Provocative Testing

The use of provocative testing is controversial, with many, particularly European, authorities believing it to be unnecessary. However, other, particularly American, authorities consider it useful. I personally perform provocative testing when embolizing AVMs in eloquent areas such as primary motor cortex, language cortex and occipital cortex [25].

With the catheter in a satisfactory position for potential embolization, 40-50 mg of sodium amytal is injected. If a temporary deficit occurs, embolization is not performed. A positive test indicates normal cortex has been perfused. The test remains controversial and many find the anatomical information as good as the physiological from provocative testing.
