STDU was performed to measure the flow velocity, pulsatility index, and diameter of the operated STA before and 14 days after EC-IC bypass. Regional cerebral blood flow (rCBF) and acetazolamide (ACZ) reactivity of the ipsilateral middle cerebral artery (MCA) territory were evaluated by quantitative single-photon emission computed tomography with the ACZ challenge test. We investigated the correlation between STA flow velocity\/diameter and rCBF\/ACZ reactivity in the ipsilateral MCA territory. <i>Results:<\/i> Mean flow velocity (MFV; 26.3 \u00b1 8.8 to 55.3 \u00b1 16.3 cm\/s, p < 0.0001) and diameter (1.57 \u00b1 0.24 to 2.26 \u00b1 0.29 mm, p < 0.0001) of the STA, and rCBF (29.1 \u00b1 3.1 to 35.0 \u00b1 6.4 ml\/100 g\/min, p < 0.0001) and ACZ reactivity (\u20130.02 \u00b1 0.10 to 0.28 \u00b1 0.21, p < 0.0001) of the MCA territory increased after EC-IC bypass compared with the baseline values. STA MFV was significantly correlated with the rCBF 14 days after EC-IC bypass (R = 0.70, p < 0.0001). A cutoff value of postsurgical STA MFV greater than 48.5 cm\/s yielded the highest diagnostic accuracy (sensitivity 86%; specificity, 82%) for rCBF \u226732 ml\/100 g\/min after EC-IC bypass. <i>Conclusions:<\/i> STDU was available for evaluating postsurgical patency of the bypass flow and the rCBF of the ipsilateral MCA territory. The mean blood flow velocity of the operated STA is a highly sensitive parameter for predicting rCBF in the ipsilateral MCA territory after EC-IC bypass.<\/jats:p>","DOI":"10.1159\/000088986","type":"journal-article","created":{"date-parts":[[2005,10,17]],"date-time":"2005-10-17T14:01:44Z","timestamp":1129557704000},"page":"463-469","source":"Crossref","is-referenced-by-count":26,"title":["Superficial Temporal Artery Duplex Ultrasonography for Improved Cerebral Hemodynamics after Extracranial-Intracranial Bypass Surgery"],"prefix":"10.1159","volume":"20","author":[{"given":"Yuko","family":"Hirai","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigeru","family":"Fujimoto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazunori","family":"Toyoda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tooru","family":"Inoue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Uwatoko","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noriko","family":"Makihara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kotaro","family":"Yasumori","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Setsuro","family":"Ibayashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitsuo","family":"Iida","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasushi","family":"Okada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2005,11,23]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1001%2Fjama.280.12.1055"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1136%2Fjnnp.61.1.18"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1056%2FNEJM198511073131904"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.2335%2Fscs.30.97"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1210\/me.2005-0224"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1161%2F01.STR.0000019511.81583.A8"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1056%2FNEJM199108153250701"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097%2F00006123-199701000-00011"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00588221"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016%2FS0022-510X%2802%2900244-7"}],"container-title":["Cerebrovascular Diseases"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/88986","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/88986","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T03:35:08Z","timestamp":1745465708000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000088986"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2005]]},"references-count":10,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2005,11,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000088986","archive":["Portico"],"relation":{},"ISSN":["1015-9770","1421-9786"],"issn-type":[{"value":"1015-9770","type":"print"},{"value":"1421-9786","type":"electronic"}],"subject":[],"published":{"date-parts":[[2005]]}}}
