ABSTRACT

Abstract Takayasu's arteritis is a type of primary systemic vasculitis that affects medium and large arteries, including the aorta and its main branches, as well as the pulmonary and coronary arteries. Although rare in children, it is the third most common vasculitis in the pediatric population, often with delayed diagnosis due to the nonspecific presentation of clinical symptoms in its initial phase. This is a case of a 16-year-old girl with a giant ruptured abdominal aortic aneurysm, who needed surgery on an emergency basis. The etiological aspects involved in aneurysms in young patients are also addressed.

ABSTRACT

Se describe el caso clínico de una paciente de 4 años de edad, quien ingresó en el Servicio de Terapia Intensiva del Hospital Infantil Docente Sur Dr. Antonio María Béguez César de Santiago de Cuba por presentar dolor abdominal intenso, vómitos sanguinolentos, distención abdominal, tumoración palpable en el epigastrio, palidez cutáneo - mucosa, polipnea, taquicardia, hipotensión y trastornos de perfusión periférica, con evolución rápida y progresiva hacia un cuadro de insuficiencia multiorgánica y estado de choque. Los estudios clínicos e imagenológicos confirmaron el diagnóstico de aneurisma de aorta abdominal. A pesar de la atención médica intensiva, la evolución fue desfavorable.


The case report of a 4 years patient is described. She was admitted to the Intensive Therapy Service of Dr. Antonio María Béguez César Southern Teaching Pediatric Hospital in Santiago de Cuba due to an intense abdominal pain, bloody vomits, abdominal strain, palpable tumor in the epigastrium, cutaneous - mucous paleness, polipnea, tachycardia, hypotension and perypheral perfusion disorders, with quick and progressive clinical course toward a picture of multiorganic failure and state of shock. The clinical and imaging studies confirmed the diagnosis of abdominal aorta aneurysm. In spite of the intensive medical care, there was an unfavorable clinical course.

ABSTRACT

SUMMARY OBJECTIVE: We aimed to demonstrate the clinical utility of CHA2DS2-VASc and anticoagulation and risk factors in atrial fibrillation risk scores in the assessment of one year mortality in patients with abdominal aortic aneurysm. METHODS: We designed a retrospective cohort study using data from Suleyman Demirel University Hospital for the diagnosis of abdominal aortic aneurysm. The study included 120 patients with abdominal aortic aneurysm who underwent aortic computed tomography. Patients were divided into two groups according to presence of abdominal aortic aneurysm and the development of mortality. Predictors of mortality were determined by multiple logistic regression analysis. RESULTS: Multivariate regression analysis showed that CHA2DS2-VASc score, advanced age, female gender and elevated white blood cell counts were independent predictors of abdominal aortic aneurysm development while CHA2DS2-VASc score and elevated glucose levels were independent predictors of one year mortality in patients with abdominal aortic aneurysm. The concordance statistics for anticoagulation and risk factors in atrial fibrillation risk Score and CHA2DS2-VASc risk score respectively were 0.96 and 0.97 and could significantly predict one year mortality in patients with abdominal aortic aneurysm (p<0.001, and p<0.001, respectively). CONCLUSIONS: CHA2DS2-VASc and anticoagulation and risk factors in atrial fibrillation risk scores are easily obtained in an emergency setting and can accurately predict one year mortality as a noninvasive follow-up in patients with abdominal aortic aneurysm. These simple scores could be used as a point of care decision aid to help the clinician in counseling patients presenting with abdominal aortic aneurysm and their families on treatment protocols.

