Case Report: Thrombosis of a ruptured fusiform basilar apex aneurysm after stenting and selective coiling

Large fusiform and dissecting type intracranial aneurysms represent a challenge to both endovascular as well as microsurgical treatment approaches. Those involving the upper basilar artery and basilar apex represent a particular challenge. In many cases these aneurysms are not amenable to intravascular coiling without occluding the parent vessel. Clip reconstructions of such aneurysms are technically difficult, and are also associated with a high probability of morbidity and mortality. We present an interesting case involving a ruptured fusiform aneurysm of the basilar apex.
