Persistent hypoglossal artery (PHA), a rare embryological carotid-basilar anastomosis, is usually accompanied by hypoplastic vertebral and posterior communicating arteries, and thereby such vascular anomaly serves as the main feeder supplying the vertebrobasilar territory. Although rarely reported, simultaneous anterior and posterior territory infarcts related to PHA and carotid atherosclerosis can occur. To date, as far as we know, only 4 such cases have been previously reported in the literature. Here, we present the case of a 65-year-old female with a PHA and carotid atherosclerotic plaques, who developed acute multiterritorial infarcts involving the left carotid and vertebrobasilar territories. This case highlights that such a persistent anastomosis should be considered when multiple infarcts involving the anterior and posterior territories are encountered, and should be kept in mind when dealing with carotid atherosclerotic lesion.
永存舌下动脉（PHA）是一种罕见的胚胎期颈动脉-基底动脉吻合，通常伴有椎动脉和后交通动脉发育不全，因此这种血管异常是供应椎基底动脉区域的主要供血血管。虽然相关报道很少，但与PHA和颈动脉粥样硬化相关的前后循环区域同时发生梗死的情况可能会出现。据我们所知，迄今为止，文献中仅先前报道过4例此类病例。在此，我们报告一例65岁女性，患有PHA和颈动脉粥样硬化斑块，发生了累及左侧颈动脉和椎基底动脉区域的急性多区域梗死。该病例强调，当遇到累及前后循环区域的多发梗死时，应考虑到这种持续存在的吻合情况，并且在处理颈动脉粥样硬化病变时应予以重视。
