ABSTRACT

Introducción: Los aneurismas aórticos abdominales constituyen un problema de salud por la alta mortalidad que provocan. Su seguimiento y tratamiento son fundamentales para evitar las complicaciones posquirúrgicas. Objetivo: Caracterizar las principales complicaciones posquirúrgicas de los pacientes con aneurisma de la aorta abdominal operados electivamente. Métodos: Se realizó un estudio observacional y descriptivo en 94 pacientes operados de forma electiva en el Instituto Nacional de Angiología y Cirugía Vascular por presentar un diagnóstico de aneurisma de la aorta abdominal. Las variables de estudio fueron: edad, sexo, color de la piel, enfermedades asociadas, diámetro del aneurisma, profilaxis antibiótica, tiempo quirúrgico, tipo de prótesis vascular, tipo de complicación posoperatoria, tiempo de aparición de las complicaciones, estadía hospitalaria posoperatoria y estado al egreso. Se determinaron las frecuencias absolutas y relativas. Resultados: El 56,4 por ciento de los pacientes operados presentó algún tipo de complicación, las cuales fueron más frecuentes en el sexo masculino por encima de los 60 años. Las más predominantes resultaron la bronconeumonía (24,5 por ciento) y las arritmias cardíacas (20,8 por ciento). La proporción de complicaciones se mostró mayor en los pacientes con injertos bifurcados, así como en aquellos sin profilaxis y con un tiempo quirúrgico prolongado. Hubo mayor frecuencia de enfermedades cardiovasculares entre los fallecidos. Conclusiones: En los pacientes operados de forma electiva de aneurisma de la aorta abdominal predominaron las complicaciones respiratorias y cardiovasculares, estas últimas provocaron un aumento en la mortalidad(AU)


Introduction: Abdominal aortic aneurysms are a health problem because of the high mortality they cause. Their follow-up and treatment are essential to avoid post-surgical complications. Objective: Characterize the main post-surgical complications of patients with electively operated abdominal aortic aneurysm. Methods: An observational and descriptive study was conducted in 94 electively operated patients at the National Institute of Angiology and Vascular Surgery after having a diagnosis of abdominal aortic aneurysm. The study variables were: age, sex, skin color, associated diseases, aneurysm diameter, antibiotic prophylaxis, surgical time, type of vascular prosthesis, type of postoperative complication, time of onset of complications, postoperative hospital stay, and state at discharge moment. Absolute and relative frequencies were determined. Results: 56.4 percent of operated patients had some form of complication, which were more common in the males over 60 years. The most predominant complications were bronchopneumonie (24.5 percent) and cardiac arrhythmias (20.8 percent). The proportion of complications was shown to be higher in patients with forked grafts, as well as in those without prophylaxis and with prolonged surgical time. There was a higher frequency of cardiovascular diseases among the deceased patients. Conclusions: In patients electively operated of abdominal aortic aneurysm, there was a predominance of respiratory and cardiovascular complications, and the latter caused an increase in mortality(AU)

ABSTRACT

Introducción: Los aneurismas de aorta abdominal resultan dilataciones arteriales a dicho nivel. Su ruptura constituye uno de los principales riesgos y provoca la muerte del paciente, de ahí la importancia de tratarlos a tiempo. Las opciones actuales de tratamiento son la cirugía abierta y la reparación aneurismática endovascular; esta última representa la primera línea de tratamiento, por constituir una técnica mínimamente invasiva con bajas tasas de morbilidad y mortalidad. Objetivo: Evaluar el tratamiento endovascular del aneurisma de la aorta abdominal con endoprótesis percutáneas en pacientes cubanos. Métodos: Entre enero y abril de 2018 se realizó un estudio prospectivo, descriptivo y cualitativo en 6 pacientes del sexo masculino con aneurisma de aorta abdominal, seleccionados aleatoriamente, que cumplieron los criterios de uso de endoprótesis vasculares y estuvieron de acuerdo con realizar el proceder. Se colocaron 6 dispositivos en una sala de angiografía, y se utilizó en los pacientes anestesia general y guía fluoroscópica. Resultados: De forma satisfactoria fue posible el tratamiento endovascular por vía percutánea de los 6 pacientes seleccionados; solo 1 presentó una complicación menor y fue dado de alta a las 72 horas y el resto fue egresado en menos de 24 horas. Se logró implementar por vez primera en el país el sistema de cierre percutáneo Proglide sin complicaciones. Conclusiones: El tratamiento endovascular por vía percutánea de aneurismas de aorta abdominal con endoprótesis vasculares es una alternativa eficaz para la cirugía convencional en pacientes que cumplen los criterios de uso del dispositivo(AU)


