  "abstract": "Catheter malposition is a recognized complication of totally implantable venous access ports (TIVAPs). Removal or reimplantation may be unnecessarily invasive when the catheter remains patent, whereas untreated malposition may cause thrombosis, dysfunction, or infusion-related complications. Evidence regarding pigtail catheter repositioning remains limited. This study reviews 39 cases of TIVAP catheter malposition treated using a transfemoral pigtail catheter technique. This retrospective case series included 39 patients with imaging-confirmed TIVAP catheter malposition treated between September 2018 and October 2025. Eligible catheters were patent and functional without occlusion; patients with catheter dysfunction or those managed using other repositioning methods were excluded. Under fluoroscopic guidance, a 5-F pigtail catheter was introduced through the femoral vein to redirect the catheter tip into the intended central venous position. The right internal jugular vein was the most common malposition site (25/39, 64.1%). Initial technical success was achieved in all patients, with a mean procedure duration of 13.64±5.02 minutes. No immediate procedure-related complications were documented. Recurrent malposition occurred in 2 patients during a mean follow-up of 3.9±3.7 months (range, 2-14 months). Fluoroscopy-guided transfemoral pigtail catheter repositioning is technically feasible for selected patients with a functioning, non-occluded malpositioned TIVAP and may avoid immediate catheter replacement or surgical revision.",
