We conducted A\/S in 20 high-risk patients (15 males, 5 females, mean age = 64.5 years, range = 49\u201383 years) with symptomatic (n = 16) and asymptomatic (n = 4) high-grade stenosis (&gt;70%, NASCET criterion) of the internal carotid artery. Patients had neurological examinations before, during and after the procedure. Color-coded duplex sonography was performed before and 24\u00a0h and every 3 months after the procedure; the 3-month examination also included cerebral angiography. The mean degree of stenosis was reduced from 85.75 \u00b1 7.47 to 8.0 \u00b1 22.09% in angiography. In an 18-month follow-up with color-coded duplex sonography the effects of the A\/S could be visualized effectively: 2 with local, transient vasospasms, 1 with asymptomatic occlusion, 2 carotid arteries with remaining stenosis of 50% and 2 with minimal hyperplasia within the stent. In conclusion, in patients with a high perioperative risk, A\/S is a therapeutic alternative to surgery.<\/jats:p>","DOI":"10.1159\/000016024","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T15:43:24Z","timestamp":1050421404000},"page":"44-48","source":"Crossref","is-referenced-by-count":13,"title":["Carotid Artery Stenting in Patients at Surgical High Risk: Clinical and Ultrasound Findings"],"prefix":"10.1159","volume":"10","author":[{"given":"B.","family":"Griewing","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Brassel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"U.","family":"von Smekal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.T.","family":"Al Ahmar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ch.","family":"Kessler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2000,1,7]]},"container-title":["Cerebrovascular Diseases"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/16024","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/16024","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T04:39:05Z","timestamp":1745469545000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000016024"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2000,2,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000016024","archive":["Portico"],"relation":{},"ISSN":["1015-9770","1421-9786"],"issn-type":[{"value":"1015-9770","type":"print"},{"value":"1421-9786","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000]]}}}
