brain CT showed subarachnoid hemorrhage in the left sylvian valley and an image suggestive of a giant aneurysm of left carotid siphon. The angiographic study concluded giant-ophthalmic aneurysm ruptured left and right paraoftálmic large aneurysm not broken.

The treatment of choice for aneurismal disease is still under discussion, but in the case of giant aneurysm endovascular techniques may achieve optimal results without major complications, endovascular technique waffle cone through the use of Stents is very useful and should extend its use in those dysplastic giant aneurysm with wide neck do not allow the stent to achieve beyond the distal aneurismal neck and both nest in the pouch is able to embed a Neuroform Stent-in the neck of the aneurysm to proceed to use coils of different dimensions to completely embolize the aneurysm. The disadvantages of this technique are the potential for drilling and higher rate of recanalization caused by changes in arterial blood flow. Waffle cone technique is particularly useful in those dysplastic giant aneurysms with wide neck in wich the structure of the aneurysm does not allow the location of the stent at the distal end of its neck.
