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

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.

A modified internal jugular vein access for long-term catheter placement in cancer patients.

Background: Placement, handling, and maintenance of indwelling central venous access devices may be difficult due to anatomical, clinical, or hematologic conditions in many cancer patients needing chemotherapy. An alternative approach technique is suggested joining surgical dissection to venipuncture, assisted by fluoroscopy, as a secure way to avoid complications of long-term indwelling catheters. Although ultrasound guided puncture is a safe procedure, it is not always available or familiar to most surgeons.
