An 81-year-old woman presented with trigeminal neuralgia and diplopia due to abducens nerve palsy. A: An angiogram shows a 26-mm cavernous carotid artery aneurysm. B: After stent-assisted coil embolization, an angiogram shows a neck remnant of the aneurysm. Cranial nerve dysfunction was resolved in 2 months. C: A follow-up angiogram at 6 months after treatment shows an increased neck remnant (arrow).

An 81-year-old woman presented with trigeminal neuralgia (CN V) and diplopia due to abducens nerve palsy (CN VI). An angiogram showed a 26-mm cavernous carotid artery aneurysm (Fig. 1A). An angiogram after SACE showed a neck remnant of the aneurysm (Fig. 1B). A follow-up angiogram at 6 months after treatment showed an increased neck remnant (Fig. 1C), but no additional coiling was required.

A 64-year-old woman presented with trigeminal neuralgia. A: An angiogram shows a 17-mm cavernous carotid artery aneurysm. B: Flat-panel detector computed tomography (XperCT; Philips Healthcare, Best, the Netherlands) shows that a microcatheter is placed in the aneurysm and that an Enterprise stent (Cordis Neurovascular, Miami, Florida, USA) covers the wide neck orifice of the aneurysm. C: After stent-assisted coil embolization, an angiogram shows complete occlusion of the aneurysm. Trigeminal neuralgia was resolved in 1 month. D: A follow-up angiogram at 6 months after the operation shows no recanalization.

A 62-year-old woman presented with trigeminal neuralgia (CN V). An angiogram showed a 17-mm cavernous carotid artery aneurysm (Fig. 2A). We treated the patient with SACE using a jailing technique (Fig. 2B). We were able to insert coils tightly because the Enterprise stent covered the neck orifice of the aneurysm (Fig. 2C). A follow-up angiogram at 6 months after the operation showed complete occlusion of the aneurysm (Fig. 2D).
