Cerebral angiography is performed for diagnosis and management of
moyamoya disease and in childhood
moyamoya disease is usually carried out under
general anesthesia after tracheal intubation. Mechanical irritation to trachea resulting in
pain,
cough,and increase in secretion after termination of the
general anesthesia sometimes occurs and it sometimes causes
hyperventilation resulting in hypocapnea. Continuous hypocapnea sometimes causes appearance of ischemic attacks in
moyamoya disease. In the present study, we examine cerebral angiography conducted under
general anesthesia using face mask ventilation in fourteen children with
moyamoya disease.
Sevoflurane was used as
inhalation anesthetics. Face mask
anesthesia was sixteen times in total in the 14 patients. Cerebral angiography terminated uneventfully in these patients except one patient who showed
bronchospasm after induction of
anesthesia and required tracheal intubation. However, the patient showed uneventful course after termination of the angiography. Tracheal irritation did not appear and all the patients were asleep just after termination of face mask
anesthesia except for the patient who required tracheal intubation. In the latter case, the patient frequently coughed out phlegm after
general anesthesia with tracheal intubation. In conclusion,
general anesthesia with face mask ventilation was thought to be one of the suitable
anesthetic methods introduced for cerebral angiography in childhood
moyamoya disease.
