Patients were divided into two groups based on stent use (DE and BM).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 28 stents were implanted in 24 patients. Of these, 13 were DE and 15 BM. Technical success was achieved in all patients. There were procedure-related complications of retroperitoneal hematoma in some patients (3.6%). The median clinical and imaging follow-up times were 26 and 21\u2005months, respectively, for the BM arm and 13 and 12\u2005months, respectively, for the DE group. The mean stenosis percentage was 80.7\u00b110.9 for the BM group and 87.0\u00b19.5 for the DE group. The mean stent diameter was 4.7\u00b10.5 for the BM group and 3.3\u00b10.4 for the DE group (p&lt;0.0001). There was no statistical difference in the restenosis rates among the two groups, 4\/15 (26.7%) for BM and 4\/13 (30.8%) for DE stents.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Extracranial VAS is a relatively safe procedure. No differences could be elicited in the restenosis rates between BM and DE stents. While VAS has been reported for symptomatic and asymptomatic disease, a benefit of VAS has only been demonstrated for patients with symptoms clearly attributable to the diseased artery. The benefit of stenting in asymptomatic disease or stenting to improve perfusion to the anterior circulation is speculative.<\/jats:p><\/jats:sec>","DOI":"10.1136\/neurintsurg-2011-010051","type":"journal-article","created":{"date-parts":[[2011,6,29]],"date-time":"2011-06-29T01:34:26Z","timestamp":1309311266000},"page":"206-210","source":"Crossref","is-referenced-by-count":32,"title":["Endovascular
