ABSTRACT

Aortoiliac occlusive disease (AIOD) refers to the stenosis and occlusion of the distal abdominal aorta and(or) bifurcation of the aortoiliac artery,which is mainly caused by atherosclerosis,leading to pelvic and lower limb ischemia.Open surgery has always been the main treatment for complex AIOD.However,in recent years,with the development of endovascular surgery technologies and medical instruments,its treatment concept has been greatly changed.More and more clinical evidence has proved that the long-term efficacy of endovascular therapy is not inferior to that of traditional open surgery,so minimally invasive endovascular therapy has become the preferred treatment for AIOD.

ABSTRACT

Abstract We report the case of a 41-year-old female who presented with left upper limb embolization due to primary thoracic aortic mural thrombus; this latter represented an uncommon condition with difficult diagnosis and a high rate of life-threatening complications. Upper extremities embolization is extremely rare because it usually occurs in the lower limbs. Management strategy is still controversial, and no clear guidelines indicate superiority of either conservative or invasive treatment approach to date. Our report illustrates how endovascular exclusion of thoracic aortic mural thrombus has the advantage to be a low-risk procedure that represents a definitive therapy.

ABSTRACT

Abstract Objective: To review the currently available literature to define the role of thoracic endovascular aortic repair (TEVAR) in patients with connective tissue disorders (CTD). Methods: A comprehensive electronic database search was performed in PubMed, SCOPUS, Embase, Google scholar, and OVID to identify all the articles that reported on outcomes of utilizing TEVAR in patients with CTD during elective and emergency settings. The search was not limited to time or language of the published study. Results: All the relevant studies have been summarized in its correspondence section. The outcomes were analyzed in narrative format. The role of TEVAR has been elaborated as per each study. Currently, there is limited large cohort size studies outlining the use of TEVAR in patients with CTD. The use of endovascular repair in patients with CTD is limited due to progressive aortic dilatations and high possibility of further reinterventions at later stage of life. Conclusion: Open repair remains the gold standard method of intervention in young patients with progressive CTD, especially in the setting of acute type A aortic dissection. However, TEVAR can be sought as a reliable alternative in emergency setting of diseases involving the descending thoracic aorta; yet the long-term data needs to be published to support such practice.

ABSTRACT

Abstract Regardless the successful treatment of the descending aorta with endovascular prosthesis, for the ascending aorta segment, because of several anatomic and physiologic issues, this technique has been considered an alternative only for high-risk or inoperable patients. Despite restricted indications, hundreds of treatments have been performed worldwide, demonstrating its safety and reproducibility if it is done in high-quality centers. Therefore, understanding patients' selection criteria and technique limitations are critical to its application.

ABSTRACT

Abstract Ventricular assist devices (VADs) are an important technological development for patients with end-stage heart failure, and approximately 50% of these patients require various additional cardiac procedures. Here we presente the case of a patient suffering from severe aortic insufficiency, aortic root dilatation, and an ascending aortic aneurysm with end-stage decompensated heart failure. We performed the Bentall procedure combined with a left VAD implantation during the same session. The postoperative period was uneventful for this patient, and he was discharged on the 32nd postoperative day. The heart failure symptoms of the patient are reasonable, and he is still on the heart transplantation waiting list.

ABSTRACT

Resumen Introducción: En México no se cuentan con estadísticas adecuadas acerca de la enfermedad aórtica, que puede ser tratada mediante manejo médico o cirugía abierta o endovascular. Objetivo: Identificar la literatura en bases de datos electrónicas relativa al manejo invasivo de la patología aórtica en México. Método: Se realizó búsqueda sistemática y revisión narrativa de la literatura disponible en diferentes bases de datos electrónicas: PubMed, Imbiomed, Clinical Key, Bibliat, Scielo, Sage Journals, Sciencedirect y con el motor de búsqueda de Google Académico. Resultados: Se encontraron 90 artículos, de los cuales 50 reunían los criterios de inclusión. Fueron seleccionados estudios observacionales y reportes de casos, con énfasis en los datos demográficos de los pacientes, resultados clínicos y la supervivencia posoperatoria a 30 días. Conclusión: Se reporta elevada tasa de complicaciones de las enfermedades aórticas debido al infradiagnóstico de estas, que deriva en manejo más complejo y pronóstico desfavorable. La creación de un registro nacional de patología aórtica es crucial para la estandarización en el abordaje y la optimación de los resultados.


