Sonographic evaluation of upper extremity deep venous thrombosis.
OBJECTIVE
The purpose of this presentation is to review the techniques of performing an upper extremity Doppler examination, in addition to illustrating the sonographic appearances of acute and chronic upper extremity deep venous thrombosis (UEDVT).


METHODS
The risk factors and complications of UEDVT are discussed, and the anatomy of the upper extremity deep venous system as well as examination techniques are described. Cases of acute and chronic deep venous thrombosis were also chosen to illustrate the spectrum of sonographic appearances.


RESULTS
Color Doppler sonography is accurate in the diagnosis of UEDVT. However, in cases of equivocal Doppler findings, or when the sonographic findings are normal but clinical suspicion for central venous thrombosis is high, magnetic resonance or contrast venography is necessary for further evaluation.


CONCLUSIONS
Color Doppler sonography is a rapid and noninvasive technique in the evaluation of venous disease in the upper extremity and is the modality of choice in screening for UEDVT.
