In the preoperative studies, CBF in the region of the posterior fossa was low and the oxygen extraction fraction (OEF) was high, the so-called \u201cmisery perfusion syndrome.\u201d Such changes were evident in both the posterior circulation and the anterior circulation regions. Postoperatively, there was a significant increase in CBF, a significant decrease in the OEF not only in the region of posterior circulation but also over the entire brain, and a disappearance of the uncoupling between CBF and oxygen metabolism. The STA-SCA bypass procedure is effective in improving CBF and metabolism in patients with vertebrobasilar occlusive disease.<\/jats:p>","DOI":"10.3171\/jns.1992.76.6.0955","type":"journal-article","created":{"date-parts":[[2009,5,27]],"date-time":"2009-05-27T02:57:08Z","timestamp":1243393028000},"page":"955-960","source":"Crossref","is-referenced-by-count":24,"title":["Cerebral blood flow and metabolism following superficial temporal artery to superior cerebellar artery bypass for vertebrobasilar occlusive disease"],"prefix":"10.3171","volume":"76","author":[{"given":"Akira","family":"Ogawa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Motonobu","family":"Kameyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenji","family":"Muraishi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Yoshimoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masatoshi","family":"Ito","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiharu","family":"Sakurai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Stroke","doi-asserted-by":"publisher","first-page":"383","DOI":"10.1161\/01.STR.8.3.383","article-title":"Basilar artery occlusion.