Abstract Introduction: In Mexico, there are no appropriate statistical data on aortic disease, which can be treated with medical management or open or endovascular surgical approach. Objective: To carry out a systematic search and review of the literature in electronic databases with regard to invasive management of aortic pathology in Mexico. Method: A systematic search and narrative review of available literature was carried out using different electronic databases: PubMed, Imbiomed, Clinical Key, Bibliat, Scielo, Sage Journals and Sciencedirect, as well as with the Google Scholar search engine. Results: Ninety articles were found, out of which only 53 met the inclusion criteria. Observational studies and case reports were selected, emphasizing on patient demographics, clinical results, and 30-day postoperative survival. Conclusion: An elevated rate of complications is reported for aortic pathologies due to underdiagnosis, which results in management being more complicated and prognosis unfavorable. The creation of a national aortic disease registry is crucial to standardization in the approach and optimization of results.

ABSTRACT

Abstract Introduction: Three-dimensional (3D) printing has become an affordable tool for assisting heart surgeons in the aorta endovascular field, both in surgical planning, education and training of residents and students. This technique permits the construction of physical prototypes from conventional medical images by converting the anatomical information into computer aided design (CAD) files. Objective: To present the 3D printing feature on developing prototypes leading to improved aortic endovascular surgical planning, as well as transcatheter aortic valve implantation, and mainly enabling training of the surgical procedure to be performed on patient's specific condition. Methods: Six 3D printed real scale prototypes were built representing different aortic diseases, taken from real patients, to simulate the correction of the disease with endoprosthesis deployment. Results: In the hybrid room, the 3D prototypes were examined under fluoroscopy, making it possible to obtain images that clearly delimited the walls of the aorta and its details. The endovascular simulation was then able to be performed, by correctly positioning the endoprosthesis, followed by its deployment. Conclusion: The 3D printing allowed the construction of aortic diseases realistic prototypes, offering a 3D view from the two-dimensional image of computed tomography (CT) angiography, allowing better surgical planning and surgeon training in the specific case beforehand.

ABSTRACT

Abstract Pulmonary interstitial emphysema (PIE) is a common problem in premature neonates with respiratory distress syndrome. This condition is often related to barotrauma caused by mechanical ventilation or continuous positive airway pressure applied to low birth weight neonates. The clinical diagnosis can be challenging. However, after proper diagnosis, several interventions are available for successful management. We describe an infant who developed severe PIE with recurrent pneumothoraces and development of a persistent bronchopleural fistula shortly after repair of a hypoplastic aortic arch and description of successful lobectomy with the assistance of extracorporeal support (ECMO).

ABSTRACT

Penetrating aortic ulcer (PAU) is an ulceration of an atherosclerotic plaque which disrupts the aortic internal elastic lamina and that can evolve to an intramural hematoma (IH), aortic dissection or aortic rupture. We report two cases with PAU. A 73 year-old woman with a history of hypertension, presented with acute chest pain of three days of evolution and a hypertensive emergency. An electrocardiogram showed ST-segment elevation and elevated cardiac enzymes. Computed tomography (CT) scans showed an acute ascending aortic mural hematoma secondary to PAU and hemopericardium. Replacement of ascending aorta was performed with a vascular prosthesis with extracorporeal circulation (ECC). PAU and IH were confirmed by histopathology. A 62-year old woman with a history of hypertension, diabetes and chronic obstructive pulmonary disease, consulted for abdominal pain of two days of evolution. A thoracic-abdominal CT scan visualized an uncomplicated PAU and an abdominal aortic aneurysm. Because of abdominal pain and signs of peritoneal irritation, an exploratory laparotomy was performed finding a typhlitis. Resection and ileo-ascendo-anastomosis were performed. A new CT scan showed PAU with high risk of rupture without a clinical acute aortic syndrome. The patient was operated replacing the ascending aorta with a vascular prosthesis using ECC. Three PAU were found. Histopathology confirmed the diagnosis. Both patients evolved without postoperative complications.