Introduction: Abdominal aortic aneurysms are arterial dilations in that level. Their rupture is one of the main risks and it causes death in patients; that is why the importance of treating them early. Among the current treatment options are open surgery and endovascular aneurismal reparation, being the last one in the first line of treatment since it is a minimal invasive technique with low rates of morbidity and mortality. Objective: To evaluate the endovascular treatment of abdominal aortic aneurysm with percutaneous endoprosthesis in Cuban patients. Methods: It was conducted from January to April 2018 a retrospective, descriptive and qualitative study in 6 male patients with aneurysm of the abdominal aorta, selected randomly and who met the criteria of vascular endoprosthesis use and agreed with the performance of the procedure. Six devices were placed in an angiography room and it was used general anaesthetic and fluoroscopic guidance. Results: It was possible in a satisfactory way the endovascular treatment by percutaneous way in the six patients selected; just one presented a minor complication and he was discharged after 72 hours; and the rest were discharged in less than 24 hours. It was implemented for the first time in the country without complications the system of percutaneous closure called Proglide. Conclusions: Endovascular treatment by percutaneous way of abdominal aortic aneurysms with vascular endoprosthesis is an efficient alternative for conventional surgery in patients that met the criteria of use of the device(AU)

ABSTRACT

A doença de Behçet é uma doença sistêmica, multifatorial e autoimune com diversas manifestações clínicas, entre elas o acometimento vascular. Aneurisma de aorta associado a erosão de vértebra lombar é condição rara na literatura, existindo apenas quatro relatos de caso nas bases de dados da PubMed. O presente artigo relata o caso de paciente do sexo feminino com diagnóstico de Doença de Behçet de longa data e aneurisma sacular de aorta abdominal infrarrenal com erosão de vértebra lombar. O caso foi tratado por meio de técnica endovascular com colocação de endoprótese monoilíaca e enxerto fêmoro-femoral cruzado, devido a limitações anatômicas da bifurcação aórtica. O artigo aborda a raridade desse tipo de apresentação da doença e o desfecho do tratamento e apresenta revisão da literatura sobre esse tema


Behçet's disease is an autoimmune, multifactorial, systemic condition with several clinical manifestations, including vascular disorders. An aortic aneurysm with vertebral erosion is rare in association with this pathology and there are only four case reports listed on the PubMed database. This article reports the case of a female patient with a long-standing diagnosis of Behçet's Disease who developed a saccular infrarenal abdominal aortic aneurysm with lumbar vertebral erosion. Her surgical treatment consisted of endovascular repair with a monoiliac endoprosthesis and a femorofemoral crossover bypass, because of limitations imposed by the anatomy of the aortic bifurcation. This paper discusses the rarity of this presentation of the disease and treatment outcomes and offers a brief review of the relevant literature

ABSTRACT

As fístulas aorto-cava são entidades raras e de etiologia variada, estando frequentemente associadas a significativa morbimortalidade. Acredita-se que o aumento da tensão da parede nos grandes aneurismas resulte em reação inflamatória e aderência à veia adjacente, culminando na erosão das camadas aderidas e na formação da fístula. O tratamento cirúrgico convencional tem altas taxas de mortalidade. Embolia pulmonar paradoxal e o vazamento são complicações temidas do tratamento endovascular. O uso de oclusor vascular associado a endoprótese bifurcada é boa opção no tratamento do aneurisma de aorta abdominal com fístula aorto-cava


Aortocaval fistulae are rare entities with a variety of etiologies and are very often associated with significant morbidity and mortality. It is believed that increased tension in the walls of large aneurysms can cause an inflammatory reaction resulting in adhesion to the adjacent vein and culminating in erosion of the adherent layers and fistula formation. Conventional surgical treatment has high mortality rates. Paradoxical pulmonary embolism and endoleaks are the most concerning complications linked with endovascular treatment. Using a vascular occluder in combination with a bifurcated endograft is a good option for the treatment of an abdominal aortic aneurysm with aortocaval fistula

