RESUMO

BACKGROUND: Osteochondroma is the most common non-malignant tumour of bone, accounting for approximately one third of benign lesions in the skeleton. They often develop around the knee in the distal femur and in the proximal tibia and fibula. They present as a painless slow growing mass during adolescence and have been reported to cause damage to adjacent structures such as blood vessels; arterial damage is more common than venous injury and is usually a result of compression, stretching, and rubbing of the arterial wall. Such lesions include stenosis, thrombosis, and pseudoaneurysm formation possibly causing lower limb claudication or acute limb ischemia. METHODS: An 18 year old male patient with a 4 week history of pain, hematoma, and oedema of the left calf without previous trauma is reported. A computed tomography scan (CT) revealed a large popliteal artery pseudoaneurysm and its close relationship to a protrusion of the proximal tibia. RESULTS: The popliteal artery was repaired by an external saphenous patch and the exostosis was removed. The patient had palpable popliteal and distal pulses after surgery and during the first year follow-up. CONCLUSIONS: Tibial osteochondroma should be considered in the differential diagnosis in young patients, among the potential causes of pseudoaneurysm of the femoral or popliteal artery. Surgical repair should be performed to restore normal blood flow with resection of the exostosis to prevent recurrence.

RESUMO

OBJETIVO: Valorar la mortalidad y complicaciones postoperatorias durante el primer mes de los aneurismas de aorta abdominal rotos (AAAr), en función de la técnica quirúrgica empleada, reparación endovascular de aneurisma (EVAR). Analizar los factores pronósticos que influyen en la mortalidad. MATERIAL Y MÉTODOS: Estudio de cohortes históricas de los pacientes con AAAr infrarrenales y yuxtarrenales sometidos a tratamiento quirúrgico (EVAR o cirugía abierta) en nuestro centro. Los criterios de elección para EVAR son anatomía favorable y estabilidad hemodinámica. Las variables recogidas fueron características demográficas, factores de riesgo cardiovascular y patología asociada, técnica quirúrgica, lugar de procedencia, demora en la intervención, situación preoperatoria, complicaciones médico-quirúrgicas postoperatorias, estancia en unidad de reanimación posquirúrgica (URP) y en planta de hospitalización y mortalidad. RESULTADOS: Entre enero de 2011 y agosto del 2013 se intervinieron 31 varones con edad media de 71 años. La mortalidad global fue del 45% (mortalidad del 61% en cirugía abierta frente al 23% con EVAR, p 0,06). Hipotensión preoperatoria < 80 mmHg (p < 0,004), creatinina > 2,1 mg/dl (p 0,018) e inestabilidad hemodinámica en quirófano (p < 0,05) se asocian con la mortalidad de forma significativa, independientemente de la técnica quirúrgica empleada. La estancia media en URP fue de 10 días en cirugía abierta frente a 2 días en EVAR (p 0,04). La estancia media hospitalaria fue de 19 días en cirugía abierta frente a 6,5 días en EVAR. CONCLUSIONES: La introducción del EVAR para el tratamiento de los AAAr en nuestro centro ha disminuido la morbimortalidad, la estancia media en URP y en planta de hospitalización


OBJECTIVE: A study was conducted on the 30-day mortality and postoperative complications after endovascular repair (EVAR) and open surgery in patients with ruptured abdominal aortic aneurysms (rAAA). An analysis was made of the prognostic factors influencing the mortality. MATERIAL AND METHODS: A review was conducted on a cohort of patients with infrarenal and juxtarenal rAAA undergoing surgical treatment (EVAR and open surgery). The selection criteria used for EVAR were favourable anatomy and hemodynamic stability. The variables collected were demographic characteristics, cardiovascular risk factors and associated diseases, surgical technique, place of origin, delayed intervention, preoperative status, postoperative medical and surgical complications, postoperative stay in intensive care unit (ICU) and days of hospital stay, and mortality. RESULTS: A total of 31 males with a mean age of 71 years were operated on between January 2011 and August 2013. Mortality was 45% (a mortality of 61% in open surgery compared to 23% with EVAR, p = .06). Variables significantly associated with 30-day mortality were preoperative hypotension < 80 mmHg (p = 0.004), creatinine > 2.1 mg / dl (p = 0.018), and hemodynamic instability during surgery (p < 0.05), regardless of the surgical technique used. The average stay in the ICU was 10 days in open surgery versus 2 days for EVAR (p = 0.04). The average hospital stay was 19 days in open surgery versus 6.5 days for EVAR. CONCLUSIONS: EVAR for treatment of rAAA in this hospital has decreased morbidity and mortality rates, the average stay in ICU, and hospitalization stay