ABSTRACT

OBJECTIVES: This study aimed to determine the prevalence of signs of impending rupture (SIR) in asymptomatic patients with abdominal aortic and iliac artery aneurysms, and to evaluate whether these signs were associated with rupture in asymptomatic patients. METHODS: This was a retrospective study of patients with abdominal aortic and iliac artery aneurysms identified on computed tomography (CT) over a 10-year period in a single center. The CT scans were reviewed by two reviewers, and patients with SIR were assigned to one of three groups: (1) early symptomatic (ES), (2) late symptomatic (LS), and (3) always asymptomatic (AA). The four main SIR described in the literature were investigated: 1) crescent sign, 2) focal wall discontinuity of circumferential calcifications, 3) aortic bulges or blebs, and 4) aortic draping. RESULTS: From a total of 759 aortic and iliac aneurysm reports on 2226 CT scans, we identified 41 patients with at least one SIR, and a prevalence of 4.14% in asymptomatic patients. Focal wall discontinuity of circumferential calcifications was the most common sign, and it was present in 46.3% of these patients (19/41); among these, 26 were repaired (ES: 9, LS: 2, AA: 15). Eleven asymptomatic patients underwent follow-up CT. The aneurysm increased in size in 6 of the 11 (54.5%) patients, and three ruptured (all with discontinuity of calcifications), one of which had no increase in diameter. CONCLUSIONS: The presence of focal wall discontinuity of circumferential calcifications was the most common SIR. There was a prevalence of all signs in less than 5% of asymptomatic patients. In unrepaired patients, the signs could be observed on follow-up CT scans with an increase in aneurysm size, indicating that the presence of SIR alone in the absence of other clinical factors or aneurysm characteristics is an insufficient indication for surgery.

ABSTRACT

RESUMEN Introducción: la incorporación de la ecografía a los métodos diagnósticos de los aneurismas aórticos abdominales favorece su detección precoz. Objetivo: Describir las características de los pacientes a quienes se les detectó precozmente un aneurisma aórtico abdominal. Métodos: Estudio descriptivo de corte transversal en 243 pacientes pertenecientes al área de salud del Hospital Clinicoquirúrgico "General Freyre de Andrade", clasificados como población de riesgo (hombres > 50 años y mujeres > 60 años). El periodo de estudio: noviembre de 2016 a octubre de 2017. Resultados: Se realizó el diagnóstico de aneurisma aórtico abdominal en 2,1 % (n= 5); en estos pacientes prevaleció el grupo de edad de 70 a79 años (80 %) y el sexo masculino (60 %). Los factores de riesgo predominantes fueron el tabaquismo, la hipertensión arterial y la enfermedad arterial periférica, todos con igual porcentaje (100 %). El segmento aórtico más afectado fue el infrarrenal (100 %), los diámetros aórticos predominantes fueron: transversal (3-3,9 cm), longitudinal (5-10 cm) y antero-posterior (3-3,9 cm). La proteína C reactiva estuvo incrementada (mayor de 5 mg/L) en el 100 % de los casos. La claudicación intermitente fue la más frecuente. Conclusiones: A pesar de la baja prevalencia porcentual encontrada, destaca en todos los pacientes con aneurisma aórtico abdominal la presencia de factores de riesgo relevantes como es el tabaquismo, la hipertensión arterial y la enfermedad arterial periférica; incremento en la concentración de la proteína C reactiva, afectación en el segmento infrarrenal así como alto porcentaje con edades por encima de 70 años.


ABSTRACT Introduction: The incidence of abdominal aortic aneurysms in the population benefits from the incorporation of ultrasound to diagnostic methods due to the importance of their early detection. Objective: To describe the characteristics of patients who are early detected with an abdominal aortic aneurysm. Method: A descriptive, cross-sectional study was conducted in 243 patients belonging to the health area of "General Freyre de Andrade" Clinical- Surgical Hospital that were classified as a risk population (men > 50 years and women > 60 years). The study was conducted from November 2016 to October 2017. Results: The diagnosis of abdominal aortic aneurysm was performed in 2.1 % (n= 5); in these patients predominated the age group of 70 to 79 years (80 %), male sex (60 %) and white skin color (80 %). The predominant risk factors were smoking habit, arterial hypertension and peripheral arterial disease; all with equal percentage (100 %). The most affected aortic segment was the infrarenal (100 %), the predominant aortic diameters were: transversal (3-3.9 cm), longitudinal (5-10 cm) and anterior-posterior (3-3.9 cm). The C-reactive protein increased (greater than 5 mg/L) in 100 % of the cases. Intermittent claudication was the most frequent. Conclusions: Although the percentage prevalence of the disease was low, it was present in all the patients with abdominal aortic aneurysm, risk factors that are favorable to aneurysms, high concentrations of C-reactive protein, affectation in the infrarenal aortic segment, and high percentage of ages of more than 70 years.

