Carotid webs are intraluminal filling defects at the carotid bulb which are considered rare, though possibly underappreciated entities with recent studies demonstrating a likely casual association with ischemic stroke. The purpose of the study is to describe our recent experience with clinical and imaging manifestations of carotid webs.
A retrospective review of CTA neck studies in all adult patients presenting to our institution during the 19-month study interval was performed to determine the presence of carotid webs. Subsequent chart review of these patients with webs was performed to assess their clinical history and to obtain demographic detail.
A total of 14 patients were identified with carotid webs in the study population. The mean age of patients with webs was 42.1 years (range: 28-54), consisting mostly of African Americans (86%) and females (64%). Ten (71%) of web patients had a history of ischemic stroke, each ipsilateral to the side of web, and at least four of these patients had recurrent ischemic stroke.
We provide one of the largest sample sizes of webs gathered in a single study. Given its association with ischemic stroke, carotid webs should be assessed for in all patients presenting with ischemic stroke, especially younger African Americans.
颈动脉窦是颈动脉球部的腔内充盈缺损，被认为是一种罕见的，但可能被低估的实体，最近的研究表明，它与缺血性卒中可能存在偶然关联。本研究旨在描述我们最近在颈动脉窦的临床和影像学表现方面的经验。
对在 19 个月的研究期间就诊于我院的所有成年患者的 CTA 颈部研究进行了回顾性分析，以确定是否存在颈动脉窦。对这些存在颈动脉窦的患者进行后续的图表回顾，以评估其临床病史并获取人口统计学细节。
在研究人群中，共发现 14 例颈动脉窦患者。有颈动脉窦的患者的平均年龄为 42.1 岁（范围：28-54 岁），主要为非裔美国人（86%）和女性（64%）。10 例（71%）颈动脉窦患者有缺血性卒中病史，每个患者均同侧于颈动脉窦的一侧，其中至少 4 例患者有复发性缺血性卒中。
我们提供了在单一研究中收集到的最大的颈动脉窦样本量之一。鉴于其与缺血性卒中的关联，应在所有出现缺血性卒中的患者中评估颈动脉窦，尤其是年轻的非裔美国人。
