Carotid webs are luminal, shelf-like protrusions at the carotid bulb. Considered to be a variant of fibromuscular dysplasia, carotid webs have been observed principally in African American females. The association between carotid webs and recurrent ischemic strokes continues to be established as patients without traditional stroke risk factors are found to have carotid webs as the only possible cause of symptomatic deficits. The majority of patients undergo endarterectomy; few stent placements are reported. We present the case of an African American female who underwent stent placement for treatment and secondary prevention of stroke attributed to a carotid web. A 33-year-old African American female presented with acute onset left hemiparesis and left facial droop. Alteplase was administered; multiphase head and neck computed tomography angiography revealed an occlusion of the right middle cerebral artery with a web at the carotid bulb. Aspiration catheter thrombectomy achieved a Thrombolysis in Cerebral Infarction (TICI) score of 3. She was placed on 2 antiplatelet agents, and 3 weeks later she underwent stent placement. Follow-up digital subtraction angiography at 3 months showed obliteration of the right carotid artery web and satisfactory integration of the stent into the vessel wall. She was reassessed at 1 year and reported no neurologic symptoms. Although carotid webs are most commonly treated with endarterectomy, they may be amenable to stent therapy with favorable clinical outcomes as shown with this patient.
颈动脉蹼是位于颈动脉球部的管腔内、 shelf 样突出物。颈动脉蹼被认为是纤维肌发育不良的一种变体,主要在非裔美国女性中观察到。随着发现没有传统中风危险因素的患者中颈动脉蹼是症状性缺陷的唯一可能原因,颈动脉蹼与复发性缺血性中风之间的关联仍在不断确立。大多数患者接受了动脉内膜切除术;报道的支架置入病例很少。我们报告了一例非裔美国女性患者,该患者因颈动脉蹼接受了支架置入术以治疗和二级预防中风。一名 33 岁的非裔美国女性出现急性左半身轻瘫和左侧面部下垂。给予了阿替普酶;多期头颈部计算机断层扫描血管造影显示右大脑中动脉闭塞,颈动脉球部有一个蹼。抽吸导管血栓切除术达到了脑梗死溶栓(TICI)3 分。她开始服用 2 种抗血小板药物,3 周后接受了支架置入术。3 个月后的随访数字减影血管造影显示右颈动脉蹼消失,支架与血管壁融合良好。1 年时对她进行了重新评估,她报告没有神经症状。尽管颈动脉蹼最常通过动脉内膜切除术治疗,但它们可能适合支架治疗,如该患者所示,临床结果良好。
