Persistent stapedial artery is a vascular anomaly with both clinical and surgical implications. Because of its scarcity, however, it remains underrecognized on imaging. Presented here is a series of 10 cases, demonstrating characteristic CT findings associated with this vascular anomaly and its most common pathognomonic imaging signs. The variable morphologic configurations and their corresponding embryologic underpinnings are described. Clinical and surgical implications of this rare anomaly are discussed.
永存镫骨动脉是一种具有临床和手术意义的血管异常。然而，由于其罕见性，在影像学上仍然认识不足。本文介绍了一系列 10 例病例，展示了与这种血管异常及其最常见的特征性影像学征象相关的特征性 CT 表现。描述了其可变的形态结构及其相应的胚胎学基础。讨论了这种罕见异常的临床和手术意义。