ABSTRACT

ABSTRACT Endovascular aneurysm repair is an established technique for treating many infrarenal aortic aneurysms. Infection is one of the most serious complications of this technique, and although percutaneous treatment has been well established for intra-abdominal collections, its use to treat peri-prosthetic fluid collections has not been well determined. In this article we describe a small series of three patients who were treated with percutaneous drainage, with good clinical and imaging responses. Percutaneous drainage is a safe, effective and minimally invasive approach for treating this potentially fatal complication.


RESUMO O reparo endovascular de aneurisma é uma técnica para tratamento de diversos aneurismas infrarrenais da aorta. A infecção é uma das complicações mais sérias desse tratamento, e a abordagem percutânea tem sido adotada para coleções intra-abdominais, mas seu uso para tratamento de coleções protéticas vasculares não está bem estabelecido. Descreve-se, neste trabalho, pequena série de três pacientes tratados com drenagem percutânea, que apresentaram boa resposta clínica e de imagem. A drenagem percutânea mostrou-se abordagem segura, efetiva e minimamente invasiva para tratamento desta complicação, que é potencialmente fatal.

ABSTRACT

SUMMARY Point-of-care ultrasonography, which is performed at the bedside by physicians who are not specialists in imaging, has become possible thanks to recent technological advances that have allowed for a device with greater portability while maintaining image quality. The increasing use of point-of-care ultrasonography in different specialties has made it possible to expand physical examinations, make timely decisions about the patients and allows the performance of safer medical procedures. In this review, three cases from our experience are presented that highlight the use of point-of-care ultrasonography by clinicians. Bedside ultrasonography is a convenient modality used in a clinical setting to aid in early diagnosis of several common conditions. It is suggested that a hybrid approach of physical examination and point-of-care ultrasonography in the everyday clinical practice is an inevitable change of paradigm that is improving quality of care in a variety of clinical settings.

ABSTRACT

Resumen Objetivo: Revisión y análisis de la disección aórtica (DA) en la población mexicana. Método: Revisión retrospectiva de 434 expedientes electrónicos de pacientes con angiotomografía de aorta entre noviembre de 2014 y octubre de 2015. Se obtuvo una muestra de 32 pacientes con diagnóstico de DA de primera vez. Se realizó un análisis de las DA según género, grupo etario, clasificación de Stanford/De Bakey y mortalidad a 6 meses del diagnóstico. Se realizó análisis de significación estadística mediante la Chi-cuadrada para las variables independientes de género, síndrome de Marfan, hipertensión arterial sistémica y enfermedad ateromatosa calcificada en asociación con subtipos, sitios de reentrada y datos de hipoperfusión. Resultados: El 65.6% de los pacientes fueron masculinos, con un promedio de edad de 54.5 años, y el 34.4% fueron femeninos, con un promedio de edad de 42.5 años. El subtipo B/3 fue el más frecuentemente diagnosticado. La tasa de mortalidad a 6 meses fue del 18.7%. Se halló asociación significativa con p marginal en pacientes con síndrome de Marfan y subtipos de DA según Stanford (p = 0.0506), así como asociación significativa en pacientes con aneurisma de aorta abdominal y subtipos de DA según Stanford (p = 0.047104). Conclusiones: La DA es una emergencia en la cual el diagnóstico por imagen y el manejo oportuno son fundamentales para mejorar el pronóstico. En nuestra muestra encontramos asociación significativa de pacientes con antecedente de síndrome de Marfan y aneurisma aórtico abdominal con disecciones según la categoría de Stanford. El resto de las variables independientes no mostraron asociación significativa, en probable relación con el tamaño de la muestra.


