RESUMO

OBJECTIVE: Greater population life expectancy and consistent improvement in diagnostic techniques have increased the diagnosis of abdominal aortic aneurysms (AAAs) in the elderly population. The aim was to study the natural history of small (< 55 mm) incidental AAAs in octogenarian and nonagenarian patients to assess the need for follow up and/or invasive treatment. METHODS: This was a retrospective analysis of a prospective registry. Patients ≥ 80 years old at the time of diagnosis of a < 55 mm AAA in 1988-2018 were selected. Clinical and anatomical characteristics were registered. Patients were divided in three groups: 30 - 39 mm, 40 - 49 mm, and 50 - 54 mm AAA. The outcome variables were aorto-iliac rupture, AAA reaching a surgical threshold (≥ 55 mm), and death. A descriptive statistical analysis was performed and life tables, Kaplan-Meier curves, and uni- and multivariable Cox regression were used. RESULTS: Three hundred and ten patients were included, 256 (82.6%) men, with mean index age of 84.5 years (standard deviation [SD] 3.5), and median follow up of 37.9 months (interquartile range [IQR] 18.2 - 65.4). Eighteen (5.8%) AAAs ruptured; four of these patients were operated on and only one survived. Sixty-two (20%) AAA reached a surgical size; eight were repaired electively, with 0% early mortality. The survival rates were 81%, 70%, and 38% at one, two, and five years. The rupture rates were 1%, 2%, and 6% and the AAAs reaching surgical threshold were 1%, 4%, and 19% for the same time periods. AAA size < 40 mm was an independent protective factor from rupture (0.13; 95% confidence interval [CI] 0.03 - 0.48), reaching surgical threshold (0.08; 95% CI 0.04 - 0.16) and death (0.63; 95% CI 0.42 - 0.95). CONCLUSION: The risk of late rupture of small incidental AAA diagnosed in octogenarian and nonagenarian patients is very small, especially when the AAA is < 40 mm in diameter. In contrast, global mortality is high. Conservative management seems sensible, with strict selection of the patients who would benefit from follow up and eventual repair.

RESUMO

INTRODUCCIÓN Y OBJETIVOS: existen múltiples estudios sobre el pronóstico tardío de pacientes tras la reparación electiva de un aneurisma de aorta abdominal (AAA), pero escasos datos sobre aquellos que sobreviven a un AAA roto. El objetivo del presente estudio es analizar la supervivencia y los eventos cardiovasculares (eCV) que presentan estos pacientes a largo plazo. MATERIAL Y MÉTODOS: realizamos un análisis retrospectivo de una cohorte de pacientes supervivientes tras la reparación quirúrgica abierta de un AAA roto entre 1988 y 2014. Se incluyeron aquellos que habían sobrevivido al menos 3 meses tras la intervención y de los que teníamos un seguimiento clínico mínimo de un año. Se registraron los datos demográficos, los factores de riesgo cardiovascular, la comorbilidad, algunos detalles quirúrgicos, las muertes tardías y sus causas, los eCV y las complicaciones relacionadas con el injerto. Se analizaron las tasas de supervivencia y el tiempo libre de eventos cardiovasculares (TLECV), utilizando Kaplan-Meier y Mantel-Cox. RESULTADOS: se estudiaron 45 pacientes (42 hombres), con una edad media de 70 años (DS 8,3; rango 54-89) en el momento de la cirugía. El diámetro máximo medio de los AAA rotos era de 80,1 mm (DS 21,3; rango 51-135). El seguimiento medio fue de 7 años (DS 5,8; rango 0,3-21,5). 25 pacientes (55,6%) presentaron eCV tardíos: 13 cardiológicos (28,9%), 5 neurológicos (11,1%) y 8 vasculares periféricos (17,8%), con una tasa de 0,3 eventos/paciente-año (DS 1,7; rango 0-3,5). 26 pacientes (57,8%) fallecieron durante el seguimiento; los eCV fueron la causa más frecuente (n = 9; 20%). Las complicaciones relacionadas con el injerto fueron 3 (6,7%), con 2 muertes relacionadas (4,4%). La supervivencia de la cohorte a 2, 5 y 10 años fue de 86%, 66% y 53%, respectivamente, con tasas de TLECV de 79%, 65% y 40% para los mismos periodos. La edad y la cardiopatía aumentaron el riesgo de mortalidad y eCV, respectivamente (p ≤ 0,01). CONCLUSIONES: la supervivencia tardía tras superar la rotura de un aneurisma de aorta abdominal es buena, pero estos pacientes presentan una incidencia aumentada de eventos cardiovasculares a lo largo de su vida. Las complicaciones relacionadas con el injerto son poco frecuentes


