Clinical Prediction Score of Constans et al for Lower Limb Deep Vein Thrombosis in a Symptomatic Hospitalized Patient (Saint-Andre Hospital Score)

Description

Constans et al developed a score for predicting lower limb deep vein thrombosis (DVT) in a symptomatic hospitalized patient. This can help to guide subsequent testing of the patient. The authors are from Hopital Saint-Andre and Universite Victor Segalen Bordeaux II in Bordeaux, France.

Patient selection: hospitalized patient who is clinically suspected of having a DVT of a lower extremity

Parameters:

(1) current cancer

(2) paralysis or plaster (cast) = immobilization

(3) pittng edema affecting only one lower limb

(4) superficial venous dilation

(5) warmth

(6) other diagnosis that can explain findings

Parameter	Finding	Points
current cancer	no	0
	yes	1
paralysis or plaster	no	0
	yes	1
pitting edema of one lower limb	no	0
	yes	1
superficial venous dilation	no	0
	yes	1
warmth	no	0
	yes	1
other diagnosis	no	0
	yes	-1

total score =

= SUM(points for all 6 parameters)

Interpretation:

• minimum score: -1

• maximum score: 5

• The higher the score the greater the risk for a deep vein thrombosis.

Score	Risk of DVT	Percent
>= 3	high	76%
1 or 2	intermediate	33%
0	low-intermediate	11%
