The Doppler examination showed that the resistive index (RI) of the common carotid artery (CCA) and ICA was higher but the peak systolic velocity was lower on the diseased side as compared with the normal side. Absence of the diastolic phase was found in the CCA flow in 2 cases and in the ICA flow in 3 cases on the diseased side. The mean CCA flow volume on the diseased side (271\u00b182 mL\/min) was half or less than that on the normal side (680\u00b186 mL\/min) (P &lt; 0.01). The flow volume of the diseased ICA (49\u00b120 mL\/min) was markedly lower than that of the normal side (344\u00b149 mL\/min) (P &lt; 0.01) and was also less than that of the ipsilateral external carotid artery (ECA) (129\u00b143 mL\/min). The Doppler ophthalmic artery flow all showed a forward direction.<\/jats:p>\n                  <jats:p>The authors propose that the following extracranial carotid ultrasono graphic findings may be helpful in the prediction of intracranial carotid artery occlusion: (1) diminished frequencies, increased RI, and a more than 50% re duction of flow volume in the CCA as compared with the opposite side; (2) diminished frequencies to loss of the diastolic phase, a more than 50% reduction of the flow volume, and reversed ICA\/ECA flow volume in the ICA as com pared with the opposite side; and (3) a forward Doppler ophthalmic artery flow.<\/jats:p>","DOI":"10.1177\/000331979304400803","type":"journal-article","created":{"date-parts":[[2008,7,28]],"date-time":"2008-07-28T17:57:07Z","timestamp":1217267827000},"page":"607-613","source":"Crossref","is-referenced-by-count":9,"title":["Carotid Ultrasonographic Findings in Intracranial Internal Carotid Artery Occlusion"],"prefix":"10.1177","volume":"44","author":[{"given":"Tsong-Hai","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Neurology, Chang Gung Memorial Hospital, Taipei, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shan-Jin","family":"Ryu","sequence":"additional","affiliation":[{"name":"Department of Neurology, Chang Gung Memorial Hospital, Taipei, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sien-Tsong","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Neurology, Chang Gung Memorial Hospital, Taipei, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin-Lieh","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Neurology, Chang Gung Memorial Hospital, Taipei, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1993,8,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.16.6.945"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-198803000-00015"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.20.1.123"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.20.5.612"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1016\/0741-5214(87)90219-9"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1177\/000331978503600103"},{"key":"atypb7","first-page":"74","volume":"8","author":"Pierce GE","year":"1988","journal-title":"J Vasc Surg"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1161\/str.18.3.686a"},{"key":"atypb9","first-page":"575","volume":"91","author":"Lee TH","year":"1992","journal-title":"J Formosan Med Assoc"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.9.4.360"},{"key":"atypb11","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.13.3.392"},{"key":"atypb12","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.20.1.1"},{"key":"atypb13","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.12.6.793"},{"key":"atypb14","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.16.6.969"},{"key":"atypb15","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.7.4.370"},{"key":"atypb16","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.14.2.256"},{"key":"atypb17","doi-asserted-by":"publisher","DOI":"10.1007\/978-94-009-4305-6_7"},{"key":"atypb18","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.22.3.319"},{"key":"atypb19","first-page":"41","volume":"6","author":"Pfeifer JS","year":"1982","journal-title":"Bruit"},{"key":"atypb20","doi-asserted-by":"publisher","DOI":"10.1007\/BF00333434"},{"key":"atypb21","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410280507"}],"container-title":["Angiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/000331979304400803","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/000331979304400803","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T10:15:25Z","timestamp":1777371325000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/000331979304400803"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1993,8]]},"references-count":21,"journal-issue":{"issue":"8","published-print":{"date-parts":[[1993,8]]}},"alternative-id":["10.1177\/000331979304400803"],"URL":"https:\/\/doi.org\/10.1177\/000331979304400803","relation":{},"ISSN":["0003-3197","1940-1574"],"issn-type":[{"value":"0003-3197","type":"print"},{"value":"1940-1574","type":"electronic"}],"subject":[],"published":{"date-parts":[[1993,8]]}}}
