ABSTRACT
OBJECTIVE: Demonstrate that simplified ERICVA (Valladolid Critical Limb Ischaemia Risk Scale) is useful in predicting amputation in chronic limb-threatening ischemia (CLI) after one year of revascularization. METHODS: A retrospective cohort study was performed. We analyzed the medical records of 93 patients over the age of 35 with the diagnosis of CLI who were treated in the Department of Internal Medicine, Orthopedics or in the Cardiovascular Surgery Unit of the Víctor Lazarte Echegaray Hospital and the High Complexity Virgen de La Puerta Hospital during the period 2015-2018. The simplified ERICVA score was determined in patients before surgical and endovascular revascularization. We included 31 patients who scored 2 or more points in the exposed group and 62 patients who scored less than 2 points in the group not exposed to amputation risk. The collected data was analyzed with the statistical program SPSS where the Relative Risk and significance was obtained with Pearson's Chi-square. The multivariate analysis was also carried out in order to obtain the adjusted relative risk. RESULTS: It was identified that the simplified ERICVA score greater than or equal to 2 points was more frequent in those who underwent amputation (90.3%) compared to patients who did not undergo amputation (4.8%), increasing the risk of amputation in those patients with CLI who underwent revascularization (RR: 18.67, P<0.001). It was also possible to identify that within the group of patients that showed a high risk of amputation according to the ERICVA scale, they had a higher risk of major amputation (RR: 9.32, P<0.001) as opposed to the risk of minor amputation (RR: 1, 89, P=0.193). Among the items of the simplified ERICVA scale, the preoperative neutrophil-lymphocyte ratio and hematocrit were significantly higher in the group of amputated patients (P<0.001). In addition, it was possible to identify that the score greater than or equal to 2 was independently associated with the risk of amputation in patients revascularized with CLI (RR: 13.5, P<0.001). CONCLUSION: In our patient population, the simplified ERICVA scale is useful in predicting major and minor amputation in critical limb ischemia after revascularization. The present data showed that the patients who had a simplified ERICVA score greater than or equal to 2 had a higher risk of major amputation compared to the risk of minor amputation. However, it is important to highlight that the impact on the prediction of minor amputation is greater because in some circumstances major amputation can appear as a complication of CLI.

Objetivo: Evaluar factores asociados a la efectividad de la safenectomía parcial (SP) y total (ST) en pacientes intervenidos en el Hospital Militar Central (HMC) "Luis Arias Schreiber" durante el año 2017. Materiales y métodos: Estudio transversal. Se evaluaron historias clínicas de pacientes operados por insuficiencia venosa periférica en el HMC durante el periodo de enero - diciembre del año 2017. Se evaluaron variables como edad, género, comorbilidades (diabetes tipo 2, hipertensión arterial y obesidad), tiempo de enfermedad (en años), ubicación quirúrgica, tiempo operatorio, presencia de complicaciones (hematoma, infección de sitio operatorio y lesión del nervio safeno), días de hospitalización y mejoría clínica referida. Se buscó asociación entre estas variables y el tipo de safenectomía realizada (SP o ST) mediante la prueba de Chi cuadrado, prueba exacta de Fisher, razones de prevalencias (RP) y U de Mann- Whitney. Adicionalmente se evaluaron factores asociados a la lesión del nervio safeno en el grupo de ST, mediante regresión logística. Resultados: Se evaluaron 107 historias clínicas, 43 personas se sometieron a SP (40,2%) y 64 a ST (59.8%), con una mediana de edad de 58 años, en su mayor parte varones (64,5%). No hubo diferencias significativas entre las características clínico-epidemiológicas prequirúrgicas y el tipo de cirugía a la que se sometieron. Se encontró una menor proporción de complicaciones posoperatorias (RP (IC95%): 0,06 (0,01- 0,22)), lesión del nervio safeno (RP (IC95%): 0,02 (0,00-0,19)) y días de hospitalización (p<0,05) en los pacientes con SP. Conclusión: pacientes con SP presentaron mejores desenlaces posoperatorios (frecuencia de complicaciones posoperatorias, lesión del nervio safeno y días de hospitalización) en comparación con los que recibieron ST. Futuros estudios deberían estudiar las posibles variables intervinientes en estos desenlaces.
Objective: To assess associated factors for the effectiveness of partial (PS) and total (TS) saphenectomy performed in patients from the Luis Arias-Schereiber Central Military Hospital (CMH) during 2017. Materials and methods: This is a cross-sectional study. Clinical records from CMH patients who underwent surgery because of peripheral venous insufficiency from January to December 2017 were reviewed. The following variables were assessed: age, gender, comorbidities (type 2 diabetes, high blood pressure, and obesity), time with the disease (in years), surgical location, operative time, occurrence of complications (hematoma, operative site infection, and saphenous nerve lesion), days of hospital stay, and declared clinical improvement. Associations amongst these variables and the type of performed saphenectomy (PS or TS) were sought for by using the Chi-square test, Fisher's exact test, prevalence rates (PR), and the Mann-Whitney U test. Also, factor associated to a lesion in the saphenous nerve were assessed in the TS group using logistic regression. Results: One-hundred and seven clinical records were reviewed, 43 persons underwent PS (40.2%) and 64 underwent TS (59.8%), their mean age was 58 years, and nearly two-thirds of all patients were male (64.5%). There were no significant differences with respect to presurgical clinical and epidemiological characteristics and the type of surgical procedure performed. There were low rates of postoperative complications (PR (95% CI): 0.06 (0.01- 0.22)), saphenous nerve lesions (PR (95% CI): 0.02 (0.00-0.19)), and days hospitalized (p<0.05) in patients who underwent PS. Conclusion: Patients who underwent PS had better postoperative outcomes (frequency of postoperative complications, saphenous nerve lesions and hospitalization days) compared to those who had undergone TS. Future studies should assess the variables that might lead to these outcomes.