ABSTRACT

Abstract Introduction: Oxidative stress seems to be a role in the atherosclerosis process, but research in human beings is scarce. Objective: To evaluate the role of oxidative stress on human aortas of patients submitted to surgical treatment for advanced aortoiliac occlusive disease. Methods: Twenty-six patients were divided into three groups: control group (n=10) formed by cadaveric organ donors; severe aortoiliac stenosis group (patients with severe aortoiliac stenosis; n=9); and total aortoiliac occlusion group (patients with chronic total aortoiliac occlusion; n=7). We evaluated the reactive oxygen species concentration, nicotinamide adenine dinucleotide phosphate-oxidase, superoxide dismutase and catalase activities as well as nitrite levels in samples of aortas harvested during aortofemoral bypass for treatment of advanced aortoiliac occlusive disease. Results: We observed a higher level of reactive oxygen species in total aortoiliac occlusion group (48.3±9.56 pmol/mg protein) when compared to severe aortoiliac stenosis (33.5±7.4 pmol/mg protein) and control (4.91±0.8 pmol/mg protein) groups (P<0.05). Nicotinamide adenine dinucleotide phosphate oxidase activity was also higher in total aortoiliac occlusion group when compared to the control group (3.81±1.7 versus 1.05±0.31 µmol/min.mg protein; P<0.05). Furthermore, superoxide dismutase and catalase activities were significantly higher in the severe aortoiliac stenosis and total aortoiliac occlusion groups when compared to the control cases (P<0.05). Nitrite concentration was smaller in the severe aortoiliac stenosis group in comparing to the other groups. Conclusion: Our results indicated an increase of reactive oxygen species levels and nicotinamide adenine dinucleotide phosphate-oxidase activity in human aortic samples of patients with advanced aortoiliac occlusive disease. The increase of antioxidant enzymes activities may be due to a compensative phenomenon to reactive oxygen species production mediated by nicotinamide adenine dinucleotide phosphate oxidase. This preliminary study offers us a more comprehensive knowledge about the role of oxidative stress in advanced aortoiliac occlusive disease in human beings.

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

AbstractObjective:To compare the results of the root reconstruction with the aortic valve-sparing operation versus composite graftvalve replacement.Methods:From January 2002 to October 2013, 324 patients underwent aortic root reconstruction. They were 263 composite graft-valve replacement and 61 aortic valve-sparing operation (43 reimplantation and 18 remodeling). Twenty-six percent of the patients were NYHA functional class III and IV; 9.6% had Marfan syndrome, and 12% had bicuspid aortic valve. There was a predominance of aneurysms over dissections (81% vs. 19%), with 7% being acute dissections. The complete follow-up of 100% of the patients was performed with median follow-up time of 902 days for patients undergoing composite graft-valve replacement and 1492 for those undergoing aortic valve-sparing operation.Results:In-hospital mortality was 6.7% and 4.9%, respectively for composite graft-valve replacement and aortic valve-sparing operation (ns). During the late follow-up period, there was 0% moderate and 15.4% severe aortic regurgitation, and NYHA functional class I and II were 89.4% and 94%, respectively for composite graft-valve replacement and aortic valve-sparing operation (ns). Root reconstruction with aortic valve-sparing operation showed lower late mortality (P=0.001) and lower bleeding complications (P=0.006). There was no difference for thromboembolism, endocarditis, and need of reoperation.Conclusion:The aortic root reconstruction with preservation of the valve should be the operation being performed for presenting lower late mortality and survival free of bleeding events.


ResumoObjetivo:Analisar comparativamente os resultados da operação de preservação da valva aórtica e do tubo valvulado nas reconstruções da raiz da aorta.Métodos:No período de janeiro de 2002 a outubro de 2013, 324 pacientes foram submetidos à reconstrução da raiz da aorta. Foram 263 tubos valvulados e 61 preservações da valva aórtica (43 reimplantes e 18 remodelamentos). 26% dos pacientes estavam em classe funcional III e IV; 9,6% com síndrome de Marfan e 12% apresentavam valva aórtica bivalvulada. Houve predomínio dos aneurismas sobre as dissecções (81% contra 19%), sendo 7% de dissecções agudas. O seguimento completo de 100% dos pacientes foi realizado com tempo mediano de seguimento de 902 dias para pacientes submetidos à tubo valvulado e de 1492 para aqueles submetidos à preservação da valva aórtica.Resultados:A mortalidade hospitalar foi de 6,7% contra 4,9% respectivamente para tubo valvulado e preservação da valva aórtica (ns). No seguimento tardio, a insuficiência aórtica importante foi de 0% e 5,8%, e a insuficiência cardíaca crônica, classe funcional I e II de 89,4% e 94%, respectivamente, para tubo valvulado e preservação da valva aórtica (ns). A reconstrução da raiz da aorta com a preservação da valva aórtica apresentou menor mortalidade tardia (P=0,001) e menos complicações hemorrágicas (P=0,006). Não houve diferença para tromboembolismo, endocardite ou necessidade de reoperação.Conclusão:A reconstrução da raiz da aorta com a preservação valvar deve ser a operação a ser realizada por apresentar menor mortalidade e sobrevida livre de eventos hemorrágicos.