ABSTRACT

ABSTRACT Chronic periaortitis (CP) is an umbrella term used to describe a group of nosologically allied conditions that include idiopathic retroperitoneal fibrosis (Ormond's disease), inflammatory abdominal aortic aneurysm, and perianeurysmal retroperitoneal fibrosis. Retroperitoneal fibrosis encompasses a range of diseases characterized by the presence of a fibro-inflammatory tissue, which usually surrounds the abdominal aorta and the iliac arteries and extends into the retroperitoneum to envelop neighboring structures-ureters. Retroperitoneal fibrosis is generally idiopathic, but can also be secondary to the use of certain drugs, malignant diseases, infections, and surgery. Here we describe a 5 years follow up (2006-2011) of 5 patients admitted to our hospital with symptoms, laboratory, imaging and pathologic finding compatible with retroperitoneal fibrosis. We review our clinical course of our patient with respect to the literature.


RESUMO Periaortite crônica (PC) é um termo genérico usado para descrever um grupo de condições nosologicamente ligadas que incluem a fibrose idiopática retroperitoneal (doença de Ormond), o aneurisma da aorta abdominal inflamatório e a fibrose retroperitoneal perianeurismática. O termo fibrose retroperitoneal engloba uma gama de doenças que se caracterizam pela presença de um tecido fibroinflamatório que geralmente envolve a aorta abdominal e as artérias ilíacas, se estende ao retroperitôneo e envolve estruturas ureterais vizinhas. A fibrose retroperitoneal geralmente é idiopática, mas pode também ser secundária ao uso de determinados fármacos, doenças malignas, infecções e cirurgia. Este estudo descreve o seguimento por cinco anos (2006-2011) de cinco pacientes internados em nosso hospital que apresentavam sintomas e achados laboratoriais, de imagem e patológicos compatíveis com a fibrose retroperitoneal. Revisou-se a evolução clínica dos pacientes, que foi comparada com os achados da literatura.

ABSTRACT

Paciente masculino, 57 anos, hipertenso, etilista, ex-tabagista, com quadro anterior de acidente vascular encefálico por aneurisma em artéria cerebral média em 1998. No ano de 2013, com sintomas de cansaço e mialgias, pensava estar com dengue, não suportando ficar de pé devido às dores em membros inferiores. Concomitantemente, apresentou paralisia facial central e perda da força motora em membro inferior direito, sendo internado com diagnóstico de acidente vascular encefálico isquêmico. Constatou-se também isquemia subepicárdica lateral alta ao eletrocardiograma, apesar de o paciente se apresentar oligossintomático sob o ponto de vista cardiovascular, sendo submetido a diversas investigações angiográficas e angiotomográficas, possibilitando o diagnóstico do aneurisma de aorta abdominal infrarrenal silencioso. As inespecificidades e o quadro clínico assintomático da doença são dificuldades comumente encontradas no diagnóstico, tornando-se fundamental a utilização de técnicas complementares de alta complexidade para definição do diagnóstico por imagem. São essenciais as atualizações e pesquisas sobre o presente tema, aumentando a acurácia e a precocidade do diagnóstico, e diminuindo, portanto, a morbimortalidade dos pacientes portadores de aneurisma de aorta abdominal.


Abdominal aortic aneurysm (AAA) is an irreversible aortic dilatation below renal arteries, usually, asymptomatic, showing high morbidity and mortality, becoming relevant this clinical report. Abdominal aortic aneurysm is particularly difficult to diagnose. This study aims to describe in detail the diagnostic process in several levels: syndromic functional, anatomical and etiological and commonly difficulties encountered. Male, 57 year-old, hypertensive, alcoholic and smoker with a previous history of stroke due to middle cerebral artery aneurysm in 1998. In the year 2013 with symptoms of fatigue and muscle pain, thought to have dengue, he wasn't supporting to stand up due to a pain in the lower limbs (LL). Simultaneously he suffered central facial paralysis and loss of motor strength in the right leg. Therefore he was hospitalized with a diagnosis of a new stroke. He showed also high lateral subepicardial ischemia on electrocardiogram, although he had a few atipical cardiovascular symptoms. The patient was submitted to diverse angiographic and angiotomographies investigations, allowing the precise diagnosis of a silent infrarenal Abdominal aortic aneurysm . The authors present a clinical case of infrarenal Abdominal aortic aneurysm, reporting diferentt clinical procedures. The report also discusses the endovascular therapeutic approach and the clinical screening and diagnostic methods. The unspecific and asymptomatic clinical picture of this disease were commonly found difficulties in diagnosis, becoming essential the use of complementary techniques of high definition for diagnostic imaging. Updates are required and research on this topic increasing the accuracy for an early diagnosis and treatment, reducing therefore the morbidity and mortality of these patients.