INTRODUCTION AND OBJECTIVES: several studies have looked into the late prognosis of patients after elective abdominal aortic aneurysm (AAA) repair, but there is little data regarding those who survive a ruptured AAA. Our aim is to analyze the late survival and incidence of cardiovascular events in these patients. MATERIAL AND METHODS: we performed a retrospective analysis of a prospective cohort of patients who had survived the open repair of a ruptured AAA between 1988 and 2014. We included the patients who had survived at least 3 months after the procedure and of whom we had clinical follow-up of at least a year. We registered demographic data, cardiovascular risk factors, comorbidity, some surgical details, late deaths and their causes, cardiovascular events and graft-related complications. We analyzed the survival and freedom from cardiovascular event rates using Kaplan-Meier curves and Mantel-Cox regression. RESULTS: we studied 45 patients (42 men), with a mean age of 70 years (SD 8.3; range 54-89) at the time of the surgical repair. The maximum mean diameter of the ruptured AAA was 80.1 mm (SD 21.3; range 51-135). Mean follow-up was 7 years (SD 5.8; range 0.3-21.5). 25 patients (55,6%) suffered from late cardiovascular events: 13 cardiological (28.9%), 5 neurological (11.1%), and 8 peripheral vascular events (17.8%), with a rate of 0,3 events/ patient-year (SD 1.7; range 0-3.5). 26 patients (57.8%) died during follow-up, with cardiovascular events as the main cause (n = 9; 20%). There were 3 graft-related complications (6.7%), and 2 graft-related deaths (4.4%). The cohort's survival rates were 86%, 66% and 53% at 2, 5 and 10 years respectively, with freedom from cardiovascular evento rates of 79%, 65% and 40% for the same time periods. Age and cardiac disease increased the risk of late death and cardiovascular events respectively (p ≤ 0,01). CONCLUSIONS: late survival after successful open repair of a ruptured AAA is good, but these patients suffer an increased incidence of cardiovascular events throughout their lives. Graft-related complications are rare

RESUMO

Introducción. La amputación mayor por isquemia es una importante causa de discapacidad y genera un elevado coste sociosanitario. Objetivo. Hemos analizado los factores que influyen en la rehabilitación de los pacientes que previamente deambulaban y sufren una amputación mayor de causa isquémica. Pacientes y métodos. Realizamos 119 amputaciones mayores por causa isquémica en 105 pacientes con deambulación (entre enero de 2000 y diciembre de 2004). El grado de rehabilitación se valoró con el Walking Ability Index (WAI): 1-2: deambulación sin soporte; 3-5: deambulación con soporte; 6: no deambulación. Analizamos: la edad, el sexo, la obesidad, los factores de riesgo cardiovascular, la comorbilidad, el nivel de amputación, la biamputación y el apoyo familiar. Análisis estadístico: chi al cuadrado y t de Student. Resultados. De los 105 pacientes que iniciaron el programa de rehabilitación: 81 varones (77%), edad 72 ± 13 años (14-100), 14 biamputados (13,3%), 104 amputaciones supracondíleas y 15 infracondíleas. Seguimiento: 19,7 ± 16,1 meses (1,1-60). El 54,3% de estos pacientes consiguió una deambulación efectiva. La puntuación WAI obtenida fue: 1-2: 46 (43,8%); 3-5: 11 (10,5%); 6: 48 (45,7%). Influyeron negativamente en la rehabilitación: la edad ≥ 80 años (RR: 4,76; IC 95%: 1,8-12,2; p = 0,001), el sexo femenino (RR: 5,1; IC 95%: 1,8-14,2; p = 0,001), la amputación supracondílea frente a la infracondílea (RR: 5,5; IC 95%: 1,1-26,2; p = 0,019), la hemiplejía (RR: 3,48; IC 95%: 1,1-11,9; p = 0,038) y la carencia de apoyo familiar (RR: 7,23; IC 95%: 1,5-34,9; p = 0.005). Conclusiones. La mitad de los pacientes amputados por causa isquémica que inician un programa de rehabilitación consigue una protetización satisfactoria. El nivel infracondíleo obtiene altas tasas de deambulación. El apoyo familiar es muy importante. La edad elevada, el sexo femenino y el déficit neurológico previo son factores de mal pronóstico para conseguir la rehabilitación


