Percutaneous implantation of port-catheter systems for intraarterial chemotherapy of the liver

Purpose. The objective of this study was to determine the usefulness, safet y and acceptance of a new technique of percutaneous implantation of port-ca theter-systems (PIPS) for locoregional intraarterial chemotherapy of the li ver. Material and methods. In 50 patients with malignant hepatic disease, 52 per cutaneously implantable port-catheter systems were implanted for intraarter ial chemotherapy of the liver as an interventional radiological technique. A commercially available angiographic catheter was placed in the hepatic ar tery under fluoroscopic control via a transfemoral approach and connected t o a Port-A-Cath situated in the groin. This procedure was done on an outpat ient basis; no medical treatment was administered. Results. Percutaneous placement of the port-catheter system was successful in all cases,also in those with a hepatomesenteric trunk. No peri- and post -interventional complications occurred. The median patency was 312 days (13 -547 days). The catheter-related complication rate was 12%. The function co uld be restored by replacement or an interventional procedure in all but on e case (2%). Infection and leakage did not occur. The system had been withd rawn without complications in 7/52 cases for a variety of reasons (e.g, hem ihepatectomy, desire of the patient or clinician, dissection after interven tion, replacement), Conclusion. Percutaneous placement of a port-catheter system is a safe and easy alternative to the surgical placement of port systems for hepatic intr aarterial chemotherapy. Long-term complication rates are comparable. The op tion of easy withdrawal and interventional correction of dysfunction as wel l as lower costs are additional advantages.