ABSTRACT

OBJECTIVES: To analyze angiotomographic parameters of juxtarenal aneurysms to assess the applicability of an endograft model to patients and to create in vitro and in vivo models to assess the new endograft. METHODS: A total of 49 patients with juxtarenal aneurysms were submitted to angiotomographic evaluation, and parameters such as the aortic diameter, the length of the neck, and the angulations of the celiac trunk, superior mesenteric artery and renal arteries; the distances between them; and anatomic variations were analyzed. Based on these parameters, an endograft model was developed and tested in a newly created in vitro model of juxtarenal aneurysm. An experimental model of juxtarenal aneurysm was then established in six pigs weighing 50-60 kg to assess the new endograft model. RESULTS: The angiotomographic parameters of juxtarenal aneurysm measured in this study were similar to those reported in the literature and allowed the development of an endograft based on the hourglass concept, which was applicable to 85.8% of the patients. The in vitro model of juxtarenal aneurysm evidenced good radiopacity and functionality and permitted adjustments in the new device and technical improvements in the procedures for treating these aneurysms. In addition, the porcine model of juxtarenal aneurysm was successfully created in all six animals using a bovine pericardial patch, and use of the new endograft in three pilot procedures evidenced its feasibility. CONCLUSIONS: The Hourglass endograft was rendered applicable to treatment of the majority of patients with juxtarenal aneurysms simply by changing its diameter. Moreover, the new in vitro and in vivo models were shown to be effective for assessing both the presented endograft and experiments assessing the endovascular treatment of juxtarenal aneurysms. .

ABSTRACT

Los aneurismas toracoabdominales son poco frecuentes; según la literatura su incidencia es de 1 por cada 100.000 personas siendo esto estimado en la incidencia de los aneurismas abdominales 1-3%. La edad media de aparición es de 65 años y en su mayoría la principal causa es de enfermedad aterosclerótica. La clasificación de los aneurismas toracoabdominales es en base a la que describió Crawford: Tipo I- Tipo IV. En la Unidad de Cirugía Cardiovascular de Guatemala se trató un caso de un paciente joven con un aneurisma toracoabdominal según la clasificación de Crawford Tipo III.


Thoracoabdominal aneurysms are a rare disease; according to the literature the incidence is 1 per 100,000people this being estimated incidence of abdominal aneurysms 1-3%. The average age of onset is 65 yearsold and mostly the main cause is atherosclerotic disease. The classification of thoracoabdominal aneurysms isbased on that described Crawford: Type I-Type IV. In the Unidad de Cirugía Cardiovascular de Guatemala acase of a young patient with thoracoabdominal aneurysm was treated as classified by Crawford type III.

ABSTRACT

Primary aortoenteric fistula (PAEF) is a rare but catastrophic cause of massive gastrointestinal bleeding. Diagnosis of PAEF is difficult to make and is frequently delayed without strong clinical suspicion. Timely surgical intervention is essential for patient's survival. We report on a case of an 86-year-old woman with no history of abdominal surgery, who presented with abdominal pain. Initially, computed tomography scan showed an intra-abdominal abscess, located anterior to the aortic bifurcation. However, she was discharged without treatment because of spontaneous improvement on a follow-up computed tomography scan, which showed a newly developed right common iliac artery aneurysm. One week later, she was readmitted due to recurrent abdominal pain. On the second day of admission, sudden onset of gastrointestinal bleeding occurred for the first time. After several endoscopic examinations, an aortoenteric fistula bleeding site was found in the sigmoid colon, and aortography showed progression of a right common iliac artery aneurysm. We finally concluded that intra-abdominal abscess induced an infected aortic aneurysm and enteric fistula to the sigmoid colon. This case demonstrated an extremely rare type of PAEF to the sigmoid colon caused by an infected abdominal aortic aneurysm, which has rarely been reported.

