ABSTRACT

Introducción. El aneurisma aórtico abdominal roto, tiene una mortalidad del 80 % al 90 %. Para su reparación existe una técnica abierta y otra endovascular, las cuales tienen diferencias entre sus beneficios y complicaciones. El método de elección en la actualidad para la corrección de esta alteración anatómica es endovascular, sin embargo, no es el más usado, porque no se cuenta todo el tiempo con el equipo humano de cirugía vascular para su realización. Caso clínico. Ingresa a urgencias un paciente en estado de shock de origen desconocido, con dolor abdominal de 24 horas de evolución. Se realiza una tomografía con contraste que demuestra un aneurisma aórtico abdominal infrarrenal roto. Debido a que no se contaba con el equipo de cirugía vascular, es llevado de urgencia a una corrección abierta que duró 153 minutos, con un sangrado intraoperatorio de 1754 cc. Fue dado de alta a los 12 días postoperatorios sin ninguna complicación. Discusión. La reparación endovascular del aneurisma aórtico abdominal roto es la mejor elección, ya que muestra mayores beneficios en comparación con la reparación abierta, sin embargo, no es el más utilizado, porque se necesita de un personal bien entrenado en cirugía endovascular, por lo que, dentro de la formación de los cirujanos generales, se tiene que incluir el aprendizaje de las técnicas abiertas


Introduction. The ruptured abdominal aortic aneurysm has a mortality of 80% to 90%. There is an open and an endovascular techniques for its repair, which have differences between their benefits and complications. The method of choice for the correction of this anatomical alteration is endovascular; however, it is not the most frequently used, mainly because the vascular surgical team is not available all the time to perform it.Clinical case. A patient in a state of shock of unknown origin was admitted to the emergency room, with abdominal pain of 24 hours of evolution. A contrast-enhanced CT scan demonstrated a ruptured infrarenal abdominal aortic aneurysm. Due to the lack of a vascular surgery team, the patient was rushed for an open surgery that lasted 153 minutes, with an intraoperative bleeding of 1754 cc. He was discharged 12 days after surgery without any complications.Discussion. Endovascular repair of ruptured abdominal aortic aneurysm is the best choice, since it shows greater benefits compared to open repair. However, it is not the most widely used because it requires well-trained personnel in endovascular surgery. Therefore, learning of open techniques must be included in the training of general surgeons

ABSTRACT

Abstract Although aortic valve replacement remains the gold standard treatment for aortic valve diseases like stenosis (AS) or insufficiency, new surgical methods have been developed with a focus in the reconstruction of the aortic valve rather than replacing it. The Ozaki procedure involves a tailored replacement of each individual valvular leaflet with glutaraldehyde-treated autologous pericardium and aims to reproduce the normal anatomy of the aortic valve. Cases of patients with unicuspid aortic valve treated with the Ozaki procedure are uncommon in the litrature and become even more rare when it comes to concomitant diseases like AS and ascending aorta aneurysm. We present the case of a 21-year-old, fit and asymptomatic male, with unicuspid aortic valve with severe stenosis and ascending aorta dilatation, surgically treated with tricuspidization of the aortic valve with glutaraldehyde-treated autologous pericardium and replacement of the ascending aorta with a straight synthetic graft. Postoperative studies showed a fully functional, neo-tailored tricuspid aortic valve with trivial regurgitation. The patient had an uncomplicated recovery, stayed in the intensive care unit for 2 days and was discharged on the 7th postoperative day.

