This study attempts to clarify the pathogenesis of LA by testing the hypothesis that increased frequency of LA with occlusive extra\u2010cranial arterial disease results directly from global reduction in cerebral blood flow (CBF). Thirty\u2010five normal subjects and 55 patients with carotid stenosis (&gt;70%) were studied using MR. CBF was measured using phase contrast MR angiography and LA was scored using previously validated scoring system. Patients were divided into those with evidence of previous infarction on MRI and those without. LA was more severe in patients than in normal subjects (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.01) and correlated with age in normal subjects but not in patients. CBF in patients with (809\u2003\u00b1\u2003214\u2003ml\/min) and without infarction (mean 792\u2003\u00b1\u2003181\u2003ml\/min) was significantly lower than in normal subjects (mean 1073\u2003\u00b1\u2003194\u2003ml\/min). There was no correlation between the severity of LA and measured CBF in any group. The severity of LA is greater in patients with severe carotid stenosis but is not correlated to reductions in CBF. This suggests that microvascular abnormality is the dominant pathogenetic factor in LA even in the presence of severe stenotic\/occlusive large vessel disease.<\/jats:p>","DOI":"10.1111\/j.1468-1331.2006.01115.x","type":"journal-article","created":{"date-parts":[[2006,1,12]],"date-time":"2006-01-12T13:33:46Z","timestamp":1137072826000},"page":"10-16","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Relationship of deep white matter hyperintensities and cerebral blood flow in severe carotid artery stenosis"],"prefix":"10.1111","volume":"13","author":[{"given":"T.","family":"Patankar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Widjaja","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Chant","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"McCollum","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Baldwin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Jeffries","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Sutcliffe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Burns","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Jackson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,1,12]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0317167100037264"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.26.7.1293"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1972.00490150037007"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.22.10.1094"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.30.9.920"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410190306"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1990.00530020061017"},{"key":"e_1_2_6_9_2","first-page":"273","article-title":"Leukoaraiosis: correlation of MR and CT findings with blood flow, atrophy, and cognition","volume":"11","author":"Kobari M","year":"1990","journal-title":"AJNR.
