Coil embolization of intracranial aneurysms

SINCE THE INTRODUCTION of Guglielmi detachable coils more than a decade ago, the coiling technique for the treatment of intracranial aneurysms has been enhanced with technical and technological refinements. Both neurosurgeons and neuroradiologists have participated in this process. Stents and nondetachable balloons have been useful in the coiling of some wide-necked aneurysms. An increasing number of neurosurgeons are pursuing fellowship training in neuroendovascular techniques. Moreover, most neurosurgeons work closely with neurointerventionists. In this communication, technical preferences developed during our experience with intracranial aneurysm coiling are summarized.
