Radiologic findings of normal and compromised thoracic venous catheters.
We review the radiologic findings of normal positioning, malpositioning, and complications related to the more commonly used thoracic venous catheters. These include central venous catheters, long-term central venous access catheters, and pulmonary artery catheters. The radiologist plays an important role in the early recognition of the complications of these catheters. The daily practice of chest radiology is intimately related to the evaluation of the integrity and correct placement of thoracic venous catheters. The purpose of this pictorial essay is to review radiologic findings of normal positioning, malpositioning, and complications related to the more common devices used, including central venous catheters, long-term central venous access catheters, and pulmonary artery catheters. Many of the complications described are serious and may remain unrecognized for a long time; this may cause incorrect diagnosis and delayed treatment. The radiologist plays an important role in the early recognition of these complications. Malpositioning and complications often are more easily diagnosed with contrast-enhanced studies and computed tomography.
