The presumed cause of infarction was large\u2010artery disease (\u2265 50% carotid artery or MCA stenosis or occlusion) in one\u2010third of the patients and cardioembolism in one\u2010fourth of the patients. Half of 230 patients undergoing angiography showed evidence for distal occlusions suggesting artery\u2010to\u2010artery or cardiac emboli. Severe heart disease and potential cardiac sources of embolism were more common in patients with infarcts in the territory of the posterior (inferior) division of MCA than in patients with infarcts in the territory of the anterior (superior) division of MCA. Persisting functional disability on discharge was also more severe in patients with the former than in patients with the latter. The neurological picture was polymorphous and it could sometimes even be misleading, as in some patients with a classical lacunar syndrome or with aphasia and unexpected sparing of speech areas. However, a few clinical syndromes apparently specific for involvement of a single MCA branch could be delineated, and in some instances they were highly predictive of embolism from heart or proximal artery.<\/jats:p>","DOI":"10.1002\/ana.410250605","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T14:12:06Z","timestamp":1104588726000},"page":"555-560","source":"Crossref","is-referenced-by-count":38,"title":["Middle cerebral artery pial territory infarcts: A study of the lausanne stroke registry"],"prefix":"10.1002","volume":"25","author":[{"given":"Julien","family":"Bogousslavsky","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guy","family":"van Melle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Franco","family":"Regli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,10,8]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1968.00480030026002"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/92.4.897"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.17.1.69"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.14.6.867"},{"key":"e_1_2_1_6_2","first-page":"13","article-title":"Obstructions de la carotide interne et ramollissements c\u00e9r\u00e9braux.
