The interventional radiologist's role in providing and maintaining long-term central venous access

The insertion of long-term central venous access devices by interventional radiologists has become widespread. The overall success rate in image-guided device placement approaches 99%, with less than 1% incidence of pneumothorax, arterial injury, and catheter malposition. The use of image guidance and interventional radiologic techniques allows the use of a wide range of access sites in addition to the traditional jugular and subclavian veins. The cost of device placement in the radiology suite is lower than that in the operating room, and long-term outcomes are equivalent. Working in close collaboration with venous access nurse specialists, interventional radiologists also participate in the management of device-related complications.
