Authors experienced an anesthesia for aortorenal shunt operation for renovascular hypertension caused by atherosclerosis in a 38-year-old male. Tracheal topical anesthesia with 4% lidocaine was performed prior to induction of anesthesia with intravenous thiopental sodium and nitrous oxide-oxygen by mask. Semiclosed circle system with nitrous oxide-oxygen-halothane was used in the maintenance of anesthesia. Blood pressure and pulse rate were increased during manipulation of perirenal tissues in spite of administration of high concentration of halothane with nitrous oxide-oxygen and controlled respiration under positive pressure.