ABSTRACT

BACKGROUND/AIMS: Recurrence of ischemic colitis (IC) has not been studied extensively. The aim of this study was to investigate the characteristics of recurrent IC in the community setting and to identify any risk factors. METHODS: We conducted a retrospective study in two community hospitals. Medical records of patients with IC from January 2007 to January 2013 were reviewed. Demographic details, clinical features, co-morbidities, concomitant use of medications, laboratory studies, imaging findings, endoscopic and histological features, surgery, hospital stay, and death within 30 days were collected. Patients were divided into two groups (recurrent IC group, non-recurrent IC group). RESULTS: A total of 118 patients with IC were identified. IC recurred in 10 patients (8.5%) during the study period. Half of the patients in the recurrent IC group were current smokers as compared to only 18.7% of patients in the non-recurrent group. In the recurrent IC group, 20.0% of patients never smoked as compared to 61.7% in the non-recurrent group (p=0.027). Abdominal aortic aneurysm (AAA) was more frequent in the recurrent IC group (40.0% vs. 4.7%; p=0.003). No differences in other clinical symptoms, CT scan findings, comorbidities, endoscopic features, or use of concomitant medications were observed between the two groups. The need for surgical intervention, blood transfusion, intensive care unit stay, mechanical ventilation, length of hospital stay, and anatomic location of affected segments did not differ between the two groups. CONCLUSIONS: IC recurred in 8.5% of patients during the six-year study period. Current smoking status and presence of AAA were identifying risk factors for recurrence of IC.

ABSTRACT

BACKGROUND:Diagnosis of abdominal aortic aneurysm (AAA) is usually incidental, and surgical treatment, when indicated, may be open or endovascular. The drawbacks of computed angiotomography (CTA) and the advantages of Doppler ultrasonography have led to the development of alternative follow-up protocols, comparing the two methods. OBJECTIVE: To determine validity indices for Doppler ultrasonography and to correlate them with CTA results in a group of patients who had undergone elective endovascular treatment of AAAs. MATERIAL AND METHODS: Thirty-three patients were selected. The following three items were evaluated: 1) presence or absence of endoleak; 2) presence of blood flow in the aortoiliac segment; and 3) maximum AAA diameter. RESULTS: For the detection of endoleak, Doppler ultrasonography showed a sensitivity of 54.5%, a specificity of 92.8%, a positive predictive value of 85.7%, a negative predictive value of 92.8%, and an overall accuracy of 76%. For the evaluation of blood flow in the aortoiliac segment, values were 100, 97.8, 80, 97.8, and 98%, respectively. Maximum AAA diameter was similarly measured by both methods, with statistically significant differences (mean difference: 1.98 mm). Pearson's correlation coefficient was 0.97, showing that Doppler ultrasonography and CTA yielded similar results. CONCLUSION: Doppler ultrasonography showed good validity indices and a moderate correlation with CTA in the postoperative evaluation of patients undergoing endovascular treatment of AAAs. .

ABSTRACT

Primary aortoenteric fistula (PAEF) is a rare disease with a high mortality rate due to massive hemorrhaging and diagnostic difficulties. Although hemorrhagic regions can be identified by endoscopy, it is difficult to diagnose PAEF by this method. If PAEF is suspected, endoscopic procedure should be terminated and abdominal CT should be performed. Overlooking the herald bleeding of PAEF can lead to massive bleeding and death. An 85-year-old previously healthy male presented with a complaint of melena. Gastrointestinal endoscopy identified a hemorrhagic site in the third portion of the duodenum and endoscopic hemostasis was performed. However, during the procedure, it became apparent that the hemorrhage was probably not the result of a simple duodenal ulceration and abdominal CT was performed immediately. An aortic aneurysm connected to the duodenum was identified, confirming the diagnosis of PAEF. However, the patient died of massive hemorrhaging before an operation could be performed.

