AbstractA totally implanted system for improved central venous access has been investigated during 44 procedures in 38 patients (37 with cancer and one with cerebral infarction). Most of them lacked peripheral venous sites, and ten per cent of the patients had a prior chronic external central venous catheter. This system is implanted using local anesthesia and consists of a port connected to a central venous catheter threaded through the subclavian vein into the superior vena cava. The system was used mainly for intermittent administration. Injections and infusions of virtually all classes of antineoplastic drugs or antibiotics (81%), blood components (26%), hyperosmolar total parenteral nutrition (47%), and intravenous solutions (53%) were administered through the system. Twenty-one patients died with the system still functioning. Ten of the systems were eventually removed, either after completion of therapy (1) or because of a complication (9). In another 13 cases the devices were working at the completion of the study. Infections accounted for nine per cent of port complications. Four systems became occluded and two of them were replaced. Overall patient acceptance was excellent. This system can be assigned to an appropriate setting that facilitates management of the cancer patient.
