RESUMEN
OBJECTIVE: Acute limb ischemia is a common clinical manifestation of embolism or thrombosis, which can lead to amputation. Increasing evidence suggests that various biomarkers can predict amputation at the time of admission. Identifying an easily obtainable and inexpensive indicator has always been a major objective. The aim of this study was to determine the predictive value of the admission monocyte count to the HDL-C ratio for a lower extremity amputation in patients undergoing embolectomy for acute limb ischemia. PATIENTS AND METHODS: This retrospective, single-center study included 269 patients who underwent an emergent embolectomy. The study population was divided into two groups according to early amputation: the non-amputation group (n = 220) and the amputation group (n = 49). Two groups were compared based on various data. RESULTS: According to the multivariate regression analysis, patients with a higher CRP and MHR have a significantly higher amputation rate (HR: 1.148; CI: 1.075-1.225; p < 0.001 and HR: 1.547; CI: 1.003-2.387; p = 0.04, respectively). Patients with arterial back bleeding have a significantly lower amputation rate (HR: 0.106; CI: 0.02-0.558; p = 0.008). CONCLUSIONS: Our study demonstrated that preoperative CRP, MHR, and no arterial back bleeding after surgery were found to be independent predictors of amputation as a poor prognostic factor within 30 days after an embolectomy.
