ABSTRACT

Abdominal aortic aneurysm is defined as a dilatation of the abdominal aorta greater than 3cm. Its prevalence is between 1 and 1.5 cases per 100 people, constituting an important cause of morbidity and mortality. Rare in women, its frequency increases with age and its most frequent location is between the renal arteries and the aorto-iliac bifurcation. Approximately 5% of cases will involve the visceral branches. It is a silent pathological process whose natural evolution is rupture, which often has a fatal outcome and whose diagnosis is part of the pathology that we will find in emergency radiology. The involvement of the radiologist and the preparation of an accurate diagnostic report, as soon as possible, is essential for decision-making by the team in charge of the patient's surgery.

ABSTRACT

OBJETIVO: Comparar los costes de la terapia endovascular (EVAR) con relación a la cirugía abierta (CA) del aneurisma de aorta abdominal (AAA). Conocer la morbimortalidad y tasa de reintervención. MATERIAL Y MÉTODOS: Realizamos un estudio de cohorte retrospectivo recogiendo los pacientes con AAA tratados entre 2008 y 2009 mediante EVAR y CA. Se halla el coste total de cada tratamiento mediante datos extraídos de la gestión analítica de nuestro centro, a partir del coste de la prótesis, tiempo de quirófano y anestesia, uso de hemoderivados, estancia en Unidad de Reanimación y estancia media. Se incluyen también costes durante el seguimiento por reintervención y pruebas de imagen. Recogimos complicaciones, mortalidad (perioperatoria y durante el seguimiento) y tasa de reintervención. El análisis estadístico se realizó mediante tablas de contingencia según modelo de Cox y prueba t de Student. RESULTADOS: Recogimos 74 casos en 2 años, 40 tratados mediante CA y 34 mediante EVAR con un seguimiento medio de 46,84 meses. La media del coste total fue 12.089,70 € para la CA y 19.682,30 € para EVAR (p < 0,0001; IC 95%: 10.952,36-13.488,11), diferencias debidas al coste de la endoprótesis que supuso el 65,7% del total. La mortalidad durante el seguimiento fue del 20% en CA (8 casos) y 31,3% (10) en EVAR (p = 0,273). La tasa de reintervención fue del 20% (8) en CA frente al 20,6% (7) en EVAR (p = 0,950). CONCLUSIONES: El tratamiento endovascular de los AAA en nuestro centro hospitalario es más caro en comparación concon la CA. La competitividad de mercado entre los diferentes dispositivos comerciales podría equiparar en un futuro ambos tratamientos


OBJECTIVE: To compare costs of endovascular repair (EVAR) with open repair (OR) in abdominal aortic aneurysms. To determine the morbidity, mortality, and reintervention rates. MATERIAL AND METHODS: A retrospective cohort study was conducted on patients with AAA that were treated during 2008-2009 with EVAR and OR, in order to obtain the total cost of each treatment. The study variables were extracted from the analytical accounting unit of our hospital. Such data consist of the cost of prosthesis, OR time, anaesthesia, blood products, intensive care unit, and length of hospital stay. Imaging tests and monitoring of patients after reintervention were also included. Complications, mortality (perioperative and follow-up) and reoperation rates, were recorded. Statistical analysis was performed using contingency tables according to a Cox model and the Student t test. RESULTS: A total of 74 cases were found in the 2 year period of the study, of whom 40 patients were treated with OR, and 34 with EVAR. The mean cost was €12,089.70 in OR and €19,682.30 for EVAR (P < .0001, 95% CI; 10,952.36-13,488.11), with the differences due to the cost of the endoprosthesis accounting for 65.7% of the total. Mortality during follow-up was 20% in OR (8 cases), and 31.3% (10) in EVAR (p =.273). The reoperation rate was 20% (8) in OR, compared to 20.6% (7) in EVAR (p =.950). CONCLUSIONS: The endovascular treatment of AAA in our hospital is more expensive compared to OR. Although the current competitive market environment could possible put both treatments on the same level in the future