Introduction. Ischemic major limb amputation causes significant disability and conveys high socio-sanitary costs. Aim.We have analysed the factors which influence the rehabilitation of previously ambulatory patients who suffer a major limb amputation because of peripheral arterial disease (PAD). Patients and methods. We performed 119 major limb amputations because of PAD in 105 previously ambulatory patients (January 2000-December 2004). The success rate of the rehabilitation program was assessed with the Walking Ability Index (WAI): 1-2: ambulation with no external support (crutches, canes); 3-5: ambulation with additional support; 6: no ambulation. We analysed: age, gender, obesity, cardiovascular risk factors, comorbidity, level of amputation, bilateral amputation and family support. Statistical analysis: chi-square, t-test. Results. From the 105 patients who started the rehabilitation program: 81 (77%) men, age 72 ± 13 years (14-100), 14 (13.3%) bilateral amputations; 104 above-knee amputations, 15 below-knee amputations. Follow-up: 19.7 ± 16.1 months (1.1-60). Satisfactory ambulation was achieved in 54.3% of the patients. We obtained the following WAI results: 1-2: 46 (43.8%); 3-5: 11 (10.5%); 6: 48 (45.7%). The factors which negatively influenced the rehabilitation process were: old age (≥ 80 years old) (RR: 4.76; IC 95%: 1.8-12.2; p = 0.001), female gender (RR: 5.1; IC 95%: 1.8-14.2; p = 0.001), above-knee vs. below-knee amputation (RR: 5.5; IC 95%: 1.1-26.2; p = 0,019), previous stroke (RR: 3.48; IC 95%: 1.1-11.9; p = 0.038) and lack of family support (RR: 7.23; IC 95%: 1.5-34.9; p= 0.005). Conclusions. Half of the patients who suffer a major limb amputation because of PAD and begin a rehabilitation program regain a satisfactory walking ability. Below-knee amputations achieve high ambulation rates. Family support is very important. Old age, female gender and previous neurological deficit are negative factors in the rehabilitation process

RESUMO

Introducción. Los aneurismas arteriales peripancreáticos representan un 3,5% de los aneurismas de arterias viscerales. Su importancia radica en su alta probabilidad de rotura y mortalidad, que puede llegar al 50%. Casos clínicos. Presentamos cuatro casos de patología arterial peripancreática complicada, tres hombres y una mujer, que se presentaron en nuestro servicio entre 1995 y 2005. En dos de los casos existían antecedentes de pancreatitis aguda complicada. La presentación clínica más habitual fue el dolor epigástrico agudo asociado, según el caso, a shock, hemorragia digestiva e incluso ictericia. El diagnóstico se realizó con tomografía axial computarizada y arteriografía selectiva de arteria mesentérica superior; se objetivaron dos aneurismas verdaderos y dos pseudoaneurismas en el caso de los pacientes con antecedentes de pancreatitis. Se optó por la embolización percutánea como primera opción terapéutica en todos los casos, aunque en dos de ellos fue necesario revertir a cirugía abierta y realizar una ligadura simple del vaso sangrante. Se excluyeron con éxito todos los aneurismas o pseudoaneurismas y no se observó ninguna recidiva. Durante el seguimiento, que ha sido de 11 años y 4 meses, dos pacientes precisaron un drenaje de los abscesos intraabdominales y uno falleció debido a una patología concomitante. Conclusiones. El tratamiento de primera elección en los aneurismas y pseudoaneurismas peripancreáticos rotos en la actualidad es la embolización endovascular. Cuando ésta no es eficaz o no está disponible, la exclusión quirúrgica se convierte en la alternativa adecuada