Abstract Objective: To review aortic dissection (AD) in the Mexican population. Method: A retrospective study was conducted using 434 medical records of patients with aortic angio-tomography between November 2014 and October 2015. A sample was obtained of 32 patients with a first time diagnosis of AD. An analysis was performed of the dissections according to gender, age group, Stanford/De Bakey classification, and mortality rate 6 months after diagnosis. Statistical analysis was performed by obtaining the Chi squared index for the independent variables of gender, Marfan syndrome, systemic arterial hypertension, as well as calcified atheromatous disease in association with dissection subtypes, re-entry sites, and hypo-perfusion signs. Results: The patients included 65.6% males with a mean age of 54.5 years, and 34.4% females with mean age of 42.5 years. The most common dissection subtype was B/3. Mortality rate at 6 months was 18.7%. There was a significant association, with a marginal P in patients with Marfan syndrome and Stanford subtypes of AD (P = .0506). There was a significant association in patients with abdominal aortic aneurysm, when compared with Stanford subtypes of AD (P = .047104). Conclusions: AD is an emergency in which diagnosis and timely management are essential to improve prognosis. In the sample presented here, a significant association was found in patients with a history of Marfan syndrome and abdominal aneurysms with dissections according to the Stanford classification. The rest of the independent variables did not show any significant association, probably related to the size of the sample.

ABSTRACT

Summary Objective: To investigate the positive association between the presence of simple renal cysts (SRCs) and abdominal aortic aneurysm (AAA). Method: In a retrospective case-control study including subjects aged > 50 years, we evaluated the incidence of SRCs on computed tomography (CT) scan. We compared 91 consecutive patients with AAA referred from the Division of Vascular Surgery and 396 patients without AAA, randomly selected after being matched by age and gender from 3,186 consecutive patients who underwent abdominal CT. SRC was defined as a round or oval low-attenuation lesion with a thin wall and size > 4 mm on CT without obvious evidence of radiographic enhancement or septations. Patients were considered as having AAA if the size of aorta was greater than 3.0 cm. Results: Patients with AAA and without AAA were similar in terms of age (67.9± 8.41 vs. 68.5±9.13 years) (p=0.889) and gender (71.4 vs. 71.2% of male subjects, respectively) (p=0.999). There was no difference in the prevalence of SRC between case and controls. Among individuals with AAA, 38 (41.8%; [95CI 32.5-52.6]) had renal cysts compared to 148 (37.4%; [95CI 32.7-42.2]) in the control group (p=0.473), with a prevalence ratio (PR) of 1.16 (95CI 0.80-1.68). Conclusion: We found no significant differences in the prevalence of SRCs among patients with AAA and controls. Our findings suggest that the presence of SRCs is not a risk factor or a marker for AAA.


Resumo Objetivo: Avaliar uma possível associação entre presença de cistos renais simples (CRS) e aneurisma aórtico abdominal (AAA). Método: Em um estudo de caso versus controle com sujeitos com idade > 50 anos, avaliamos a prevalência de CRS detectados por tomografia computadorizada (TC). Comparamos os achados de 91 pacientes consecutivos com AAA oriundos da Divisão de Cirurgia Vascular com 396 pacientes sem AAA, randomicamente selecionados e ajustados por idade e gênero dentre 3.186 pacientes consecutivos que se submeteram a TC abdominal. Cisto simples foi definido como lesão hipodensa oval ou arredondada com paredes finas, maiores do que 4 mm em TC sem realce contrastual ou septação. Pacientes foram considerados com AAA quando o diâmetro da aorta era maior que 3,0 cm. Resultados: Pacientes com AAA e sem AAA eram semelhantes quanto a idade (67,9±8,41 vs. 68,5±9,13 anos) (p=0,889) e gênero (71,4 vs. 71,2% dos indivíduos masculinos, respectivamente) (p=0,999). Não havia diferença de prevalência de CRS entre casos e controles. Dentre indivíduos com AAA, 38 (41,8%; [IC95% 32,5-52,6]) tinham cistos renais, comparados com 148 (37,4%; [IC95% 32,7-42,2]) no grupo controle (p=0,473), com uma razão de prevalência (RP) de 1,16 (IC95% 0,80-1,68). Conclusão: Não observamos diferenças significativas na prevalência de CRS entre pacientes com AAA e controles. Nossos resultados sugerem que presença de CRS não é fator de risco ou preditor para AAA.