RESUMO

Introducción: La reparación endovascular de los aneurismas (EVAR) es una técnica cada vez más utilizada y que necesita evaluar sus resultados en cuanto a morbimortalidad y comportamiento del aneurisma. Pocos estudios señalan datos del comportamiento del saco aneurismático. Objetivo: Realizar un análisis de los cambios de diámetro del saco aneurismático después de EVAR. Material y métodos: Entre febrero de 2009 y febrero de 2012, tratamos mediante EVAR a 73 pacientes (77 procedimientos) con AAA y/o aneurismas ilíacos, seleccionados según edad (> 75 años) o riesgo quirúrgico. Todos fueron seguidos a 1, 6 y 12 meses y luego de forma anual mediante angio-TC. Analizamos los que tienen, al menos, una angio-TC al año realizada en el mismo hospital, en total 28 pacientes (100 angio-TC), excluyendo los pendientes del control anual, muerte y pérdidas, la mayoría por angio-TC realizadas en otro centro. Un único facultativo calculó las mediciones axiales bidimensionales en el mismo equipo informático. Se implantaron 4 dispositivos diferentes y se analizaron 8 Endurant, 11 Excluder, 8 Zenith y 1 Anaconda. Resultados: Obtuvimos en todos los pacientes reducción del saco aneurismático. La disminución media por tipo de endoprótesis ha sido: Endurant 10,6mm; Excluder 7,8mm; Zenith 7,83mm; Anaconda 1mm. Conclusiones: En este primer análisis, la técnica utilizada no se ha relacionado con roturas del aneurisma, así como la regresión del saco aneurismático está presente en todos los dispositivos de nuestro estudio, lo cual parece haber sido favorablemente influido por la nueva generación de materiales del injerto. La relación entre la morfología del aneurisma y los efectos a largo plazo sobre la endoprótesis aórtica está aún por determinar por lo cual debemos seguir analizando datos y resultados(AU)


Introduction: Endovascular aneurysm repair (EVAR) is an increasingly used technique, but its results need to be evaluated as regards morbidity, mortality and behavior of the aneurysm. There are few studies that examine the behavior of the aneurysm sac. Objective: To perform an analysis of the aneurysm sac changes after EVAR. Material and methods: Between February 2009-February 2012 a total of 73 patients, selected according to age (> 75 years) or surgical risk, received EVAR treatment for AAA and/or iliac aneurysms (77 procedures). All patients were followed up at 1, 6, 12 months, and then annually using CT angiography. Those patients who had at least one CT angiography at the end of one year and performed in the same hospital were analyzed. A total of 28 patients (100 AngioCTs) were included, and those still awaiting the 12 month follow up, deaths and losses (mainly performed in other AngioCT sites), were excluded. All axial measurements were made by the same practitioner and computer equipment. Four different devices (8 Endurant, 11 Excluder, Zenith 8 and 1 Anaconda) were implanted and analyzed. Results: A reduction in the aneurysm sac was observed in all patients. The average decrease by type of endoprosthesis was: Endurant 10.6mm, Excluder 7.8mm, Zenith 7.83mm, and Anaconda 1mm. Conclusions: In this first analysis, the technique has not associated with aneurysm rupture, and aneurysm sac reduction was present in all the devices studied, which seems to have been favorably influenced by the new generation of graft materials. The relationship between the morphology of the aneurysm and the long-term effects on aortic stents still has to be determined and we must continue to analyze the data and results(AU)

RESUMO

Introducción. La neuropatía, la isquemia y la infección son los tres factores directamente relacionados con la aparición y desarrollo de las úlceras en los pacientes diabéticos. La infección definida mediante parámetros clínicos y apoyada por cultivos microbiológicos es el principal factor pronóstico de la lesión. Objetivo. Estudiar la etiología infecciosa de las úlceras en pacientes diabéticos y no diabéticos, así como la sensibilidad in vitro a antimicrobianos de los microorganismos aislados, nos permitirá establecer la mejor pauta antibiótica empírica en nuestro medio asistencial. Pacientes y métodos. Estudio observacional, transversal y prospectivo de 200 pacientes consecutivos, diabéticos y no diabéticos, ingresados por la presencia de úlceras isquémicas o neuropáticas con signos locales de infección. Toma de tres muestras microbiológicas el día del ingreso previa administración del tratamiento empírico (ciprofloxacino + clindamicina) y valoración de su respuesta clínica y sus modificaciones a específico por resistencia de los microorganismos. Resultados. En la mayoría de los cultivos se aisló microbiota polimicrobiana con predominio de aerobios-anaerobios gramnegativos y aerobios grampositivos. Staphylococcus aureus (10,6%), Pseudomonas aeruginosa y Bacteroides fragilis fueron los microorganismos más frecuentemente aislados. La terapia empírica tuvo que modificarse en más del 50% de los casos por resistencia. La mayor sensibilidad in vitro para los microorganismos grampositivos fue para la vancomicina, seguida de cloxacilina y amoxicilina/clavulánico. En el caso de aerobios-anaerobios gramnegativos, fue para meropenem, tobramicina e imipenem, y para los anaerobios, imipenem, cefoxitina y amoxicilina/clavulánico. Conclusiones. La administración de amoxicilina/clavulánico solo o asociado a tobramicina constituye una pauta antibiótica con amplio espectro para los pacientes ambulatorios. En régimen de ingreso el antibiótico de elección sería imipenem, seguido de piperacilina/tazobactam


