Abstract
- Objective To evaluate the efficacy of surgery as a treatment for supratentorial cerebral cavernous malformation–associated epilepsy (SCCMAE) and determine the factors that influence outcomes. Methods During the 5-year period from 2005 to 2009, this study included 181 consecutive patients who were diagnosed with SCCMAE and surgically treated in a single institution. Each patient was followed up for at least 5 years postoperatively. A time-to-event analysis was performed using Kaplan-Meier curves and Cox regression models to evaluate the associated risk factors. Results The age at seizure onset was 30.6 ± 14.3 years, and the age at the time of surgery was 33.4 ± 14.6 years. The female/male ratio was 0.81:1. The mean diameter of the cerebral cavernous malformations (CCMs) was 2.0 cm. For CCMs involving eloquent brain areas, the CCM was removed with (in 14 cases) or without (in 28 lesions) the peripheral hemosiderin. None of the patients had long-term neurologic disabilities. An Engel class I outcome was achieved in 89.0%, 83.4%, 81.8%, and 80.1% of the patients after 6 months, 1 year, 2.5 years, and 5-years of follow-up, respectively. In patients who were class I after 1 year, the prevalence of seizure remission 5 years postoperatively was 96.0% (95% confidence interval, 94.4%–97.6%). Conclusions This study supports the efficacy of using surgery to treat SCCMAE. A shorter duration of preoperative epilepsy was associated with better seizure control after surgery, and patient status at the 1-year follow-up was a reliable indicator of long-term Engel class I epilepsy control.