ABSTRACT

OBJECTIVES: We sought to analyze the hemodynamic effects of the multilayer flow-modulated stent (MFMS) in Thoracoabdominal aortic aneurysms (TAAAs). METHODS: The hemodynamic effects of MFMS were analyzed in aortic thoracoabdominal aneurysms in experimental swine models. We randomly assigned 18 pigs to the stent or control groups and underwent the creation of an artificial bovine pericardium transrenal aneurysm. In the stent group, an MFMS (Cardiatis, Isnes, Belgium) was immediately implanted. After 4 weeks, we evaluated aneurysm sac thrombosis and renal branch patency by angiography, duplex scan, and morphological analysis. RESULTS: All the renal arteries remained patent after re-evaluation in both groups. Aneurysmal sac thrombosis was absent in the control group, whereas in the stent group it was present in 66.7% of aneurysmal sacs (p=0.061). The mean final aneurysm sac diameter was significantly lower in the stent group (mean estimated reduction, 6.90 mm; p=0.021). The proximal neck diameter decreased significantly in the stent group (mean difference, 2.51 mm; p=0.022) and grew significantly in the control group (mean difference, 3.02 mm; p=0.007). The distal neck diameter increased significantly in the control group (mean difference, 3.24 mm; p=0.017). There were no significant findings regarding distal neck measurements in the stent group. CONCLUSION: The MFMSs remained patent and did not obstruct the renal arteries within 4 weeks. In the stent group, the device was also associated with a significant decrease in aneurysmal sac diameter and a large proportion (albeit non-significant) of aneurysmal sac thrombosis.

ABSTRACT

Abstract Objective: To give an overview of the Ortner's syndrome caused by an aortic arch aneurysm. Methods: By comprehensive retrieval of the pertinent literature published in the past two decades, 75 reports including 86 patients were collected and recruited into this study along with a recent case of our own. Results: The aortic arch aneurysms causing hoarseness were most commonly mycotic aneurysms. In this patient setting, in addition to the left recurrent laryngeal nerve, trachea was the most commonly affected structure by the aortic arch aneurysm. Surgical/interventional/hybrid treatments led to a hoarseness-relieving rate of 64.3%, much higher than that of patients receiving conservative treatment. However, hoarseness recovery took longer time in the surgically treated patients than in the interventionally treated patients. Conclusion: The surgical and interventional treatments offered similar hoarseness-relieving effects. Surgical or interventional treatment is warranted in such patients for both treatment of arch aneurysms and relief of hoarseness.

ABSTRACT

Abstract Giant ascending aortic aneurysm is a rare condition. In this paper, we present an uncommon case of giant ascending aortic aneurysm with a maximal diameter of 14 cm in a 77-year-old woman presenting with unusual symptoms. The patient underwent a successful surgery involving ascending aortic replacement, and was discharged without any complication. After discharge, she was followed regularly and no major problem was observed in her control visits. To the best of our knowledge, our case is the largest ascending aortic aneurysm reported to date in the existing literature.

ABSTRACT

Abstract Left sinus of Valsalva aneurysm (SVA) is a very infrequent clinical entity. Valsalva aneurysms are often asymptomatic in right and non-coronary sinuses and the diagnosis is often incidental. A left SVA which presents with exertional chest pain due to compression of left coronary system arteries is extremely rare. In this case, we present a successful surgical repair of left SVA without aortic regurgitation or myocardial infarction in a 59-year-old male patient.

ABSTRACT

Abstract Aneurysms of the sinuses of Valsalva are defined as dilatation of the aortic root region between the aortic annulus and the sinotubular junction. Isolated aneurysms of the sinus of Valsalva are rare cardiovascular pathologies. They may be congenital, especially secondary to connective tissue disorders or in conjunction with congenital cardiac defects, or acquired such as secondary to infections or trauma. Small sized aneurysm without rupture in asymptomatic patients may be followed; however, latter cases require intervention and surgery is the gold standard treatment modality. In this report, a 41-year-old male patient was reported with giant aneurysm of the non-coronary sinus of Valsalva whom underwent aortic root sparing surgical aortic sinus of Valsalva reconstruction.

ABSTRACT

Los aneurismas aórticos corresponden a una dilatación focal de la pared de la arteria que supera el 50% de su diámetro normal. La mayoría de los casos corresponden a la localización abdominal, siendo una pequeña proporción descritos a nivel de la aorta torácica. En este segmento, menos del 10% de los pacientes experimentan síntomas e incluso, la ruptura puede constituir la primera manifestación. Se presenta el caso de una mujer octogenaria con hemoptisis e inestabilidad hemodinámica en la que se realizó el diagnóstico de aneurisma de aorta torácica a través angiotomografía contrastada para luego recibir manejo endovascular de manera exitosa. Dado el pronóstico de esta patología, es vital un adecuado uso de los estudios de imagen para un acertado diagnóstico radiológico que permita un enfoque terapéutico oportuno. (AU)


