Description

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).
