Abstract: OBJECTIVE: To explore the clinical efficacy and safety of percutaneous transvenous retrieval of intravascular fractured catheter and to evaluate the possible reasons and final results in cancer patients. METHODS: A dataset of 19 patients was used. Percutaneous transvenous retrieval of intravascular fractured catheter was performed in each patients. Clinical data was retrospectively analyzed with respect to the efficacy, safety and outcome, and chest radiography was performed to verify that no catheter fragments were left. RESULTS: Two cases had peripherally inserted central catheter and 17 had subcutaneous implanted port catheter. The catheter fragments were located in the brachiocephalic vein-superior vena cava (n = 1), superior vena cava (n = 1), superior and inferior vena cava (n = 1), superior vena cava-right atrium (n = 2), brachiocephalic vein-superior vena cava-right atrium (n = 1), superior vena cava-right atrium-right ventricle (n = 6), brachiocephalic vein-superior vena cava-right atrium and right ventricle (n = 1) and pulmonary artery (n = 6), respectively. All of these catheter fragments were retrieved successfully. No complications such as bleeding and thrombosis were found. CONCLUSION: Percutaneous transvenous retrieval is a safe, minimally invasive and relatively simple procedure for the patients with fractured catheter and should be recommended as the first choice.
