A score derived from the Project of Ex-Vivo Graft Engineering via Transfection III aatabase (PREVENT III) can be used to evaluate a patient with critical limb ischemia.
Parameters:
(1) dialysis-dependent renal failure
(2) tissue loss (non-healing ulcer or gangrene)
(3) age
(4) hematocrit (as indicator of anemia)
(5) history of advanced coronary artery disease (CAD)
