The incidence of epilepsy after ventricular shunting procedures.
One hundred eighty of 207 consecutive patients with ventricular shunts were studied to determine the incidence of post-shunt epilepsy. Of these 17 (9.4%) developed seizures. The incidence fell from 15.2% in children younger than 1 year to 6.9% in patients over 50 years of age, but age was not statistically significant. Of patients with a parietal ventricular catheterization site only 6.6% had convulsions, in contrast to 54.5% of those with a frontal locus. The incidence of seizures rose with multiple ventricular catheter revisions, but was unrelated to bilaterality of shunting. The risk of seizures fell from 5% in the 1st year after shunting to 1.1% after the 3rd year.
