Abstract:
Objective To explore the imaging characteristics of hemiplegic patients with intractable epilepsy before and after modified hemispherectomy and their clinical significances.Methods The clinical data of 29 patients,admitted to and underwent hemispherectomy in our hospital from 1996 to 2010,were retrospectively analyzed.The characteristics ofpre-and post-surgical imaging of these patients were analyzed.Results Pre-surgical imaging showed that the crus cerebri of healthy lateral was enlarged for compensation and another lateral was atrophy with illed hemisphere.Hemispherectomy succeed in all the patients on the illed hemisphere; post-surgical imaging showed that operative cavity was reduced through healthy hemisphere shiftting to operative lateral,frontal sinus enlarging and skull becoming thickness.Follow-up was performed for 2-15 years; the disturbance of the nervous function was not worsened and there was no late complication in all the patients; Engel grading showed grade Ⅰ and Ⅱin 93.1％ patients and grade Ⅲ in 6.9％.Conclusion The CT/MR imaging is more valuable in localizing of the lesions as compared with EEG; the imaging changes before and after hemispherectomy can explain the shrunk cacity and few late complications.
