Radiographic evaluation of the psoas and iliopsoas muscle as predictors for spinal cord ischemia after fenestrated and branched endovascular aortic repair

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.
