Endovascular coil embolization has become an accepted and often first-line treatment for ruptured and unruptured intracranial aneurysms. While the complications of endovascular therapy of intracranial aneurysms have been well vetted in the literature, there are few reports solely concerning the complications and salvage techniques related to either the technical aspects of coil deployment or to the devices themselves. In this review the structural details of commonly used endovascular coils, technical complications related to coiling and salvage techniques used when these complications occur are discussed.
