OBJECTIVE: Extracranial @entity1914 are uncommon @entity455 . Even with conservative management complications can arise, such as delayed cerebral @entity887 due to flow-limitation. Though endovascular therapy can be curative, literature demonstrating a preferred technique is scant. Our goal was to evaluate the use of one technique only - the deployment of overlapping self-expandable porous stents - to treat a series of extracranial @entity1914 . METHODS: From 2008 to 2014, 14 consecutive cases of symptomatic extracranial @entity1914 were managed with single or multi-layer porous stents at our institution. Each @entity1 underwent a standardized angiographic follow-up at 6 months. Twelve @entity1 also received a follow-up CT angiogram at 12 months, and yearly thereafter (median radiographic follow-up = 38 months). The total clinical follow-up period ranged between 6 and 69 months (median = 46 months). RESULTS: In our series, each of the extracranial @entity1914 appeared to be the result of carotid artery dissection with associated @entity543 at the origin of every @entity2849 . Endovascular treatment consisted of one to three layers of self-expandable porous stents placed without balloon angioplasty. Immediate post-stenting angiographic images were notable for stagnant opacification of the @entity2849 through the stent(s). All @entity2849 were completely obliterated by the 6-month follow-up angiogram and remained so throughout the radiographic follow-up period. Complications were minimal, consisting of one @entity1 developing a mild post-treatment @entity4820 that resolved during clinical follow-up. CONCLUSION: Extracranial @entity1914 can be successfully obliterated with the use of porous, self-expandable stents alone.
