A secure and easily feasible vascular access is crucial for oncology patients because of the therapeutic need. Although intravenous port has been utilized for 3 decades, catheter-related complication still remain and had to deal with. According to investigators clinical experience, investigators summarized a standard algorithm as a recommendation for intravenous sport implantation. The complication before and after standard algorithm was 20 % and 3.5 %, respectively. However, catheter related infection and malfunction still could not be avoided. If patient was identified with these 2 complications, re-intervention is needed and cancer-related therapy has to be postpone. Investigators deconstructed the port that removed from patients and identified there were structural weakness, old blood clot and fibrin deposits. Investigators consider the problem may be exist in maintenance. After thoroughly examination the maintenance protocol, investigators identified the problem and try to remodel the maintenance protocol. The Goal of this study was to testify the clinical value of standard maintenance protocol.
