Totally implantable venous access devices (TIVADs) are commonly used for prolonged intravenous treatment, particularly in oncology. Although removal is typically a straightforward procedure at the end of treatment, it can occasionally be complicated by adhesion of the distal end of the catheter to the intravascular wall. This rare complication is often associated with factors such as prolonged catheter dwell time, use of polyurethane material, and younger age at insertion. The technique used for removal depends largely on the degree of adhesion. We report the case of a 60-year-old woman with a TIVAD in place for 12 years for chemotherapy for breast cancer. Removal was challenging due to distal adhesion of the catheter but was ultimately successful following careful dissection and traction.
完全植入式静脉通路装置（TIVADs）常用于长期静脉治疗，尤其是在肿瘤学领域。尽管在治疗结束时移除通常是一个简单的过程，但偶尔可能会因导管远端与血管壁粘连而变得复杂。这种罕见的并发症通常与导管留置时间延长、聚氨酯材料的使用以及插入时年龄较小等因素有关。移除所采用的技术很大程度上取决于粘连的程度。我们报告了一例60岁女性的病例，该患者因乳腺癌化疗使用TIVAD已达12年。由于导管远端粘连，移除具有挑战性，但经过仔细解剖和牵引最终成功移除。