Introduction. Neuropathy, ischaemia and infection are the three factors directly related to the appearance and development of ulcers in diabetic patients. Infection defined by means of clinical parameters and backed up by microbiological cultures is the main prognostic factor of the lesion. Aims. To study the infectious causation of ulcers in diabetic and non-diabetic patients, in addition to the in vitro sensitivity to antimicrobials of the microorganisms that were recovered, in order to enable us to develop a better empirical antibiotic regimen in our health care area. Patients and methods. We conducted a prospective, cross-sectional, observational study involving 200 consecutive diabetic and non-diabetic patients who were admitted to hospital due to the presence of ischaemic or neuropathic ulcers with local signs of infection. Three microbiological samples were taken on the day of admission before administration of the empirical treatment (ciprofloxacin + clindamycin) and their clinical response and modifications in the specific due to resistance of the microorganisms were evaluated. Results. Polymicrobial microbiota were recovered from most of the cultures, with predominance of gram-negative aerobic-anaerobics and gram-positive aerobics. Staphylococcus aureus (10.6%), Pseudomonas aeruginosa and Bacteroides fragilis were the most frequently recovered micro-organisms. The empirical therapy had to be modified in over 50% of cases due to resistance. The highest sensitivity in vitro for the grampositive micro-organisms was to vancomycin, followed by cloxacillin and amoxicillin/clavulanic acid. In the case of gram-negative aerobic-anaerobics, it was found to be meropenem, tobramycin and imipenem, while the anaerobics were seen to be more sensitive to imipenem, cefoxitin and amoxicillin/clavulanic acid. Conclusions. Administration of amoxicillin/ clavulanic acid alone or in association with tobramycin constitutes a wide-spectrum antibiotic regimen for outpatients. If the patient is hospitalised, the preferred antibiotic would be imipenem, followed by piperacillin/ tazobactam

RESUMO

Objetivo. Determinar si el valor plasmático preoperatorio de diversos marcadores biológicos de inflamación –proteína C reactiva (PCR), leucocitos y fibrinógeno– se asocia a la mortalidad de los pacientes con rotura de aneurisma de aorta abdominal (AAA). Pacientes y métodos. Estudio prospectivo de 37 pacientes intervenidos quirúrgicamente de AAA roto. Se extrajo una muestra de sangre periférica a cada uno de ellos para el estudio preoperatorio de los biomarcadores de inflamación. Además, se recogieron datos correspondientes a variables clínicas pre, intra y postoperatorias. Para el análisis de los valores plasmáticos de PCR se utilizó un test convencional (Tina-Quant). Resultados. De los marcadores biológicos de inflamación estudiados, sólo la PCR fue un factor pronóstico de mortalidad perioperatoria, y la mediana fue significativamente superior en los fallecidos en comparación con los supervivientes (p=0,021). Se categorizó la PCR en dos grupos con la utilización como punto de corte el valor obtenido en la curva ROC (3,2 mg/dL) para la máxima sensibilidad y especificidad de esta variable con relación a la mortalidad. Los pacientes cuya PCR al ingreso fue >=3,2 mg/dL tuvieron una mortalidad significativamente mayor que aquellos cuya cifra era < 3,2 mg/dL (71 frente a 10%) (p=0,002). En el análisis multivariante, las variables pronósticas de mortalidad fueron: valor preoperatorio de PCR, duración del pinzamiento aórtico e inestabilidad hemodinámica durante la intervención. Conclusiones. La elevación de la PCR preoperatoria es un factor pronóstico de mortalidad en los AAA rotos, por lo que puede ser, junto a otros factores previamente identificados, útil para la estratificación del riesgo quirúrgico de estos pacientes


Aim. To determine whether the preoperative plasma values of several biological markers of inflammation –C-reactive protein (CRP), leukocytes and fibrinogen– are linked with the mortality of patients with a ruptured abdominal aortic aneurysm (AAA). Patients and methods. We performed a prospective study of 37 patients who had undergone surgery to treat a ruptured AAA. A peripheral blood sample was taken from each of the patients for use in the preoperative study of biomarkers of inflammation. Additionally, data concerning pre, intra and postoperative clinical variables were also collected. A conventional (Tina-Quant) test was used to analyse the CRP values in plasma. Results. Of the biological markers of inflammation studied, only CRP was a prognostic factor for perioperative mortality, and the mean was significantly higher in those who died than in survivors (p=0.021). CRP was categorised in two groups using a cut-off point taken as the value obtained from the ROC curve (3.2 mg/dL) for the maximum sensitivity and specificity of this variable in relation to mortality. Mortality among patients with a CRP on admission >=3.2 mg/dL was significantly higher than among those with a figure < 3.2 mg/dL (71 versus 10%) (p=0.002). In the multivariate analysis, the prognostic variables for mortality were: preoperative CRP value, duration of aortic clamping and haemodynamic instability during the intervention. Conclusions. Elevation of preoperative CRP levels is a prognostic factor for mortality in ruptured AAA, which means that, together with other previously identified factors, it may be useful for the stratification of surgical risk in these patients
