Upper Extremity Deep Vein Thrombosis [UEDVT]: Risk Assessment Algorithms


Upper extremity deep vein thrombosis accounts for 4-10% of cases of deep vein thrombosis but the management of such cases can be problematic as the event is objectively confirmed in only 13–30% of symptomatic subjects. 

A clinical decision rule combined with D-dimer testing has been developed to allow the risk stratification of patients with a suspected UEDVT and in individuals with a low score, to avoid imaging.

The Constans Clinical Decision Score

The Constans Clinical Decision Score uses 4 variables to risk stratify patients with a suspected UEDVT.  The score was designed by a multivariate logistic regression analysis of
a sample of patients hospitalized for suspicion of UEDVT and then subsequently validated in subsequent studies.
