In this review We investigated whether the total psoas area (TPA) measured at the L3-L4 vertebral levels can be used to predict postoperative outcomes in patients undergoing open revascularization procedures for chronic limb-threatening ischemia (CLTI).
In this retrospective cohort study, patient biomarkers were measured from preoperative computed tomography images (<6 months before procedure) and correlated with patient outcomes, including major limb amputation, mortality, and changes in ambulation, assessed perioperatively and at 6, 12, and 60 months postoperatively. The presence of significant differences in the TPA between patients who had died and those who survived suggests that novel, noninvasive biomarkers, such as TPA, might be clinically useful in predicting the risk of such complications after revascularization. Further analysis is necessary to determine the precise TPA thresholds to more effectively predict the risk of postoperative complications in patients with CLTI before open revascularization procedures. These differences were independent of sex and procedure. Patients who had undergone major limb amputation did not have significant differences in the TPA. Finally, patients who had experienced losses in baseline amputation after 12 and 60 months postoperatively had had a significantly lower TPA measured at the superior border of L4.
