Escalas de riesgo preoperatorio para el tratamiento endovascular de aneurismas aórticos

Introduction: The aim of this study is to analyse the usefulness of two preoperative risk scales in the endovascular repair of abdominal aortic aneurysms in routine clinical practice.Patients and methods: A retrospective study was conducted on the morbidity and mortality at 30 days in 50 consecutive patients with an aortic aneurysm repaired by endovascular treatment. The Egorova-Giacovelli scale (EE-G) and Glasgow Aneurysm Scale (GAS) were used on all patients. A statistical analysis of the means, ROC curves, and risk was performed using the published cut-off point for both scales.Results: The mortality at 30 days was 4%, and the morbidity 12%, with both groups having a medium to high score on both scales. The analysis of the ROC curves showed good agreement, with an area under the curve (AUC) in the EE- G of 0.781 (95% CI: 0.543-1.020; P =.181) for the mortality and 0.831 (95% CI: 0.675- 0.988; P =.009) for the morbidity. The AUC in the GAS was 0.839 (95% CI: 0.684-0.993; P =.108) for mortality and 0.917 (0.835-0.999; P =.001) for the morbidity. When the cut-off points were used, the mortality increased from 2% to 20% (OR: 11) with the EE-G and from 2% to 8% (OR: 3.36) with the GAS; the morbidity increased from 6% to 60% (OR: 21) with the EE-G and from 2% to 41% (OR: 26.42) with the GAS.Conclusions: These types of scales may help to determine the patient group with a higher risk of having complications in these types of procedures.
