Ito et al reported the Sarcopenia Aneurysm Score which predicts survival after endovascular repair of an abdominal aortic aneurysm (EVAR). The authors are from Jikei University in Kashiwa, Japan.
Patient selection: status post endovascular repair of an abdominal aortic aneurysm
Parameters:
(1) sex
(2) psoas muscle index (PMI) in square cm per square meter of body height
(3) age of the patient in years
(4) aneurysm diameter in mm
(5) eGFR in mL per min per 1.73 square meters
