Background: Carotid endarterectomy (CEA) plays a critical role in stroke prevention, but assessing a patient’s preoperative physiological reserve remains challenging. This study aimed to evaluate the impact of sarcopenia and preoperative albumin on postoperative management outcomes and resource utilization in CEA patients with a high prevalence of metabolic comorbidities. Methods: This retrospective cohort study evaluated 67 patients who underwent elective or urgent CEA between January 2015 and June 2025. Sarcopenia was quantified using the Masseter Muscle Index (MMI) derived from routine preoperative head and neck computed tomography (CT) scans. Multivariable regression models were used to assess the relationships between the MMI, serum albumin levels, and surgical outcomes. Results: The cohort had a mean age of 66.8 years and demonstrated a significant metabolic burden, with a high prevalence of diabetes (71.6%) and an average body mass index (BMI) of 28.15 kg/m2. Despite this predominantly overweight demographic, the MMI revealed underlying frailty and showed a strong inverse relationship with hospital resource utilization. A one-unit increase in the MMI significantly reduced total hospital length of stay (LOS) by 14.40 days (p = 0.001) and ICU LOS by 6.91 days (p < 0.001). Emergency surgery was the only independent predictor of mortality (OR 16.61, p = 0.047), while neither the MMI nor albumin significantly predicted short-term adverse clinical events. Conclusions: In a patient population where a higher BMI may mask underlying frailty, opportunistic screening for sarcopenia using routine preoperative CT scans provides important prognostic value. In this cohort study, a lower MMI showed an association with prolonged hospital and ICU stays; while it did not independently predict short-term mortality, its potential utility in forecasting resource utilization warrants further investigation in larger, prospective cohorts.
