RESUMO
INTRODUCTION: The cannulation of suitable peripheral veins may be a very painful experience. Implantable venous access systems have to some degree relieved this problem and help to provide an improvement in terms of quality of life. MATERIAL AND METHODS: We have evaluated 560 patients during a follow up period of two years. A low overall complication percentage of 7.32% was seen when using the venous access device. RESULTS: Complications and treatments were: pneumothorax; portal rotation or infection; catheter infection; embolism and migration; extravasation; partial or total obstruction of the device; rupture of the catheter or the membrane. CONCLUSIONS: There is no other system that allows repeated venous access on such a long term basis. Placing the devices completely under the skin allows the patient to conduct a normal life style, and its maintenance does not need any special care, with the exception of the monthly heparinised serum infusion. The preferred option is to insert the catheter through the cephalic vein in the delto pectoral groove.
