Endovascular retrieval of a foreign body is becoming an increasingly common procedure in the management of complications resulting from more frequent endovascular procedures. Many procedures are performed on a regular basis in assessment of vascular anatomy, endovascular-guided therapy, and catheter placement. This case report depicts a complication of a chemoport placement resulting in a foreign body. Evaluation of the foreign body raised attention to aberrant anatomy, a persistent left-sided superior vena cava. We further discuss briefly the embryology behind a persistent left-sided superior vena cava, technical errors leading to the foreign body, and assessing the nature of the foreign body through different imaging modalities. This is followed by the subsequent endovascular retrieval by Interventional Radiology and a literature review and individual case assessment of endovascular foreign body retrieval. We discuss considerations for practice based upon our literature review.
血管内取出异物在处理因越来越频繁的血管内手术导致的并发症中已成为一种越来越常见的操作。许多手术定期进行，用于评估血管解剖结构、血管内引导治疗和导管放置。本病例报告描述了化疗端口置入导致异物的并发症。对异物的评估引起了对异常解剖结构——持续存在的左侧上腔静脉的关注。我们进一步简要讨论持续存在的左侧上腔静脉背后的胚胎学、导致异物的技术失误，以及通过不同成像方式评估异物的性质。接下来是介入放射科随后进行的血管内取出，以及血管内异物取出的文献综述和个案评估。我们根据文献综述讨论实践中的注意事项。
