Clipping Versus Coil

Introduction: Currently, there are two available methods for aneurysms treatment, endovascular and microsurgery. The publication of ISAT has been producing a tendency towards coiling in spite of methodological mistakes and misinterpretation. The objective of this study is to discuss the current treatmentof the cerebral aneurysms , considering the conclusions of ISAT review and perhaps enhancing its influence in the contemporary treatment of intracranial aneurysms. Matherial and Methods: The authors carried out a review of theliterature.studying articles and discussing the results of ISAT aiming to perform a critical analysis of its methodology and practical interpretations of these results. Results: Due to the controversial methodology, incongruous criteria of selection, statistical faults, no quantification of the secondary outcome,ISAT review was not able to provide definitive answers about the ideal treatment to the intracranial aneurysms. Conclusions: No conclusions can be formulated confirming the superiority of coiling over clipping. Generalization and acceptance of ISAT conclusions are precocious and it is not in thebest interest of patients harboring intracranial aneurysms.
