The surgery of the long-term central venous accesses in oncology

• The practice of Central Venous Catheter placements applied to surgical oncology.
• The clinical and anatomical pitfalls hampering the surgery of implantation.
• The tactical and technical resources to get long-term indwelling from a catheter.
• The surgical oncology expertise as a specialty in conducting this process.

The implantation of Long-Term Central Venous Catheters (LTCVC) in cancer patients has been essential to conduct the oncological treatments of today. The complexity of the protocols requires accuracy on the management of such devices in order to keep them long-functioning. The article focuses on such subject from an oncological perspective, pointing out threats of the disease to the central venous system (CVS) and the ways to face them successfully. The most salient points related to surgical techniques and the insights to follow-up long-term inserted catheters are discussed. An anatomical classification is suggested to help understand occurrence of malpositions and to north the necessary maneuvers of repositioning. Such matters are based on 3000 LTCVC-placements performed by the author at the Brazilian National Cancer Institute (INCA) between 1999 and 2011. As nearly 30% of the patients presented some sort of anatomical disorder at the moment of the surgery, it was judged worthy to address such experience to those young surgical oncologists willing to tackle LTCVCs in Cancer Units.
