[Totally implantable systems in oncology: the cephalic vein as an elective access port]

The use of totally implantable systems (TIS) has noticeably reduced risks and enhanced quality of life for cancer patients undergoing long-term chemotherapy. One aspect remains open to discussion: site of venous access and placement procedure. Opinions are divided between two techniques: percutaneous access by direct puncture of the subclavian vein or surgical access through the veins afferent to the subclavian: the cephalic, the jugular, or other minor veins. We report our experience with 63 patients undergoing surgical placement of TIS through the cephalic vein. The operatory procedure is divided into four phases: 1) Preparation of vein and cannulation; 2) X-ray control; 3) creation of subcutaneous sheath; 4) reconstruction. None of the 63 patients developed immediate complications. 46 patients are currently using TIS for a period ranging from 17 to 1862 days. 16 patients died during the time their TIS was in place. In only one patient was the TIS removed after treatment was completed. From our results it is clear that the surgical access through the cephalic vein is the most reliable method of TIS placement, with fewer risks concerning immediate and post operatory complications.