ABSTRACT

Abstract Advent of antiretroviral therapy has increased survival of patients with human immunodeficiency virus (HIV) infections, with the result that some of these patients now develop degenerative diseases, such as atherosclerotic aneurysms. Degenerative thoracoabdominal aortic aneurysm is rare in HIV patients. In this report, a 63-year-old male patient with HIV submitted to open repair of thoracoabdominal aortic aneurysm. The patient did not suffer any type of complication in the perioperative period and remained well in a 28-month follow-up period. In summary, open repair still remains a good alternative for aortic complex aneurysms even in HIV patients.

ABSTRACT

Abstract Objective: The endovascular repair of aortic abdominal aneurysms exposes the patients and surgical team to ionizing radiation with risk of direct tissue damage and induction of gene mutation. This study aims to describe our standard of radiation exposure in endovascular aortic aneurysm repair and the factors that influence it. Methods: Retrospective analysis of a prospective database of patients with abdominal infra-renal aortic aneurysms submitted to endovascular repair. This study evaluated the radiation doses (dose area product (DAP)), fluoroscopy durations and their relationships to the patients, aneurysms, and stent-graft characteristics. Results: This study included 127 patients with a mean age of 73 years. The mean DAP was 4.8 mGy.m2, and the fluoroscopy time was 21.8 minutes. Aortic bilateral iliac aneurysms, higher body mass index, aneurysms with diameters larger than 60 mm, necks with diameters larger than 28 mm, common iliac arteries with diameters larger than 20 mm, and neck angulations superior to 50 degrees were associated with an increased radiation dose. The number of anatomic risk factors present was associated with increased radiation exposure and fluoroscopy time, regardless of the anatomical risk factors. Conclusion: The radiation exposure during endovascular aortic aneurysm repair is significant (mean DAP 4.8 mGy.m2) with potential hazards to the surgical team and the patients. The anatomical characteristics of the aneurysm, patient characteristics, and the procedure's technical difficulty were all related to increased radiation exposure during endovascular aortic aneurysm repair procedures. Approximately 40% of radiation exposure can be explained by body mass index, neck angulation, aneurysm diameter, neck diameter, and aneurysm type.

ABSTRACT

Abstract A 78-year-old patient presented with shortness of breath after falling down. Transthoracic echocardiogram showed an extensive thrombus in the right atrium (RA), extensive thrombosis of the inferior vena cava (IVC), and abdominal aortic aneurysm (AAA). A magnetic resonance confirmed the thrombosis of the RA extending to the IVC, which was apparently fused to the abdominal aortic aneurysm (compression? erosion?). This case illustrates a severe and rare complication of a non-treated AAA. There probably was IVC erosion by the aortic aneurysm, leading to blood stasis and extensive thrombosis of the IVC and right cardiac chambers.


Resumo Uma paciente de 78 anos procurou o serviço de emergência apresentando dispneia após sofrer queda da própria altura. O ecocardiograma transtorácico mostrou um extenso trombo no átrio direito (AD), trombose extensa da veia cava inferior (VCI), e aneurisma de aorta abdominal (AAA). A ressonância magnética confirmou a trombose do AD estendendo-se até a VCI, a qual aparentemente apresentava fusão ao aneurisma da aorta abdominal (compressão? erosão?). Este caso ilustra uma complicação grave e rara de um AAA não tratado. Provavelmente houve uma erosão da VCI pelo aneurisma da aorta resultando em estase sanguínea e trombose extensa da veia cava inferior e cavidades cardíacas direitas.

