Treatment for giant fusiform aneurysm located in the cavernous segment of the internal carotid artery using the pipeline embolization device

The pipeline embolization device (PED) is a new endovascular device for treatment of complex, fusiform and wide-neck intracranial aneurysms. The main mechanism of this stent is to divert the flow in the parent artery with reduction of inflow in the aneurysm leading to thrombosis. We treated a 40-year-old woman who had left facial pain and orbit discomfort. Angiography showed a giant fusiform aneurysm located in the cavernous segment of the left internal carotid artery. A PED was successfully deployed across the aneurysm. The procedure and post-procedural course were uneventful. After 3 months, angiography showed complete obliteration of the aneurysm with good patency of the branching vessels originating from the deployed segment. The patient's symptoms improved completely without complications.