ABSTRACT

PURPOSE: It is important to know the normal diameter of artery throughout the body so that clinicians are able to determine when an artery becomes aneurysmal. However, there are no previous studies on the normal diameter of arteries in the general Korean population. The purpose of this article is to determine the normal reference diameters of the abdominal aorta and iliac arteries in the Korean population. MATERIALS AND METHODS: We recruited the study population from three cities in Korea for the abdominal aortic aneurysm (AAA) screening. We measured the diameter of the aorta and iliac arteries. We analyzed the reference diameter of the population without AAA. The results were analyzed by Student's t-test and ANOVA on SPSS version 19. A p value <0.05 was considered to be statistically significant. RESULTS: One thousand two hundred and twenty-nine people were enrolled. 478 men and 751 women, with a mean age of 63.9+/-10.1 years (range 50 to 91) were examined. Eleven out of 1229 (0.89%) were diagnosed with AAA. In the population of 1218 people without AAA, the mean diameters (cm) of male/female were 2.20/2.11 (p<0.001) at suprarenal, 2.04/1.90 (p<0.001) at renal, 1.90/1.79 (p<0.001) at infrarenal, 1.22/1.17 (p<0.001) at right iliac and 1.47/1.15 (p=0.097) at the left iliac, respectively. There was a significantly larger diameter in the male population. The diameter of each level increased with age. CONCLUSION: The normal reference diameter of the infrarenal abdominal aorta in the Korean population is 1.9 cm in males and 1.79 cm in females. The diameter of the abdominal aorta increases with age.

ABSTRACT

Antecedentes: El propósito de este estudio es comparar la morbilidad y la mortalidad tanto de la reparación abierta (RA) como endovascular de la ruptura del aneurisma aórtico abdominal(rAAAs); y de presentar un algoritmo para el tratamiento y evaluaciones de la tomografía computarizada (CT) para determinar el uso de un balón oclusivo supra-celíaco. Métodos: Una revisión gráfica retrospectiva se realizó de los rAAAs tratados ya sea con reaparicióna cielo abierto (RA), ya sea con reparación aórtica endovascular (EVAR) entre junio de 1998 y junio de 2009. Se informaron las co-morbilidades, los datos peri-procedimientos y tanto la morbosidad como la mortalidad. Las TC se revisaron desde el uso inicial del balón oclusivo (Marzo de 2001) a fin de evaluar el hematoma retroperitoneal. Se desarrolló un algoritmo para determinarcuándo el balón oclusivo se debería implementar. El test exacto de Fisher, el t-test, y el test log rank fueron los que se utilizaron para el análisis estadístico.Resultados: Entre junio de 1998 y junio de 2009, 105 pacientes, 75 (71.4%) hombres, edad promedio de 74 años (rango 47-93) presentaron un rAAA y a 69 (65.2%) se les realizó la reparación a cielo abierto. 87 pacientes (82.9%) fueron sintomáticos y 25 (23.8%) tenían un AAA conocido. El tiempo medio transcurrido entre el diagnóstico y el tratamiento fue de 5 a 6 horas, 4.5 horas para la RA y de 8 horas para EVAR. El test rank log mostró una mejoría en la supervivencia con EVARa pesar del tiempo promedio más prolongado desde el diagnóstico al tratamiento. (p=0.02). Se administraron casi tres veces más concentrados de hematíes en el cohorte de reparación a cielo abierto (RA), 6.3 unidades y en EVAR 2.2 unidades. Se utilizaron vasopresores perioperatorios en el 57.1% de los casos, dos veces más en la RA, 69.6%, que con EVAR 33.3%. Se utilizó el balón oclusivo aórtico en el 27,6% de los casos, dos veces más frecuente en RA que en EVAR (41,7% verus 20,3%)...


