Implantable catheter system for long-term intravenous chemotherapy

Fifty-three implantable catheter systems (Port-A-Cath) were placed subcutaneously in 48 patients with malignant tumours. This device consists of a stainless steel chamber covered by a silicone membrane connected to a silicone catheter placed in a central vein. All systems were used for administration of chemotherapy. The mean function time was 187 days (range 0-867). Complications necessitating reoperation occurred in six patients. In three cases, the catheter occluded from thromboses. In two patients, wound dehiscence occurred, and in one a wound infection developed. In one case, the catheter was disconnected from the port. Four patients who had had the port removed later received new ports. One patient had the second port removed and was given a third catheter system. It is concluded that subcutaneously implantable injection ports constitute a safe and convenient access for long-term intravenous chemotherapy. The complication rate is low, and it should be possible to avoid most recorded complications in the future.
