However, the optimal procedure has not yet been determined. This study compared the efficacy of performing bifrontal encephalogaleosynangiosis (EGS) using a craniotomy with performing EGS using bur holes.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>The authors retrospectively analyzed surgical results of pediatric patients with moyamoya disease treated using encephaloduroarteriosynangiosis (EDAS) and bifrontal EGS with a craniotomy, or EGS with bur holes, for the purpose of improving the ischemia of the ACA territory. Patients' demographic data, clinical presentations, surgical therapies, and clinical outcomes were reviewed.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>Nine patients underwent EDAS with bifrontal EGS using a craniotomy. Three patients underwent EDAS with EGS using bur holes for 5 cerebral hemispheres (1 bur hole in 2 hemispheres, 2 bur holes in 2 hemispheres, and 3 bur holes in 1 hemisphere). The mean follow-up period was 46.8 months (range 7\u201396 months). Preoperative symptoms improved in all patients in each group. The collateral circulation in the ACA territory made by EGS was divided into 3 groups according to postoperative angiography results: Group A (revascularization of more than two-thirds of the ACA territory), Group B (revascularization between one-third and two-thirds), and Group C (revascularization less than one-third). Of 5 hemispheres treated with EGS using bur holes, 1 was evaluated as Group B and 4 as Group C. Of 18 hemispheres treated with bifrontal EGS using a craniotomy, 8 were evaluated as Group A, 7 as Group B, and 3 as Group C. The patients who underwent bifrontal EGS using a craniotomy showed significantly better revascularization than those who underwent EGS using bur holes (p = 0.0065). Cerebral blood flow in the ACA territory improved in 13 (92.9%) of 14 hemispheres in patients treated with bifrontal EGS. In contrast, only 3 (60%) of 5 hemispheres demonstrated an increase of CBF in patients treated with EGS using bur holes. A trend was demonstrated for better improvement with bifrontal EGS (p = 0.08).<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Encephaloduroarteriosynangiosis with bifrontal EGS using a craniotomy demonstrated better revascularization and improvement of CBF in the ACA territory than with EGS using bur holes. Bifrontal EGS using a craniotomy is considered to be a simple, safe, and effective surgical procedure for improvement of the ischemia of the ACA territory in pediatric patients with moyamoya disease.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2012.6.peds11483","type":"journal-article","created":{"date-parts":[[2012,7,21]],"date-time":"2012-07-21T00:19:34Z","timestamp":1342829974000},"page":"246-251","source":"Crossref","is-referenced-by-count":17,"title":["Bifrontal encephalogaleosynangiosis for children with moyamoya disease"],"prefix":"10.3171","volume":"10","author":[{"given":"Hideki","family":"Ogiwara","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobuhito","family":"Morota","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-peds11483","series-title":"J Neurosurg Pediatr","doi-asserted-by":"publisher","first-page":"73","DOI":"10.3171\/2010.4.PEDS09478","article-title":"Postoperative neurological deterioration in pediatric moyamoya disease: watershed shift and hyperperfusion.
