AbstractTreatment of giant intracranial aneurysms, via either surgical or endovascular approaches, is associated with a high level of technical difficulty as well as a high rate of treatment-related morbidity and mortality. Flow-diverting stents, such as the Pipeline embolization device (PED), have drastically altered the therapeutic strategies for the treatment of giant aneurysms. Gaining endovascular access using a microcatheter to the portion of the parent artery distal to the aneurysm neck is requisite for safe and effective stent deployment. Giant aneurysms are often associated with vascular tortuosity, which necessitates significant catheter support systems to enable maneuvering of PEDs across the aneurysm neck. This is also required in order to reduce the probability of stent herniation within giant aneurysms. We report on a case of a giant supraclinoid internal carotid artery (ICA) aneurysm which was treated successfully with a PED utilizing a balloon anchor technique to facilitate direct microcatheter access across the aneurysm neck.
