Long-term follow-up after callosotomy--a prospective, population based, observational study.

ABSTRACT:

Objective

Analyze the long-term outcome of callosotomies with regard to seizure types and frequencies and antiepileptic drug treatment.

Methods

This longitudinal observational study is based on data from the prospective Swedish National Epilepsy Surgery Register. Thirty-one patients had undergone callosotomy in Sweden 1995-2007 and had been followed for 2 and 5 or 10 years after surgery. Data on their seizure types and frequencies, associated impairments, and use of antiepileptic drugs have been analyzed.

Results

The median total number of seizures per patient and month was reduced from 195 before surgery to 110 two years after surgery and 90 at the long-term follow-up (5 or 10 years). The corresponding figures for drop attacks (tonic or atonic) were 190 before surger
