Purpose: We examined the outcome of coil embolization for symptomatic unruptured cerebral aneurysms, and investigated factors contributing to symptom relief after surgery.
Methods: We retrospectively reviewed 19 patients who underwent coil embolization between January 2008 and April 2016.
Results: After surgery, symptoms reduced in 13 patients (68%), but not in 6 (32%). In the improved group, the mean duration of disease was significantly shorter than in the unimproved group (1.3 vs. 16.2 months, respectively, p <0.05). There was a significant reduction in the aneurysmal size in the former (mean rate of reduction: 3.51 mm), whereas there was an increase in the latter (mean increase: 1.63 mm) (p <0.05).
Conclusion: Early therapeutic intervention and a postoperative reduction in the aneurysmal size may be important to achieve the relief of symptoms of symptomatic unruptured cerebral aneurysms after surgery.