ABSTRACT

ABSTRACT A 59 year-old patient was admitted with upper gastrointestinal bleeding. The clinical exam showed mild hypotension and blood samples revealed acute anemia (hemoglobin = 7.5 g/dl). Emergency computed tomography showed an infrarenal abdominal aortic aneurysm and extravasation of the arterial contrast material toward the digestive tract. The patient was transported to the operating room for emergency laparotomy, which showed an aortoduodenal fistula. After proximal and distal aortic vascular control, the two anatomical structures were dissected with duodenorrhaphy, patch repair of the aortic tear and omentum interposition. The postoperative recovery was uneventful, with discharge after 12 days.

ABSTRACT

OBJECTIVE: The purpose of this study was to evaluate the effectiveness of detachable interlock microcoils for an embolization of the internal iliac artery during an endovascular aneurysm repair (EVAR). MATERIALS AND METHODS: A retrospective review was conducted on 40 patients with aortic aneurysms, who had undergone an EVAR between January 2010 and March 2012. Among them, 16 patients were referred for embolization of the internal iliac artery for the prevention of type II endoleaks. Among 16 patients, 13 patients underwent embolization using detachable interlock microcoils during an EVAR. Computed tomographic angiographies and clinical examinations were performed during the follow-up period. Technical success, clinical outcome, and complications were reviewed. RESULTS: Internal iliac artery embolizations using detachable interlock microcoils were technically successful in all 13 patients, with no occurrence of procedure-related complications. Follow-up imaging was accomplished in the 13 cases. In all cases, type II endoleak was not observed with computed tomographic angiography during the median follow-up of 3 months (range, 1-27 months) and the median clinical follow-up of 12 months (range, 1-27 months). Two of 13 (15%) patients had symptoms of buttock pain, and one patient died due to underlying stomach cancer. No significant clinical symptoms such as bowel ischemia were observed. CONCLUSION: Internal iliac artery embolization during an EVAR using detachable interlock microcoils to prevent type II endoleaks appears safe and effective, although this should be further proven in a larger population.

ABSTRACT

Extracranial internal carotid artery aneurysms are rare. They may result in thromboembolic phenomena but spontaneous rupture is rare. The clinical presentation may be an asymptomatic neck mass or there may be symptoms of upper aerodigestive tract compression. The diagnosis may be suspected on clinical examination but radiologic investigations play an important role in diagnosis as well as in assessing the risk of complications of surgical intervention. We present a case of a patient with an extracranial internal carotid artery aneurysm, along with a short review of the treatment options.


Los aneurismas de la arteria carótida interna extracraneal son raros. Pueden ocasionar fenómenos tromboembólicos pero la ruptura espontánea no es común. La manifestación clínica puede ser una masa asintomático en el cuello, o pueden presentarse síntomas de compresión de las vías aerodigestivas superiores. Pueden producirse indicios para el diagnóstico a partir de sospechas durante el examen clínico, pero las investigaciones radiológicas desempeñan un papel importante a la hora de diagnosticar, y evaluar el riesgo de complicaciones de la intervención quirúrgica. Presentamos un caso de un paciente con un aneurisma de la arteria carótida interna extracraneal, junto con una breve reseña de las opciones de tratamiento.

ABSTRACT

Fenestrated endovascular repair of an abdominal aortic aneurysm has been developed to treat patients with a short or complicated aneurysm neck. Fenestration involves creating an opening in the graft fabric to accommodate the orifice of the vessel that is targeted for preservation. Fixation of the fenestration to the renal arteries and the other visceral arteries can be done by implanting bare or covered stents across the graft-artery ostia interfaces so that a portion of the stent protrudes into the aortic lumen. Accurate alignment of the targeted vessels in a longitudinal aspect is hard to achieve during stent deployment because rotation of the stent graft may take place during delivery from the sheath. Understanding the 3D relationship of the aortic branches and the fenestrated vessel stents following fenestration will aid endovascular specialists to evaluate how the stent graft is situated within the aorta after placement of fenestrations. The aim of this article is to provide the 2D and 3D imaging appearances of the fenestrated endovascular grafts that were implanted in a group of patients with abdominal aortic aneurysms, based on the multislice CT angiography. The potential applications of each visualization technique were explored and compared with the 2D axial images.