Introduction. Peripancreatic arterial aneurysms represent 3.5% of all aneurysms in visceral arteries. Their importance lies in the high likelihood of breakage and mortality rates, which can reach 50%. Case reports. We report four cases of complicated peripancreatic arterial pathology, three males and one female, who visited our service between 1995 and 2005. In two of the cases there was a history of complicated acute pancreatitis. The most frequent presenting symptom was acute epigastric pain associated with shock, digestive tract haemorrhage and even jaundice, depending on cases. The diagnosis was performed with computerised axial tomography and selective arteriography of the superior mesenteric artery; two true aneurysms and two pseudoaneurysms were found in the case of patients with a history of pancreatitis. Percutaneous embolisation was chosen as the first therapeutic option in all cases, although in two of them open surgery and simple ligation of the bleeding vessel had to be utilised. All the aneurysms or pseudoaneurysms were successfully excluded and no recurrences were observed. During the follow-up, which has lasted for 11 years and 4 months, intra-abdominal abscesses had to be drained in two of the patients and another died as a result of a concomitant pathology. Conclusions. The preferred treatment in cases of ruptured peripancreatic aneurysms and pseudoaneurysms today is endovascular embolisation. When this treatment is not effective or not available, surgical exclusion is a suitable alternative

RESUMO

Objetivo. Analizar nuestra experiencia en el tratamiento de la infección de la prótesis tras cirugía del sector aortoilíaco. Pacientes y métodos. Entre 1987 y 2005, 328 pacientes se sometieron a una reconstrucción mediante prótesis en el sector aortoilíaco. La cirugía por patología aneurismática se llevó a cabo en 303 pacientes (92,3%), y en 25 (7,7%) por patología obliterante de las extremidades inferiores. Durante este período, cinco pacientes (1,5%) presentaron infección protésica. Sexo: cuatro varones y una mujer; edad media: 67,9 años; tiempo medio de diagnóstico entre cirugía e infección: cuatro años. Hubo una infección precoz (20%) y cuatro tardías (80%); presentación clínica: fístula cutánea inguinal en tres pacientes (60%) y síndrome febril en dos (40%); diagnóstico: en dos pacientes mediante tomografía axial computarizada, en otros dos por gammagrafía con leucocitos, y en uno por fistulografía. El cultivo de prótesis fue positivo en dos pacientes (40%) para Escherichia coli y Candida krusei. El cultivo de exudado inguinal resultó positivo en tres pacientes (60%) para Staphylococcus. El tratamiento instaurado fue antibioterapia, seis semanas por vía intravenosa y posteriormente seis meses por vía oral, junto con la extracción de la prótesis infectada y la realización de una derivación extraanatómica. Resultados. La mortalidad precoz fue del 20%: un paciente falleció debido a un shock séptico. No hubó pérdidas de extremidad. Durante el seguimiento a largo plazo ninguno de los cuatro pacientes presentó nuevas complicaciones infecciosas. Conclusiones. El tratamiento mediante extracción de la prótesis, reconstrucción extraanatómica y tratamiento antibiótico prolongado constituye una opción adecuada en el tratamiento de esta grave complicación


Aim. To analyse our experience in the treatment of graft infections following surgery of the aortoiliac segment. Patients and methods. Between 1987 and 2005, 328 patients underwent reconstruction by means of a graft in the aortoiliac segment. Surgery was carried out due to aneurysmal pathologies in 303 patients (92.3%), and in 25 patients (7.7%) the intervention was required because of an obliterative pathology affecting the lower limbs. During this period five patients (1.5%) had infected grafts. Sex: four males and one female; mean age: 67.9 years; mean diagnosis time between surgery and infection: four years. One early (20%) and four late infections (80%) were observed; clinical presentation: inguinal cutaneous fistula in three patients (60%) and fever in two (40%); diagnosis: by means of computerised axial tomography in two patients, by leukocyte scintigraphy in two other cases and in one patient fistulography was used. The graft was culture-positive for Escherichia coli and Candida krusei in the case of two patients (40%). The inguinal exudate was culture-positive for Staphylococcus in three patients (60%). Antibiotherapy treatment was established for six weeks intravenously and then orally for six months; the infected graft was removed and an extraanatomical bypass was performed. Results. Early mortality rate was 20%, since one patient died due to septic shock. No extremities were lost. None of the four patients had any new complications involving infection throughout the long-term follow-up. Conclusions. Treatment by removal of the graft, extra-anatomical reconstruction and prolonged treatment with antibiotics is a suitable option for the treatment of this severe complication