Aortic aneurysms correspond to a focal dilation of the artery wall that exceeds 50% of its normal diameter. Most cases correspond to the abdominal location, being a small proportion described at the level of the thoracic aorta. In this segment, less than 10% of patients experience symptoms and even rupture may constitute the first manifestation. It is presented an octogenarian woman with hemoptysis and hemodynamic instability in which the diagnosis of thoracic aortic aneurysm was made through contrasting angiotomography and then she receives a successfully endovascular management. Given the prognosis of this pathology, an adequate use of imaging studies is vital for a successful radiological diagnosis that allows for a timely therapeutic approach. (AU)

ABSTRACT

Abstract An 89-year-old female patient presented to our cardiology outpatient clinic complaining of shortness of breath and back pain. Chest X-ray demonstrated a widened mediastinum. Transthoracic echocardiography showed an ascending aortic aneurysm and the modified apical 5-chamber view showed that left atrium was compressed between the ascending and descending aortas. Color Doppler turbulence was also seen in the compressed area. A contrast-enhanced chest computed tomography scan in axial and coronal planes showed that left atrium and pulmonary veins were compressed by ascending and descending aortic aneurysms. Herein, we illustrated this rare condition diagnosed by transthoracic echocardiography in combination with computed tomography.

ABSTRACT

ABSTRACT: Bicuspid aortic valve (BAV) disease is generally associated with thoracic aortic dilatation (TAD). Related factors include; genetical, morphological (valvular phenotype) and most recently, hemodynamic profiles associated with flow pattern and wall shear stress. Cardiac magnetic resonance 4D Flow (4DF) can give an integral evaluation of these later flow variables. Remarkable, different spectrums of flow and vortex direction exist in BAV that are related to the site of TAD (proximal or distal). Therefore, we present a 57 years old patient with BAV (Sievers 0) with anteroposterior leaflets distribution in which 4DF depicted an anteriorly and righthand oriented jet that correlated with the zone of grater AD; also, vortex rotation was counterclockwise, corresponding to the most frequent vortex type in BAV. In conclusion, 4DF is a powerful and ground-breaking tool that enhances our knowledge of BAV related aortopathy.

ABSTRACT

Abstract Objective: Treatment of acute diseases of the aorta is still associated with high mortality and morbidity. It is believed that interventions for these diseases on overtime hours (night shifts or weekend shifts) may increase mortality. In this study, we investigated the effect of performing acute type A aortic dissection surgery on overtime hours in terms of postoperative outcomes. Methods: 206 patients who underwent emergency surgery for acute type A aortic dissection were retrospectively evaluated. Two groups were constituted: patients operated on daytime working hours (n=61), and patients operated on overtime hours (n=145), respectively. Results: Chronic obstructive pulmonary disease and repeat surgery were higher in group 1. There was no statistically significant difference between the two groups in terms of operative and postoperative results. Mortality rates and postoperative neurological complications in group 1 were 9.8% and 13.1%, respectively. In group 2, these rates were 13.8% and 12.4%, respectively (P=0.485 - P=0.890). Multivariate analysis identified that cross-clamp time, amount of postoperative drainage, preoperative loss of consciousness and postoperative neurological complications are the independent predictors of mortality. Conclusions: As the surgical experience of the clinics improves, treatment of acute type A aortic dissections can be successfully performed both overtime and daytime working hours.

ABSTRACT

Abstract A 27-year-old woman with sudden back pain was transported to our hospital. Abdominal ultrasonography revealed pregnancy of 28 weeks' gestation. Computed tomography demonstrated a type A aortic dissection. Because of progressive fetal deterioration, an emergency cesarean section was forced to perform. The next day, simple hysterectomy followed by an aortic procedure was completed. Valve-sparing aortic replacement and total arch replacement were employed as central operations. The mother and baby are well 9 months postoperatively. Although the strategy for acute type A aortic dissection during pregnancy is controversial, collaborations among neonatologists, obstetricians, and cardiovascular surgeons can ensure mother and infant survival.

