[Technique, indications, and immediate complications of percutaneously implanted catheters]

Implantation of a device for long-term venous access is a simple procedure that can often be done under local anesthesia, with potentiation if needed. The implantation technique involves puncture of a large venous trunk and creation of a subcutaneous space in which the device can be lodged. Although complications are rare, patients should receive strict surveillance both during the immediate postoperative period and throughout use of the device.
