Based on clinical features and computed tomographic findings, patients were classified as having lacunar infarcts (n = 61), nonlacunar infarcts (n = 53), and infarcts of indeterminate type (n = 8). Severe carotid bifurcation disease (greater than or equal to 50% stenosis or occlusion) was significantly more common in nonlacunar than in lacunar infarcts, on both the ipsilateral (p less than 0.001) and the contralateral (p less than 0.01) sides; 79% of the patients with nonlacunar infarcts had severe carotid bifurcation and\/or middle cerebral artery disease on the ipsilateral side compared with 3.3% of the patients with lacunar infarcts. Our data underscore the need for classification of patients by the underlying mechanisms in future studies of treatment of ischemic stroke.<\/jats:p>","DOI":"10.1161\/01.str.20.1.59","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T20:08:03Z","timestamp":1308341283000},"page":"59-64","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":37,"title":["Clinical and radiologic features of lacunar versus nonlacunar minor stroke."],"prefix":"10.1161","volume":"20","author":[{"given":"B","family":"Norrving","sequence":"first","affiliation":[{"name":"Department of Neurology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S","family":"Cronqvist","sequence":"additional","affiliation":[{"name":"Department of Neurology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","container-title":["Stroke"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ahajournals.org\/doi\/pdf\/10.1161\/01.STR.20.1.59","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T21:24:39Z","timestamp":1715549079000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.STR.20.1.59"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1989,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1989,1]]}},"alternative-id":["10.1161\/01.STR.20.1.59"],"URL":"https:\/\/doi.org\/10.1161\/01.str.20.1.59","relation":{},"ISSN":["0039-2499","1524-4628"],"issn-type":[{"value":"0039-2499","type":"print"},{"value":"1524-4628","type":"electronic"}],"subject":[],"published":{"date-parts":[[1989,1]]},"assertion":[{"value":"1989-01-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
