Pre- and Postoperative Measurements of rCBF in Intracranial Arteriovenous Malformations

Using Xenon inhalation method, the authers measured the rCBF's within 24 hours before and after the operation of 4 AVM patients. We found the obliteration of the cerebral steal syndrome in all cases and the loss of initial shunt peak in 2 cases after excision of AVM. We discussed these hemodynamic changes in AVM and reviewed the literatures.