ABSTRACT

Objective: To compare in-hospital outcomes in aortic surgery in our cardiac surgery unit, before and after foundation of our Center for Aortic Surgery (CTA). Methods: Prospective cohort with non-concurrent control. Foundation of CTA required specialized training of surgical, anesthetic and intensive care unit teams, routine neurological monitoring, endovascular and hybrid facilities, training of the support personnel, improvement of the registry and adoption of specific protocols. We included 332 patients operated on between: January/2003 to December/2007 (before-CTA, n=157, 47.3%); and January/2008 to December/2010 (CTA, n=175, 52.7%). Baseline clinical and demographic data, operative variables, complications and in-hospital mortality were compared between both groups. Results: Mean age was 58±14 years, with 65% male. Group CTA was older, had higher rate of diabetes, lower rates of COPD and HF, more non-urgent surgeries, endovascular procedures, and aneurysms. In the univariate analysis, CTA had lower mortality (9.7 vs. 23.0%, P=0.008), which occurred consistently across different diseases and procedures. Other outcomes which were reduced in CTA included lower rates of reinterventions (5.7 vs 11%, P=0.046), major complications (20.6 vs. 33.1%, P=0.007), stroke (4.6 vs. 10.9%, P=0.045) and sepsis (1.7 vs. 9.6%, P=0.001), as compared to before-CTA. Multivariable analysis adjusted for potential counfounders revealed that CTA was independently associated with mortality reduction (OR=0.23, IC 95% 0.08 – 0.67, P=0.007). CTA independent mortality reduction was consistent in the multivariable analysis stratified by disease (aneurysm, OR=0.18, CI 95% 0.03 – 0.98, P=0.048; dissection, OR=0.31, CI 95% 0.09 – 0.99, P=0.049) and by procedure (hybrid, OR=0.07, CI 95% 0.007 – 0.72, P=0.026; Bentall, OR=0.18, CI 95% 0.038 – 0.904, P=0.037). Additional multivariable predictors of in-hospital mortality included creatinine ...


Objetivo: Comparar desfechos intrahospitalares em pacientes submetidos a cirurgia da aorta torácica e toracoabdominal, antes e após a constituição do Centro Especializado de Tratamento da Aorta (CTA). Métodos: Coorte prospectiva com controle não contemporâneo. A criação do CTA envolveu treinamento cirúrgico especializado, sala híbrida, monitorização neurológica, capacitação de pessoal de apoio, aperfeiçoamento dos registros e uso de protocolos específicos. Foram incluídos 332 pacientes operados em 2 períodos: janeiro/2003 a dezembro/2007 (pré-CTA, n=157, 47,3%); e janeiro/2008 a dezembro/2010 (CTA, n=175, 52,7%). As características demográficas, clínicas, dados cirúrgicos, complicações e mortalidade hospitalar foram comparados nos 2 grupos. Resultados: A idade média foi 58±14 anos, com 65% sexo masculino. O grupo CTA teve idade, prevalência de diabete (DM) e glicemia maiores; menor prevalência de doença pulmonar obstrutiva crônica e insuficiência cardíaca; maior proporção de aneurismas e cirurgias eletivas; e mais procedimentos endovasculares que o pré-CTA. Na análise univariada, o grupo CTA mostrou redução de mortalidade (9,7% x 23,0%, P=0,008), que foi consistente nos diferentes subgrupos estratificados por patologia e por procedimento. O grupo CTA teve também redução de reoperações (5,7% x 11%, P=0,046), complicações maiores (20,6% x 33,1%, P=0,007), acidente vascular cerebral (4,6% x 10,9%, P=0,045) e sepse (1,7% x 9,6%, P=0,001), comparado ao pré-CTA. Na análise multivariada, o CTA se associou de forma independente a redução de mortalidade hospitalar (OR=0,23, IC 95% 0,08 - 0,67, P=0,007). A redução de mortalidade do CTA também ocorreu na análise estratificada por patologia (cirurgias de aneurisma, OR=0,18, IC 95% 0,03 - 0,98, P=0,048; cirurgias de dissecção, OR=0,31, IC 95% 0,09 - 0,99, P=0,049) e por procedimento (híbridos, OR=0,07, IC 95% 0,007 - 0,72, P=0,026; Bentall, OR=0,18, IC 95% 0,038 – 0,904, P=0,037).

