Risk Score of Egorova for Identifying a High-Risk Patient for Endovascular Repair (EVAR) of an Abdominal Aortic Aneurysm (AAA)

Description

Egorova et al developed a score for identifying a patient at high risk for an endovascular repair of an abdominal aortic aneurysm. This can help to identify a patient who may benefit from more aggressive management or who should receive alternative therapy. The authors are from Mount Sinai School of Medicine, Columbia Weill Cornell and University of Wisconsin.

Patient selection: abdominal aortic aneurysm

Outcome: 30-day mortality after endovascular aneurysm repair (EVAR)

Parameters:

(1) renal function

(2) age in years

(3) gender

(4) lower extremity ischemia

(5) liver disease

(6) congestive heart failure

(7) neurological disorder

(8) chronic pulmonary disease

(9) EVAR experience of surgeon

(10) number of EVAR procedures performed at hospital per year

Parameter	Finding	Points
renal function	failure with dialysis	7
	failure without dialysis	3
	no failure	0
age in years	< 75 years	0
	75 to 79 years	1
	80 to 84 years	2
	>= 85 years	4
gender	male	0
	female	2
lower extremity ischemia	no	0
	yes	5
liver disease	no	0
	yes	3
congestive heart failure	no	0
	yes	3
neurological disorder	no	0
	yes	2
chronic pulmonary disease	no	0
	yes	1
EVAR experience	< 3	1
	>= 3	0
hospital EVAR	< 7 per year	1
	>= 7 per year	0

total score =

= SUM(points for all 10 parameters)

Interpretation:

• minimum score: 0

• maximum score: 29

• The higher the score the greater the 30-day mortality.

Performance:

• The area under the ROC curve was 0.70 to 0.73.
