Figure 2. A 52-year-old woman with a rapid onset of deficit of left III cranial nerve. Non-enhanced CT (A) and CT-angio images (B, C) showed a partially thrombosed giant aneurysm of the basilar tip. A frontal angiogram (D) better defined the anatomy of the aneurysm with an acute angulation between the basilar artery and the right PCA [distal landing zone for the flow diverter device (FDD)]. A 0.0165” microcatheter was navigated and looped inside the aneurysm to gain the right PCA (E). An Aperio stent retriever (3.5 mm ´ 28 mm) was fully deployed in the PCA and the microcatheter was removed (F). Over the pushing wire of the stent-retriever, the 0.027” microcatheter was delivered in the right PCA (G). The subtracted frontal image (H) showed the correct deployment of the FDD at the end of the procedure.
