摘要

Introduction: For patients with refractory epilepsy patients, the sub-group characterized for seizures involving falls or drop-attack, the technique of callosotomy, as a palliative measure hasbeen validated and used to control this type of seizures. Method: Group of 16 patients operatedduring period of four years, evaluated by protocol, which was performed as a palliative callosotomycrisis management technique was evaluated. Results: The observed group, 10 were males and6 females, mean age 30 years, range between 19-46 years. Average evolution of epilepsy in 20.8years, 14 cases crisis was starting before age 14. Major crises were TCG (generalized tonic clonic)and a tonic seizures were being 62.5% daily and 37.5% monthly, 100% had a history of TEC(brain trauma) and 56% history of status epilepticus. Was performed anterior callosotomy twothirds in 8 patients (mean follow-up 23.8 months), 6 patients complete callosotomy (averagefollow-up 15.5 months), and in 2 cases, two anterior thirds and then total callosotomy (1 case22 months, and another 1 month follow-up). Seizures management fall > 50% in 75% ofpatients (3 cases without seizures of fall with anterior callosotomy two thirds), and for completecallosotomy, 100% control crisis in > 80% of patients (3 cases without seizures of fall was foundin this group). Conclusion: The technique callosotomy as a palliative measure in the context ofdrop-attack or crises involving falls, in our experience with adult patients, has been a good toolin controlling this type of seizures.
