Careful review of the late films of their initial arteriographic series or repeat arteriography with a specialized technique revealed a thin trickle of contrast medium flowing antegrade through a region of extreme stenosis. This thin line of contrast material ascended slowly to meet the column of contrast medium in the cavernous carotid segment that was filling by collateral circulation. Surgical exploration of the neck in these patients revealed a patent but collapsed ICA distal to a localized atheromatous plaque. These patients have been asymptomatic following carotid endarterectomy. This distinctive angiographic appearance may be described as \u201catheromatous pseudo-occlusion.\u201d Once recognized, carotid endarterectomy is the logical treatment of choice.<\/jats:p>","DOI":"10.3171\/jns.1980.52.6.0782","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:42:58Z","timestamp":1241710978000},"page":"782-789","source":"Crossref","is-referenced-by-count":48,"title":["Atheromatous pseudo-occlusion of the internal carotid artery"],"prefix":"10.3171","volume":"52","author":[{"given":"Laligam N.","family":"Sekhar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto C.","family":"Heros","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Preston R.","family":"Lotz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arthur E.","family":"Rosenbaum","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Neurology","doi-asserted-by":"publisher","first-page":"769","DOI":"10.1212\/WNL.28.8.769","article-title":"Delayed cerebral ischemic episodes distal to occlusion of major cerebral arteries.","volume":"28","author":"Barnett","year":"1978"},{"key":"b2","series-title":"Stroke","doi-asserted-by":"publisher","first-page":"448","DOI":"10.1161\/01.STR.9.5.448","article-title":"\u201cStump\u201d of the internal carotid artery \u2014 a source for further cerebral embolic ischemia.","volume":"9","author":"Barnett","year":"1978"},{"key":"b3","series-title":"Arch Surg","doi-asserted-by":"publisher","first-page":"604","DOI":"10.1001\/archsurg.1971.01350060068022","article-title":"Radiographically occluded, anatomically patent carotid arteries.","volume":"102","author":"Clark","year":"1971"},{"key":"b4","series-title":"South Med J","doi-asserted-by":"publisher","first-page":"904","DOI":"10.1097\/00007611-197708000-00003","article-title":"Importance of the external carotid artery in extracranial cerebrovascular occlusive disease.","volume":"70","author":"Clayson","year":"1977"},{"key":"b5","series-title":"Stroke","doi-asserted-by":"publisher","first-page":"450","DOI":"10.1161\/01.STR.10.4.450","article-title":"External carotid artery in internal carotid artery occlusion.
