How many patients have undergone bilateral surgery, and what have been the results?
Of the pediatric patients with moyamoya disease operated on as of March 1, 2008, 167 patients have undergone synangiosis on both sides of the head under the same anesthetic and using EEG monitoring. We have had to stop the operation after the first side was completed in 19 patients because of monitoring changes or other technical concerns, and the surgery was completed later safely in all of these. Depending on the patient’s status and the reasons for stopping the surgery, the opposite side will be done in a period ranging from several days to three months from following the first operation. In certain patients, we recommend from the start that surgery be carried pit on one side at a time for clinical and/or technical reasons.
