Percutaneous Endovascular Retrieval of an Embolized Chemotherapy Port-A-Cath Fragment from the Superior Vena Cava Utilizing a Snare System: A Case Report

Abstract

Port catheters are recommended for patients requiring long-term intravenous therapy, particularly in cancer patients who are debilitated and require administration of chemotherapy or cytotoxic drugs. Mechanical complications of port placement include port occlusion, displacement, and catheter fracture. In this case report, we present the endovascular retrieval of a fractured chemotherapy port catheter fragment from the superior vena cava using a snare device. A 60-year-old woman with metastatic breast cancer presented with infusion difficulty through her 18-monthold subclavian chemotherapy port. The surgeon noticed that the port had not been fully extracted, prompting an urgent consultation for intervention. Fluoroscopyguided retrieval of an SVC catheter fragment was achieved via femoral access using an Amplatz snare after failed EN Snare attempts. The patient was discharged postprocedure without complications. Proactive chemotherapy port surveillance enables early complication management. Catheter fractures necessitate multidisciplinary care,
where endovascular snare retrieval augmented by surgical excision demonstrates optimal safety and efficacy.
