Giant serpentine aneurysms (GSAs) form a specific subgroup of giant cerebral aneurysms that have pathognomonic angiographic features. We report the angiographic findings of a GSA demonstrating a striking convoluted dynamic flow pattern, which we have called the 'pretzel sign'. The aneurysm was successfully treated by permanent occlusion of the parent vessel using a detachable balloon. GSAs should be identified prior to treatment in view of their particular management requirements.
巨大蜿蜒状动脉瘤（GSAs）构成了具有特征性血管造影表现的巨大脑动脉瘤的一个特定亚组。我们报告了一例GSA的血管造影结果，其显示出一种显著的盘绕状动态血流模式，我们将其称为“椒盐卷饼征”。该动脉瘤通过使用可脱性球囊永久性闭塞载瘤血管而成功治疗。鉴于其特殊的治疗要求，GSAs应在治疗前予以识别。
