Anatomical basis of central venous catheter fracture.
ABSTRACT Central venous catheter fracture is a rare complication of long-term indwelling subclavian venous access. Subclavian vein access has been the recommended approach for placing central venous catheters. The anatomical landmark method for subclavian access remains a highly successful and nonequipment-dependent method for rapid central access. More recently, the internal jugular vein approach has emerged as the preferred route for long-term central venous access. However, variations in internal jugular vein anatomy make the landmark method less reliable. Use of two-dimensional real-time ultrasound during internal jugular vein access is associated with better success, a lower complication rate, and faster access. A case of central venous catheter fracture initiated an internal review of long-term central venous access procedures. We have converted to a predominantly internal jugular vein approach. This case report and literature review may assist other physicians and institutions in re-evaluating long-term central venous access protocols.

ABSTRACT: Adequate vascular access is of paramount importance in oncology patients. It is important in the initial phase of surgical treatment or chemotherapy, as well as in the chronic management of advanced cancer and in the palliative care setting. We present an overview of the available vascular access devices and of the most relevant issues regarding insertion and management of vascular access. Particular emphasis is given to the use of ultrasound guidance as the preferred technique of insertion, which has dramatically decreased insertion-related complications. Vascular access management has considerably improved after the publication of effective guidelines for the appropriate nursing of the vascular device, which has reduced the risk of late complications, such as catheter-related bloodstream infection. However, many areas of clinical practice are still lacking an evidence-based background, such as the choice of the most appropriate vascular access device in each clinical situation, as well as prevention and treatment of thrombosis. We suggest an approach to the choice of the most appropriate vascular access device for the oncology patient, based on the literature available to date.CA A Cancer Journal for Clinicians 58(6):323-46. · 101.78 Impact Factor
