Abstract

A modified provocative test to assess the safety of embolization of cerebral and spinal arteriovenous malformations is described. The modified test uses successive amobarbital and lidocaine injections to elicit any possible neurological deficitboth mixed with radiopaque material to visualize the distribu tion of the anesthetic in the vessels. The modified provocative test caused no false negative results in 11 patients tested compared to six of 27 patients with the unmodified method.
