Constans et al developed a clinical prediction score to help in the diagnosis of upper extremity deep vein thrombosis (UEDVT). The authors are from CHU de Bordeaux, Bordeaux II University and CHU Grenoble.
Patient selection: suspicion of upper extremity deep vein thrombosis (UEDVT)
Parameters:
(1) venous material (venous catheter or access device in subclavian or jugular vein, or pacemaker)
(2) localized pain
(3) unilateral pitting edema
(4) alternative diagnosis at least as plausible

total score =
= SUM(points for all 4 parameters)
Interpretation:
• minimum score: -1
• maximum score: 3
• The higher the score the greater the risk of upper extremity deep vein thrombosis.
• To get a rate of 9-13% for a person at low risk indicates that the pre-test probability has to be above normal (patient selection of patient suspected of UEDVT).

Performance:
• The area under the ROC curve ranged from 0.68 to 0.76.
Purpose: To evaluate a patient suspected of having a deep vein thrombosis of the upper extremity using the clinical prediction score of Constans et al.
