SAN NORBERTO, Enrique M. et al. Anarcyl scale (ruptured aortic aneurysms Castilla y León) for predicting mortality in ruptured abdominal aortic aneurysms. Angiología [online]. 2020, vol.72, n.3, pp.126-134. Epub 02-Nov-2020. ISSN 1695-2987. https://dx.doi.org/10.20960/angiologia.00087.
Introduction:
the ruptured abdominal aortic aneurysm (AAAr), despite diagnostic and therapeutic advances, continues to present a high mortality. Although endovascular repair (EVAR) increases the number of patients who are offered surgical treatment, it is not without complications.
Objective:
design a preoperative risk scale for patients with AAAr treated by EVAR.
Material and methods:
prospective study of 34 patients undergoing EVAR of AAAr in Castilla y León between June 2016 and June 2019. Comorbidities, preoperative variables of hemodynamic stability, analytical at admission, as well as in-hospital morbidity and mortality were collected.
Results:
in-hospital mortality was 52.9%. The univariate predictors obtained were heart rate, hemoglobin, creatinine, sodium, GOT, LDH and ultrasensitive troponin T as prognostic factors. After completing the multivariate analysis, heart rate (p = 0.011), hemoglobin (p = 0.035) and creatinine (p = 0.019) were statistically different between the groups. The scale resulting from the following mortality formula: 0.440 + 0.560 (if hemoglobin < 7 mg/dl) + 0.169 (if heart rate < 70 beats/min) + 0.084 (if creatinine > 2.8). This model obtained an area under the curve of 0.870 (Fig. 1). A score < 0.440 is associated with a mortality of 39.1%, a score between 0.441-0.644 with 66.7% and 100% if > 0.644.
Conclusion:
the heart rate at admission and the analytical levels of hemoglobin and creatinine, are predictive factors of in-hospital mortality in patients with AAAr treated with endovascular exclusion. The application of the proposed scale allows the detection of patients who would not benefit from the endovascular surgical treatment of AAAr.