ABSTRACT

Abstract Aortic dissection (AD) has been recognized to be associated with an inflammatory process. Clinical observations demonstrated that patients with AD had an elevated interleukin (IL)-6 level in comparison to hypertensive or healthy controls. Adverse events such as acute lung injury, postimplantation syndrome, and death are associated with an elevated IL-6 level. Thus, circulating IL-6 could be a reliable biomarker for the diagnosis of AD and for the eveluation of the therapeutic outcomes and the prognosis of AD patients. Therapeutic interventions aiming at attenuating the inflammatory status by IL-6 neutralization could effectively decrease the IL-6 level and thus reverse the progression of the disorder of AD patient. Endovascular aortic repair can effectively control the inflammatory cytokines. Selective antegrade cerebral perfusion with deep hypothermic circulatory arrest during aortic arch replacement shows better neuroprotectve effect with an improved IL-6 level of the cerebrospinal fluid. These results facilitate the understanding of the etiology of AD and guide the directions for the treatment of acute AD in the future. More effective therapeutic agents developed based on the theories of IL-6 signaling involved in the mechasims of AD are anticipated.

ABSTRACT

Resumen Introducción: el aneurisma de aorta tiene una prevalencia de 5,7%; sin tratamiento su desenlace final es la ruptura y en ocasiones la muerte. En la actualidad, existe el reparo endovascular mediante prótesis fenestradas para pacientes en quienes es inviable el procedimiento quirúrgico. Están diseñadas para adaptarse a la anatomía única de cada paciente y dan cabida al flujo de uno o más vasos viscerales logrando resultados satisfactorios. Objetivo: reportar una serie de casos de pacientes con aneurismas de aorta tratados mediante endoprótesis fenestradas en un centro de referencia cardiovascular de Medellín, Colombia, entre 2013 y 2017. Método: estudio descriptivo, restrospectivo, de una serie de casos, cuya información se obtuvo por medio de una fuente secundaria. Resultados: los resultados se presentaron como porcentajes y frecuencias. Se utilizó el programa SPSS versión 20.0. La mayoría de los pacientes fueron hombres, con promedio de edad de 69,5 ±7,9 años. La mediana del diámetro aneurismático fue de 6,0 cm (RIQ 5,0-8,25). La mayoría de las complicaciones fueron vasculares. El 80,0% de los pacientes tuvieron algún seguimiento radiológico al mes, 6 meses o a los 12 meses después de la intervención; el 100,0% requirió revascularización del o los vasos intervenidos. Conclusiones: se considera que el balance adecuado entre riesgos y beneficios que otorga la técnica hace que, para el grupo específico de pacientes cuyas características clínicas y anatómicas hacen poco factible la cirugía, el uso de las prótesis fenestradas sea seguro y tenga resultados clínicos y de supervivencia similares al compararse con la literatura.


Abstract Introduction: Aortic aneurysm has a prevalence of 5.7%. Its final outcome without is a rupture, and occasionally death. Endovascular repair can currently be carried out using a fenestrated stent graft in patients in whom a surgical procedure is not feasible. These grafts are designed to adapt to the unique anatomy of each patient, and makes room for one or more visceral vessels to flow, achieving satisfactory results. Objective: To report a case series of patients with aortic aneurysms treated with a fenestrated stent graft between 2013 and 2017 in a cardiovascular reference centre in Medellín, Colombia. Method: A descriptive, retrospective study was conducted on a case series, in which the information was obtained for a secondary source. The results are presented as percentages and frequencies. The statistics program SPSS version 20.00 was used. Results: The majority of patients were male, and the mean age was 69.5 ±7.9 years. The median aneurysm diameter was 6.0 cm (IQR 5.0-8.25). The majority of complications were vascular. Some type of radiological follow-up was carried out on 80% of the patients at one month, 6 months, and 12 months after the intervention. All of them (100%) required revascularisation of the vessels intervened. Conclusions: The risk-benefit ratio is considered adequate for this technique. It means that, for the specific group of patients that have clinical and anatomical characteristics that make surgery highly unlikely, the use of fenestrated stent grafts are safe, and have similar clinical and survival results when compared with the literature.
