Intravascular foreign bodies are a known complication of medical and dental procedures. Dental anesthetic needles may be broken off and retained in the oropharynx. These needles have occasionally been reported to migrate through the oral mucosa in to deeper structures. Here we present the case of a 57-year-old man who had a retained dental needle that had migrated into his internal carotid artery. The needle was removed using endovascular techniques. To our knowledge, this is the first report of a retained dental needle being retrieved using this method. We review the literature on intravascular foreign bodies, retained dental needles, and endovascular techniques for retrieval of such foreign bodies.
血管内异物是医疗和牙科手术中已知的并发症。牙科麻醉针可能会折断并留在口咽中。这些针偶尔会被报道穿过口腔黏膜迁移到更深的结构中。在此，我们报告一例57岁男性病例，其体内有一根滞留的牙科针已迁移至颈内动脉。通过血管内技术取出了该针。据我们所知，这是首次报道使用这种方法取出滞留的牙科针。我们回顾了有关血管内异物、滞留牙科针以及用于取出此类异物的血管内技术的文献。