ABSTRACT

OBJETIVOS: Identificar factores predictivos de mortalidad a corto plazo (<24 meses) en pacientes con aneurisma de aorta abdominal (AAA), de alto riesgo quirúrgico, tratados mediante endoprótesis. MATERIAL Y MÉTODOS: Estudio retrospectivo mediante revisión de historias clínicas entre enero de 2006 y junio de 2010. El seguimiento medio de los pacientes fue de 23,7 meses (DE = 16,3; rango: 0-62). Se compara el grupo de mortalidad a corto plazo (<24 meses) con el resto, mediante regresión logística multivariante. RESULTADOS: El 3,5% (2 casos) falleció durante el ingreso y el 30,9% (17 casos) durante el periodo de seguimiento. La media de supervivencia fue 41,1 meses (34-48,2; mediana = 40 meses). La mortalidad antes de 24 meses fue el 21% (12 pacientes). En el análisis multivariante se encontró que el único factor predictivo de mortalidad a corto plazo fue la presencia de enfermedad pulmonar obstructiva crónica (EPOC) (p = 0,014; OR 13,7; IC = 1,7-109). CONCLUSIONES: La EPOC en pacientes de alto riesgo quirúrgico parece ser indicativa de mortalidad a corto plazo


OBJECTIVES: To detect any risk factor of short-term mortality in high risk patients undergoing endovascular abdominal aortic aneurism (EVAR) repair. MATERIAL AND METHODS: A retrospective study was conducted from January 2006 to June 2010, with a mean follow-up of 23.7 months. A multiple logistic regression model was used to evaluate variables of mortality after EVAR in early mortality patients. RESULTS: Two (3.5%) cases died during hospital admission, and 30.9% during the follow-up period. Short-term mortality rate (before 24 months) was 21% (12 patients). chronic obstructive pulmonary disease (COPD) was the only significant predictor of short-term mortality (P=.014; OR 13.7; 95% CI = 1.7-109). CONCLUSIONS: COPD in high risk patients could predict short-term mortality after EVAR

ABSTRACT

INTRODUCCIÓN: La rotura del aneurisma de aorta abdominal (AAAr) continúa siendo un importante desafío para el cirujano vascular. El objetivo de nuestro estudio es analizar los resultados en el manejo de los pacientes con AAAr, comparando cirugía abierta (CA) y endovascular (EVAR) así como, identificar factores pronóstico. MATERIAL Y MÉTODOS: Estudio de 2 cohortes con AAAr, una de ellas operada mediante CA y otra tratada mediante EVAR en nuestro centro. Se incluyó, de forma consecutiva, a pacientes ingresados de forma urgente por AAAr. Se analizaron variables basales, clínicas, factores de riesgo, tiempo quirúrgico y morbimortalidad. La intervención quirúrgica (IQ) realizada dependió de la preferencia del cirujano y de las características anatómicas y clínicas de los pacientes. RESULTADOS: Desde enero de 2003 hasta diciembre de 2013 se realizaron 45 IQ, 25 (56%) mediante CA y 20 (44%) mediante EVAR. La mortalidad perioperatoria global (<30 días) fue del 64% en CA y del 50% en EVAR, sin diferencias en la supervivencia entre ambos grupos (p = 0,141). La inestabilidad hemodinámica es la única variable con repercusión en la supervivencia, hazard ratio 6,145 (IC 95%; 2,034-18,559; p = 0,001). Entre los pacientes hemodinámicamente estables la mortalidad para CA fue del 50% y del 15,4% para EVAR, sin diferencias entre ambos (p = 0,1). CONCLUSIONES: Aunque no se han encontrado diferencias estadísticamente significativas entre ambos grupos, se observan mejores resultados y con importante significación clínica en el grupo EVAR. El único factor pronóstico encontrado fue la inestabilidad hemodinámica, multiplicando por 6 veces la mortalidad


