ABSTRACT
OBJECTIVES: To analyze the outcome of vascular procedures performed in patients with COVID-19 infection during the 2020 pandemic. METHODS: This is a multicenter, prospective observational cohort study. We analyzed data from 75 patients with COVID-19 infection undergoing vascular surgery procedures in 17 hospitals across Spain and Andorra between March and May 2020. The primary end point was 30-day mortality. Clinical Trials registry number NCT04333693. RESULTS: The mean age was 70.9 (45-94) and 58 (77.0%) patients were male. Around 70.7% had postoperative complications, 36.0% of patients experienced respiratory failure, 22.7% acute renal failure, and 22.7% acute respiratory distress syndrome (ARDS). All-cause 30-days mortality rate was 37.3%. Multivariate analysis identified age >65 years (P = 0.009), American Society of Anesthesiologists (ASA) classification IV (P = 0.004), preoperative lymphocyte count <0.6 (×109/L) (P = 0.001) and lactate dehydrogenase (LDH) >500 (UI/L) (P = 0.004), need for invasive ventilation (P = 0.043), postoperative acute renal failure (P = 0.001), ARDS (P = 0.003) and major amputation (P = 0.009) as independent variables associated with mortality. Preoperative coma (P = 0.001), quick Sepsis Related Organ Failure Assessment (qSOFA) score ≥2 (P = 0.043), lymphocytes <0.6 (×109/L) (P = 0.019) leucocytes >11.5 (×109/L) (P = 0.007) and serum ferritin >1800 mg/dL (P = 0.004), bilateral lung infiltrates on thorax computed tomography (P = 0.025), and postoperative acute renal failure (P = 0.009) increased the risk of postoperative ARDS. qSOFA score ≥2 was the only risk factor associated with postoperative sepsis (P = 0.041). CONCLUSIONS: Patients with COVID-19 infection undergoing vascular surgery procedures showed poor 30-days survival. Age >65 years, preoperative lymphocytes <0.6 (x109/L) and LDH >500 (UI/L), and postoperative acute renal failure, ARDS and need for major amputation were identified as prognostic factors of 30-days mortality.

Introducción: En el tratamiento endovascular de los aneurismas de aorta abdominal, en el 20-40% de los casos el anclaje en la iliaca no es posible por afectación de la misma. Actualmente es posible el sellado de la endoprótesis en la iliaca externa preservando la permeabilidad de la arteria hipogástrica con dispositivos con ramas iliacas. Objetivo: Evaluar la eficacia y la seguridad del dispositivo IBE GORE® y sus resultados a un año para el tratamiento de los aneurismas aortoiliacos con dilatación de la arteria iliaca común. Material y métodos: Se trata de un estudio multicéntrico y retrospectivo con un seguimiento de 12 meses. Se incluyen 14 pacientes a los que se les han implantado 18 IBE GORE®. A todos se les ha practicado una TC antes de la cirugía y al menos una TC al mes y otra al año como protocolo de seguimiento. Resultados: El éxito técnico ha sido del 100%. A los 30 días, la mortalidad ha sido del 0%. Hubo una trombosis completa de un dispositivo que requirió un bypass cruzado y una oclusión de hipogástrica asintomática. Al año, el diámetro medio de la iliaca ha pasado de 37,3 a 31,4 mm (ha disminuido en el 87,5% de los casos) y no ha habido reintervenciones. La tasa global de endofugas tipo II de la serie ha sido del 21%, la permeabilidad del cuerpo del branch, del 94% (17/18), y la del componente de hipogástrica, del 89% (16/18). Conclusiones: El tratamiento de aneurismas aortoiliacos que afectan a la arteria hipogástrica con el dispositivo IBE GORE® es seguro, eficaz y permite preservar la permeabilidad de la hipogástrica (AU)
Introduction: In 20-40% of cases of endovascular aneurysm repair, the regular sealing in common iliac artery is not possible because of the severity of the disease. Nowadays, improved devices provide the possibility of a correct sealing in external iliac artery, preserving the hypogastric patency. Objective: The aim of this study is to evaluate the safety and efficacy of the IBE GORE® device and its one year results in the treatment of abdominal aorta-iliac aneurysms. Material and methods: A total of 14 patients treated with 18 IBE GORE® devices were evaluated in a multicentre and prospective study, and followed-up during a 12 month period. All of them had a CT scan prior to surgery, at one month, and at one year as required in the follow-up protocol. Results: