Key Points

To assess the role of psoas muscle area in predicting spinal cord ischemia after endovascular aortic repair procedures.
Analyzed psoas muscle area via preoperative CTA imaging.
Compared two-dimensional and volumetric measurements of iliopsoas muscle.
Evaluated incidence of spinal cord ischemia after fenestrated and branched endovascular aortic repair.
Psoas muscle area was a significant predictor of spinal cord ischemia.
Preoperative signs of sarcopenia correlated with higher risk of ischemia.
Volumetric measurements did not improve prediction compared to two-dimensional assessments.

Implication

Evaluation of psoas muscle area predicts spinal cord ischemia after endovascular aortic repair, indicating risk factors.

Abstract

Psoas muscle area was independently associated with SCI after F/B-EVAR, indicating that patients with signs of sarcopenia on preoperative CTA may be at higher risk for SCI. Volumetric iliopsoas muscle measurements were not better predictors of SCI than two-dimensional measurements of the psoas muscle area.
