| Popis: | It is well known that corpus callosotomy (CC) can bring a favorable seizure control outcome for disabling generalized seizures, but the complete remission rate achieved by CC is rarely reported, and the postoperative relapse pattern is still not clear. In this study, the authors reviewed patients with medically refractory epilepsy who were suffering disabling seizures, including drop attacks, generalized tonic-clonic seizures (GTCS), tonic seizures, atonic seizures, atypical absences, and complex partial seizures. The patients underwent anterior two third or complete CC in our hospital. Seizure control outcome was evaluated postoperatively at 2 weeks, 1 month, 3 months, 6 months, thereafter, at yearly intervals. Seizure-free or >90% reduction was considered to be satisfactory. There were 14 patients with mean age 11.00 ± 6.34 at surgery. Of all the patients, 6 patients underwent anterior two third CC, and the other 8 patients underwent complete CC. All the patients were postoperatively followed up for at least 1 year. Four patients (28.57%) were free of all seizure types in the first year after surgery. Among the 9 patients with follow-up longer than 3 years, 2 patients (22.22%) were free of all seizure types. In the first 3 months after surgery, more than half of the seizure free patients (55.56%) relapsed with the same seizure types as preoperatively. Although after that, there was only 1 patient relapsed. Of all the seizure types, CC achieved the most favorable seizure outcome in drop attacks. In conclusion, CC could achieve complete seizure remission in a small portion of selected candidates. Exploration of the relapse mechanism will contribute to improve the seizure outcome following CC. |
