exit site

Tunneled central venous catheters (CVCs) represent a specialized type of long-term vascular access device designed for patients requiring extended intravenous therapy. Unlike standard central lines, tunneled CVCs feature a subcutaneous tract between the venous entry site and the exit point on the skin, providing enhanced infection protection and improved stability. The image illustrates the anatomical positioning of a tunneled CVC, showing its path from the external exit site through a subcutaneous tunnel, into the right subclavian vein, and ultimately terminating in the superior vena cava near the right atrium.

Explore the intricacies of a non-tunneled Central Venous Access Device (CVAD) with this detailed medical illustration. This image provides a clear view of the device’s components and placement, serving as an essential resource for medical students and professionals learning about vascular access techniques. Understand the anatomy, procedure, and clinical applications of this critical medical tool through this comprehensive guide.
