Radiological placement of peripheral central venous access ports at the forearm. Technical results and long term outcome in 391 patients]

Purpose: To retrospectively analyze the technical result and long term outcome of central venous arm ports placed by radiologists. Materials and Method: Over a 5-year period, 399 arm ports were implanted by radiologists in 391 patients. The system consists of a low profile titanium chamber and a silicone catheter. Ports were placed at the forearm after puncture of a vein proximally to the elbow under fluoroscopic guidance. In a retrospective analysis the technical results and the long term outcome were evaluated. Complications were documented according to the standards of the society of interventional radiology. Results: In 391 patients a total of 98633 catheter days were documented (1 - 1325 days, mean 252 days). Primary technical success was 99.25% (396/399) with a 100% secondary technical success rate. No severe procedural complications, e.g. pneumothorax or severe hemorrhage, were found. A total of 45 complications occurred (11.28%, 0.45/1000 catheter days), including 8 portal pocket infections (27 - 205 days, mean 115 days). Fifteen ports were explanted because of complications. The complication rate corresponds to the data from subclavian ports and is less than the complication rates published in large surgical trials. Conclusion: Implantation of central-venous arm ports by radiologists is safe and minimally invasive. No severe immediate procedural complications occur due to the peripheral implantation site. Long term complication rates are comparable to other studies of radiological or surgical port implantation at different sites.