INTRODUCTION: Rupture of abdominal aortic aneurysm (rAAA) remains a major challenge for the vascular surgeon. The aim of this study is to analyze the results in the management of patients with rAAA, comparing open surgery (OS) and endovascular surgery (EVAR), as well as identifying prognostic factors. MATERIAL AND METHODS: A study was conducted on two cohorts with rAAA, one treated with open surgery and another treated with EVAR. Patients admitted for rAAA were included consecutively. Baseline and clinical variables, risk factors, surgical time, morbidity and mortality were analyzed. Surgical intervention (SI) performed depended on surgeon preference and anatomical and clinical characteristics of the patients. RESULTS: A total of 45 surgical procedures were performed between January 2003 and December 2013, 25 (56%) using OS and 20 (44%) using EVAR. The overall peri-operative mortality (<30 days) was 64% in OS and 50% in EVAR, with no significant differences in survival between the two groups (P=.141). Hemodynamic instability is the only variable with an impact on survival, hazard ratio 6.145 (IC 95%, 2.034-18.559; P=.001). In hemodynamically stable patients, mortality was 50% for OS and 15.4% for EVAR; no differences were observed between the groups (P=.1). CONCLUSIONS: Although there were no statistically significant differences between the 2 groups, better results with an important clinical relevance were observed in the EVAR group. Hemodynamic instability was the only prognostic factor found, multiplying mortality by 6

ABSTRACT

Introducción: El seguimiento de los pacientes asintomáticos con estenosis carotídea (EC) es una práctica clínica habitual pero continúa siendo controvertido dado el bajo riesgo de ictus anual. Objetivos: Conocer los niveles de progresión de la EC en pacientes asintomáticos en nuestra población y qué factores de riesgo pueden estar relacionados con la progresión de la enfermedad. Material y métodos: De forma retrospectiva, recogimos 177 estenosis carotídeas asintomáticas en 123 pacientes con una media de seguimiento de 44,65 meses realizado entre los años 2004 y 2010. Se analizaron los diferentes factores de riesgo vascular clásicos, así como la toma de tratamiento médico adecuado. El criterio de progresión se estableció en función de las velocidades pico sistólicas (VPS) iniciales y finales medidas por eco-Doppler. Finalmente, se realizó una comparación de frecuencias observadas entre los pacientes con estabilización y aquellos con progresión de la enfermedad utilizando el test de ji al cuadrado y se calcularon los riesgos relativos utilizando un modelo de Cox. Resultados: Se encontró una progresión en 42 casos (23,7%). De 56 carótidas con un grado de estenosis inicial 30-50%, 15 (26,8%) evolucionaron a 50-70% y 5 (8,9%) a >70%. De 84 que partían de 50-70%, evolucionaron a >70% 22 casos (26,2%). Del conjunto, fueron subsidiarias de cirugía 13 casos (7,3%), siendo sintomáticas 2 (1,1%). Ninguno de los factores de riesgo, incluida la toma de estatinas, demostró diferencias entre los grupos estudiados. Conclusiones: Dada la tasa de progresión media de un 23,7%, se recomienda el seguimiento con eco-Doppler en aquellos pacientes con estenosis carotídea asintomática >30%. En este estudio, ningún factor clínico o demográfico fue predictivo de progresión(AU)


Introduction: Monitoring asymptomatic patients with Carotid Stenosis (CS) is a standard dynamical practice but it still has controversy due to the low annual risk of strokes. Objectives: To know the levels of progression of CS in asymptomatic patients in our population and which factors of risk can be related with the progression of the disease. Material and methods: In a retrospective way, we collected 177 asymptomatic CS in 123 patients with a following average time of 44,65 months between the years 2004 and 2010. Different factors of classical vascular risks were analyzed and also the appropriate medical treatment was applied. The criterion of the progression was established based on the peak systolic velocities (PSV) at the beginning and at the end measured by Doppler ultrasonography. Finally, a comparison of the observed frequencies between patients with stabilization and patients with disease progression was realised using the Chi-squared test and the relative risks were calculated using a Cox model. Results: We found a progression in 42 cases (23,7%). Of 56 cases with an initial degree of 30-50%, 15 (26,8%) evolved to 50-70%, and 5 (8,9%) to more than 70%. Of 84 cases with an initial degree of 50-70%, 22 (26,2%) evolved to more than 70%. Of the group, 13 cases (7,3%) were candidates of surgery, being 2 (1,1%) symptomatic. None of the factors of risks, including taking statins, showed any difference between the groups. Conclusions: Given that the average of progression is 23,7%, it is recommended to follow it up with Doppler ultrasonography in those patients with more than 30% asymptomatic CS. In this study, no clinic or demographic factors were predictive of progression(AU)
