Abstract

Embolization of port-a-cath fragments, while uncommon, can lead to serious complications that demand prompt intervention. We report our single-center experience with percutaneous retrieval of embolized port-a-cath fragments, evaluating the feasibility and safety of endovascular techniques. This retrospective study included 10 patients (6 men, 4 women; aged 62–78 years) who underwent port-a-cath implantation at our institution between January 2017 and December 2021. All patients were asymptomatic, and embolized catheter fragments were incidentally identified on routine chest radiographs. Percutaneous retrieval was performed in all cases using the gooseneck loop snare. Demographic data, procedural details, and complications were recorded. Among 1,615 implanted catheters, 10 cases (0.6%) of embolization were identified, occurring either early (30 days; 7 cases). The retrieval procedure was performed within 24 hours of diagnosis in all patients. The gooseneck loop snare technique was successfully employed in each case, achieving a 100% technical success rate. No procedure-related complications, including arrhythmias or vascular injury, were observed. Percutaneous endovascular retrieval of embolized port-a-cath fragments is a safe and highly effective technique. The gooseneck loop snare technique is the preferred method due to its high success rate and minimal risk. Prompt intervention is recommended regardless of the duration since embolization to prevent potential life-threatening complications.
