OBJECTIVE: The authors report a retrospective analysis of their experience in the endosaccular embolization of internal carotid @entity439 which caused mass effect symptoms of @entity129 ( @entity129 ) and review the efficacy and limitations of this technique. METHODS: Between April 1997 and August 2002, 12 internal carotid @entity439 that caused mass effect symptoms of @entity129 were treated by @entity887 with parent artery preservation. The locations were the cavernous internal carotid artery (CV) in six @entity1 , carotid-ophthalmic artery (CO) in two @entity1 , and posterior communicating artery (PCo) in four @entity1 . The angiographical size of the @entity439 ranged from 6 to 20 mm, with a mean of 13.3 mm. Duration of symptoms ranged from 0.5 to 120 months, with a mean of 13.7 months. All @entity439 were treated by endosaccular guglielmi detachable coil (GDC) embolization with preservation of the internal carotid artery. RESULTS: Five @entity1 (42%) had complete resolution of symptoms, four (33%) had significant improvement of symptoms, and three (25%) were unchanged. Immediate posttreatment angiographic studies revealed neck remnant (NR) in nine @entity1 and dome filling (DF) in three @entity1 . In one @entity1 (case 10), the resolved symptoms became worse 29 months later. Follow-up angiograms were obtained in 10 @entity1 , and recanalization was observed in four of them (40%). Transient @entity715 occurred in only one @entity1 . The group with resolution or improvement of symptoms demonstrated a shorter duration of symptoms before GDC treatment (< or = 12 months). CONCLUSION: Even subtotal endosaccular embolization of @entity439 may reduce mass effect symptoms of @entity129 . However, careful follow-up is needed because @entity432 carries a future risk of growth.
