We aimed to assess the etiologies and stroke pattern of PCA territory infarction in a Korean population. <i>Method:<\/i> We reviewed consecutive patients with acute PCA territory infarction who underwent diffusion-weighted MRI (DWI) and magnetic resonance angiography (MRA) within 7 days after onset. <i>Results:<\/i> A total of 205 patients (male 56%, mean age 65.4 \u00b1 12.4 years) were recruited. \u2018Superficial\u2019, \u2018deep\u2019 and \u2018superficial plus deep\u2019 infarcts accounted for 26.3, 47.8 and 25.9% of infarcts, respectively. There were 126 patients who had infarcts limited to the PCA territory, whereas 79 patients had concomitant infarcts in other territories. Large artery atherosclerosis (LAA, 42.4%) was the most frequent etiology, followed by cardiogenic embolism (20%), small-vessel occlusion (20%), undetermined (18%) and other determined (3%) etiology. Among the 87 patients with LAA, 38 had intrinsic PCA disease without atherosclerosis in the proximal vessels. In these patients, stroke mechanisms included atheromatous branch occlusion (n = 19), in situ thrombotic occlusion (n = 11) and artery-to-artery embolism (n = 8). While the occipital area was the most frequently involved in general, the ventrolateral thalamic area was more frequently involved than the occipital area in patients with intrinsic PCA atherosclerotic disease. <i>Conclusion:<\/i> The patterns of PCA territory infarction are different according to underlying etiologies. In our population, intrinsic atherosclerotic disease is a relatively important cause of PCA territory infarction that produces strokes through a variety of mechanisms.<\/jats:p>","DOI":"10.1159\/000229016","type":"journal-article","created":{"date-parts":[[2009,7,20]],"date-time":"2009-07-20T11:58:19Z","timestamp":1248091099000},"page":"298-305","source":"Crossref","is-referenced-by-count":44,"title":["Posterior Cerebral Artery Infarction: Diffusion-Weighted MRI Analysis of 205 Patients"],"prefix":"10.1159","volume":"28","author":[{"given":"Eugene","family":"Lee","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong-Wha","family":"Kang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sun U.","family":"Kwon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jong S.","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,7,21]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00415-002-0742-0"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1007%2Fs004150050146"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1468-1331.2003.00750.x"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1002%2Fana.410210311"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1001%2Farchneur.1988.00520330037008"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1212%2F01.WNL.0000163768.58168.3A"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1001%2Farchneur.56.7.824"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1159%2F000016053"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1161%2F01.STR.17.4.648"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1212%2FWNL.47.5.1125"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1159%2F000008090"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1080%2F02841850500216004"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.jacc.2004.05.075"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1161%2F01.STR.24.1.35"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1212%2FWNL.21.9.900"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1212%2FWNL.39.9.1246"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.3988%2Fjcn.2005.1.1.1"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1161%2F01.STR.0000189999.19948.14"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1212%2F01.wnl.0000314686.94007.d0"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1468-1331.2003.00750.x"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.3988%2Fjcn.2006.2.4.225"}],"container-title":["Cerebrovascular Diseases"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/229016","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/229016","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T21:47:51Z","timestamp":1745444871000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000229016"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":21,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2009,8,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000229016","archive":["Portico"],"relation":{},"ISSN":["1015-9770","1421-9786"],"issn-type":[{"value":"1015-9770","type":"print"},{"value":"1421-9786","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009]]}}}
