Q & A with Dr. David Zielske
Question: WADA Testing
I need help coding a portion of a case, super-selective WADA testing of anterior spinal artery using sodium Amytal and lidocaine with SSEP and neuralphysiological monitoring. Microcath was passed into the anterior spinal artery to a point just proximal to the AV fistula. First testing was performed with the infusion of 25 mg of sodium Amytal from this site. Monitoring did not show any evidence of changes in the lower extremity or anal sphincter monitoring.