Antecedentes: O propósito deste estudo é comparar a morbilidade e a mortalidade tanto da reparação aberta (RA) quanto endovascular, utilizadas no tratamento da ruptura do aneurisma aórtico abdominal (rAAAs); e de apresentar um algorítmo para o tratamento e avaliações da tomografiacomputarizada (CT) para assim determinar o uso de um balão para oclusão supra-celíaca. Métodos: Realizou-se uma revisão gráfica retrospectiva das rAAAs tratadas, seja com reparação a céu aberto (RA), ou com reparação aórtica endovascualar (EVAR) entre os meses de junho de1998 e junho de 2009. Informaram-se as comorbilidades, os dados periprocedimentos , além da morbidade e mortalidade. As TC foram revisadas desde o uso inicial do balão oclusivo (março de 2001) com o objetivo de avaliar o hematoma retroperitoneal. Desenvolveu-se um algorítmo para determinar quando o balão oclusivo deveria ser implementado. Para esta análise estatística, utilizaram-se o teste exato de Fisher, o t-test, e o test log Rank. Resultados: Entre junho de 1998 ejunho de 2009, 105 pacientes, 75 (71.4%) homens, com média de idade de 74 anos (média 47-93) apresentaram uma rAAA e em 69 (65.2%) realizou-se uma reparação a céu aberto. 87 pacientes (82.9%) foram sintomáticos e 25 (23.8%) tinham um AAA conhecido. O tempo médio transcorrido entre o diagnóstico e o tratamento foi de 5 a 6 horas, 4.5 horas para a RA e de 8 horas para aEVAR. O test rank log mostrou uma melhoria na sobrevivência com a EVAR, apesar do tempo médio mais prolongado do diagnóstico ao tratamento. (p=0.02). Administraram-se quase três vezes mais concentrados de hematies no grupo de reparação a céu aberto (RA), 6.3 unidades e no grupo EVAR, 2.2 unidades. Utilizaram-se vasopressores perioperatórios em 57.1% dos casos: 33.3% com EVAR e 69.6% com a RA, ou seja, duas vezes a mais. Utilizou-se o balão oclusivo aórtico em 27.6 % dos casos, duas vezes mais frequente nos casos da RA do que nos de EVAR (41.7 % versus 20.3%)...


Background: The purpose of this study is to compare morbidity and mortality of open and endovascular repair of ruptured abdominal aortic aneurysms (rAAAs); and present a treatment algorithm and assessment of computer tomography (CT) to determine usage of a supra-celiac occlusive balloon.Methods: Restrospective chart review was done of rAAAs treated with open (OR) or endovascular aortic repair (EVAR) between June 1998 and June 2009. Comorbidities, periprocedural data, and postoperative morbidity and mortality were recorded. CTs were reviewed from the initial use of the occlusive balloon (March 2001) to assess the retroperitoneal hematoma. An algorithm was developed determining when the occlusive balloon should be implemented. Fisher’s exact test, and log rank test were used for statistical analysis. Results: Between June 1998 and June 2009, 105 patients, 75 (71.4%) males, mean age of 74.0 years (range 47-93), presented with a rAAA and 69 (65.2%) received open repair. Eighty-seven patients(82.9%) were symptomatic and 25 (23.8%) had a known AAA. Mean time elapsed between diagnosis to treatment was 5.6 hours, 4.5 hours for OR and 8.0 hours for EVAR. Log rank test showsimproved survivability with the EVAR despite higher mean time from diagnosis to intervention (p=0.02). Nearly three times as much packed red blood cells were given in open repair cohort, O,6.3 units and EVAR, 2.2 units. Perioperative vasopressors were used in 57.1% of total cases, more than 2 times as often for O, 69.6%, and EVAR, 33.3%. Aortic occlusive balloon was used in 27.6% of cases, twice as often in EVAR (41.7% versus 20.3%)...

ABSTRACT

Uma das complicações mais temidas na cirurgia vascular é a infecção do enxerto sintético. Afeta 2 por cento dos procedimentos cirúrgicos convencionais e 0,3 a 6 por cento dos procedimentos endovasculares. Relatamos o caso de paciente tratada de aneurisma de aorta abdominal por ambos os métodos e que, após seis anos, foi submetida a retirada das próteses devido à infecção. A veia femoral superficial bilateral foi usada como substituto, com sucesso.


One of the most feared complications in vascular surgery is the infection of synthetic graft. It affects 2 percent of conventional surgery procedures and about 0.3 to 6 percent of endovascular procedures. We report the case of a patient treated for abdominal aortic aneurysm with both methods; after six years, this patient had the prosthesis removed because of infection. Bilateral superficial femoral vein were used as substitute with success.
