The intravascular embolization of catheter fragments is an uncommon yet potentially serious complication of central venous catheters (CVC). We present the case of an 81-year-old female with a history of endometrial cancer who presented from an oncologic appointment with a nonfunctioning chest port (CVC). The chest port was placed 10 months prior without complication. An initial fluoroscopic image of the chest revealed detachment and migration of the catheter towards the right atrium. The catheter was successfully retrieved with a gooseneck snare using an inferior approach through the femoral vein. Catheter detachment and embolization is a rare complication of CVCs that should be included in the differential of a nonfunctional port.
导管碎片的血管内栓塞是中心静脉导管（CVC）一种罕见但可能严重的并发症。我们报告了一例81岁有子宫内膜癌病史的女性患者，她在一次肿瘤门诊就诊时发现胸部端口（CVC）无法正常使用。该胸部端口于10个月前放置，当时无并发症。胸部的初始荧光透视图像显示导管分离并向右心房迁移。通过股静脉采用下腔途径，使用鹅颈圈套器成功取出了导管。导管分离和栓塞是CVC的一种罕见并发症，在鉴别无功能端口时应予以考虑。
