Serial brain single-photon emission computed tomography (SPECT) was performed on 25 patients before surgery and on the third and tenth postoperative days. The hemispheric perfusion on SPECT was calculated semi-quantitatively using statistical parametric mapping and a probabilistic brain atlas. <i>Results:<\/i> Among 120 procedures, there were 4 permanent postoperative neurological deficits (3.3%) and 20 postoperative transient neurologic deteriorations with unknown etiology (17%). In 25 patients analyzed for postoperative perfusion changes, cerebral perfusion increased on the third postoperative day and the increased perfusion negatively correlated with preoperative perfusion (correlation coefficient = \u20130.77; p < 0.001). Temporal changes and the location of transient hyperperfusion on SPECT correlated with the time course and neurological deficits associated with postoperative transient neurological deterioration in 3 patients. <i>Conclusions:<\/i> Postoperative transient relative hyperperfusion is a common phenomenon and may be one of the causes of postoperative transient neurological deterioration after STA-MCA bypass surgery for ischemic cerebral diseases.<\/jats:p>","DOI":"10.1159\/000132205","type":"journal-article","created":{"date-parts":[[2008,5,16]],"date-time":"2008-05-16T08:10:54Z","timestamp":1210925454000},"page":"580-586","source":"Crossref","is-referenced-by-count":115,"title":["Transient Hyperperfusion after Superficial Temporal Artery\/Middle Cerebral Artery Bypass Surgery as a Possible Cause of Postoperative Transient Neurological Deterioration"],"prefix":"10.1159","volume":"25","author":[{"given":"Jeong Eun","family":"Kim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang Wan","family":"Oh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"O-Ki","family":"Kwon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sukh Que","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang Eun","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu Kyeong","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2008,5,16]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1227%2F00006123-198408000-00006"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.3171%2Fjns.2004.100.1.0128"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.2176%2Fnmc.34.15"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1227%2F01.NEU.0000124754.84425.48"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1097%2F00006123-198907000-00015"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016%2FS0090-3019%2897%2990106-3"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.jacc.2003.12.039"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1067%2Fmva.2003.231"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1038%2Fsj.jcbfm.9600244"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1159%2F000089364"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1161%2F01.STR.0000068781.31429.BE"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.3171%2Fjns.2003.99.3.0504"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1227%2F00006123-198610000-00028"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1227%2F01.NEU.0000159719.47528.2E"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1159%2F000093452"}],"container-title":["Cerebrovascular Diseases"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/132205","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/132205","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T21:20:50Z","timestamp":1745443250000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000132205"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008]]},"references-count":15,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2008,6,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000132205","archive":["Portico"],"relation":{},"ISSN":["1015-9770","1421-9786"],"issn-type":[{"value":"1015-9770","type":"print"},{"value":"1421-9786","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008]]}}}