There was 100% technical success. The 30 day follow-up mortality was 0%, with one complete occlusion of the iliac branch that needed a femoro-femoral bypass, and one asymptomatic hypogastric occlusion. The mean iliac artery diameter went from 37.3 to 31.4 mm after one year (decreased in 87.5% of patients), and no re-interventions were needed. The overall type II endoleak was 21%, the patency of the body of the branch was 94% (17/18), and the hypogastric component 89% (16/18). Conclusions: Endovascular treatment of aorto-iliac aneurysms affecting the internal iliac artery using the IBE GORE® device is safe, effective, and preserves hypogastric patency (AU)

INTRODUCCIÓN: La anemia es muy frecuente en los pacientes sometidos a cirugía vascular y puede influir en los resultados postoperatorios. OBJETIVOS: Evaluar la prevalencia de anemia en los pacientes intervenidos de cirugía arterial aortoilíaca e infrainguinal. Analizar la influencia de la anemia en la aparición de complicaciones postoperatorias. MATERIAL Y MÉTODOS: Se ha realizado un estudio retrospectivo, transversal y multicéntrico en 12 unidades de cirugía vascular. Se han registrado las cifras de hemoglobina de todos los pacientes que han sido intervenidos de forma consecutiva durante 2 meses. Además se han registrado los factores de riesgo de arteriosclerosis habituales y las complicaciones postoperatorias hasta 30 días de la cirugía. RESULTADOS: Se han registrado 530 pacientes. La tasa global de anemia ha sido del 53,8%, siendo del 50,8% en hombres y del 62,2% en mujeres. El 66,9% de los pacientes con isquemia crónica crítica tiene anemia. Los anémicos son mayores que los no anémicos y son más frecuentemente hipertensos, diabéticos, tienen más insuficiencia cardiaca y renal, y presentan unas cifras más elevadas de proteína C reactiva. Además también presentan anemia previa (hasta 3 meses) con más frecuencia, tienen una mayor estancia hospitalaria (10,4 vs. 7,0) y reciben más transfusiones. Los anémicos no presentan más complicaciones ostoperatorias pero en el análisis multivariante la enfermedad pulmonar obstructiva crónica y la anemia en los 3 meses anteriores son factores predictores de complicaciones. CONCLUSIONES: La prevalencia de anemia en los pacientes con arteriopatía periférica severa es muy elevada. Los pacientes anémicos en el preoperatorio se transfunden 3 veces más y tiene una estancia hospitalaria más larga que los no anémicos. La anemia en los 3 meses anteriores a la cirugía es un factor predictor de complicaciones postoperatorias
INTRODUCTION: Anaemia is very common in patients subjected to vascular surgery and can influence the post-operative outcome. OBJECTIVES: To evaluate the prevalence of anaemia in patients undergoing aortoiliac and infra-inguinal vascular surgery. To analyse the influence of the anaemia on the presentation of post-operative complications. MATERIAL AND METHODS: A retrospective, cross-sectional, multicentre study was conducted in 12 vascular surgery units. The haemoglobin levels were recorded on all patients that had been consecutively intervened over a period of 2 months. The usual arteriosclerosis risk factors were recorded, as well as the post-operative complications up to 30 days from the surgery. RESULTS: A total of 530 patients were included. The overall rate of anaemia was 53.8%, with 50.8% in males and 62.2% in females. More than two-thirds (66.9%) of patients with chronic critical ischaemia had anaemia. There were more anaemic patients than non-anaemic ones, and they more frequently have hypertension and diabetes. They also present with more cardiac and renal failure, and have a more elevated C-reactive protein levels. They also have previous anaemia (up to 3 months) more often, have a longer hospital stay (10.4 vs. 7.0), and receive more transfusions. They do not have more post-operative complications, but chronic obstructive pulmonary disease and anaemia in the previous 3 months are predictive factors of complications. CONCLUSIONS: Anaemia prevalence id very high in patients with severe peripheral arterial disease. Patients that are anaemic in the pre-operative period are transfused three times more and have a longer hospital stay than non-anaemic patients. Anaemia in the 3 months before the surgery is a predictive factor for post-operative complications
