Advanced reconstructive endovascular techniques for the treatment of cerebral aneurysms

Endovascular treatment of cerebral aneurysms with detachable coils has now been proven to be a superior alternative to open microsurgery in terms of disability-free survival 1 year following treatment. Despite this, recurrence due to recanalization of these aneurysms in 10-20% of patients after coiling is still the main drawback of the endovascular technique. In the last 5 years, access devices and endovascular tools based on new concepts, materials and endovascular reconstruction techniques that go beyond simply coiling have been described for cerebral aneurysm treatment, especially for more complicated broad-necked, fusiform and large/giant aneurysms. In this article, we review our recent experience in the treatment of complex cerebral aneurysms by means of multiple novel endovascular techniques for arterial reconstruction.
