When assessing upper extremity central venous thrombosis, which additional veins should be evaluated?

When assessing upper extremity central venous thrombosis, it is essential to evaluate the neck veins. The upper extremity venous system is interconnected with the neck veins, particularly through the internal and external jugular veins and the subclavian veins. Thrombosis in the upper extremities often affects or may originate from these areas, as well as presenting potential complications or concomitant issues in the neck veins.

Evaluating the neck veins can provide insight into the extent of the thrombotic event and help identify other areas of potential occlusion. Moreover, conditions like thoracic outlet syndrome or the presence of central venous catheters can lead to thrombosis in both the upper extremity and neck veins, necessitating a thorough examination.

On the other hand, abdominal, pulmonary, and femoral veins are not directly related to the assessment of upper extremity central venous thrombosis. Their evaluation would not provide the necessary information regarding the thrombosis present in the upper extremities. Understanding the connections within the venous system allows for a comprehensive assessment and reduces the risk of overlooking significant pathology.
