title: Validation of the Finnvasc score in infrainguinal percutaneous transluminal angioplasty for critical lower limb ischemia.
abstract: The aim of the present study was to validate the Finnvasc score for prediction of immediate outcome after infrainguinal percutaneous transluminal angioplasty (PTA) for critical lower limb ischemia (CLI). Our registry included prospective data on 512 patients who underwent isolated infrainguinal PTA revascularization procedures for CLI. The Finnvasc score herein evaluated was calculated by assigning one point each to diabetes, coronary artery disease, foot gangrene, and urgent operation. Early mortality and major limb amputation rates after PTA revascularization were 2.5% and 12.3%, respectively. Seventy-two patients (14.1%) died and/or had lower limb amputation. Diabetes (p = 0.001), foot gangrene (p = 0.047), urgent operation (p < 0.0001), and preoperative renal failure (p = 0.001) were independent predictors of postoperative mortality and/or major limb amputation. Finnvasc score was predictive of major lower limb amputation (p = 0.003), mortality (p < 0.0001), and mortality and/or major amputation (p < 0.0001) after PTA. Mortality, major lower limb amputation, and combined end point rates in patients with a Finnvasc score of 3-4 were 12.8%, 25.6%, and 35.9%, respectively. The Finnvasc score is a simple risk scoring method which can be useful to estimate the risk of immediate postprocedural mortality and/or major lower limb amputation also in patients undergoing infrainguinal PTA for CLI.
