Vascular Study Group of New England (VSGNE) Predictive Model for In-Hospital Mortality Associated with Elective Abdominal Aortic Aneurysm Repair

Description

Eslami et al reported a prediction model for in-hospital mortality after an elective repair of an abdominal aortic aneurysm. This can help to identify a patient who may be at excessive risk of postoperative mortality. The authors are form the Vascular Study Group of New England (VSGNE).


Patient selection: elective abdominal aorta aneurysm repair

 

Outcome: in-hospital mortality

 

Parameters:

(1) treatment approach

(2) aneurysm size in mm

(3) age in years

(4) sex/gender

(5) myocardial disease

(6) cerebrovascular disease

(7) chronic obstructive pulmonary disease (COPD)

(8) serum creatinine in mg/dL

Interpretation:

• minimum score: 0

• maximum score: 14

• The higher the score the greater the risk of mortality.