ABSTRACT

Introdução: O manejo das doenças da aorta torácica que envolvem a aorta ascendente, arco aórtico e aorta torácica descendente constituem um desafio técnico e é uma área em constante desenvolvimento e inovação. Objetivo: Analisar os resultados iniciais e a médio prazo do tratamento híbrido das doenças do arco aórtico. Métodos: Estudo retrospectivo de procedimentos realizados no período de janeiro de 2010 a dezembro de 2012, em que foram analisados o sucesso técnico e terapêutico, a morbimortalidade, os desfechos neurológicos, a taxa de vazamentos e de reintervenções. Resultados: Em um total de 95 pacientes tratados por doenças da aorta torácica no período, 18 realizaram o tratamento híbrido e adentraram neste estudo. A idade média foi de 62,3 anos. O sexo masculino esteve presente em 66,7%. O sucesso técnico e terapêutico foi de 94,5% obe 83,3%, respectivamente. A mortalidade perioperatória foi de 11,1%. Não houve óbito durante o acompanhamento de 1 ano. A taxa de reintervenção foi de 16,6%, devido a 2 casos de endoleak tipo Ia e um caso de endoleak tipo 2. Não foi observada oclusão dos enxertos anatômicos ou extra-anatômicos durante o período de seguimento. Conclusão: O tratamento híbrido das doenças do arco aórtico demonstrou ser uma alternativa viável à cirurgia convencional. As taxas de sucesso terapêutico e de reintervenções demonstram a necessidade do seguimento clínico rigoroso desses pacientes a longo prazo. .


Introduction: The management of thoracic aortic disease involving the ascending aorta, aortic arch and descending thoracic aorta are technically challenging and is an area in constant development and innovation. Objective: To analyze early and midterm results of hybrid treatment of arch aortic disease. Methods: Retrospective study of procedures performed from January 2010 to December 2012. The end points were the technical success, therapeutic success, morbidity and mortality, neurologic outcomes, the rate of endoleaks and reinterventions. Results: A total of 95 patients treated for thoracic aortic diseases in this period, 18 underwent hybrid treatment and entered in this study. The average ages were 62.3 years. The male was present in 66.7%. The technical and therapeutic success was 94.5% e 83.3%. The perioperative mortality rate of 11.1%. There is any death during one-year follow- up. The reoperation rates were 16.6% due 2 cases of endoleak Ia and one case of endoleak II. There is any occlusion of anatomic or extra anatomic bypass during follow up. Conclusion: In our study, the hybrid treatment of aortic arch disease proved to be a feasible alternative of conventional surgery. The therapeutic success rates and re- interventions obtained demonstrate the necessity of thorough clinical follow-up of these patients in a long time. .

ABSTRACT

La coartación de aorta es una estrechamiento congénito de la luz aórtica que, generalmente, afecta la porción torácica distal a la emergencia de la arteria subclavia izquierda. Esta condición es de gran importancia, pues predispone al desarrollo de patología cardiovasculares a edades tempranas, lo que se traduce en una alta morbimortalidad. Se reporta el primer caso en Costa Rica, de reparación endovascular de una coartación de aorta, mediante la colocación de un stent recubierto, con parada cardiaca inducida con adenosina. La paciente toleró el procedimiento bien y el gradiente postintervención fue menor de 5 mmHg. Su presión arterial sistémica es 100/60 mmHg y no tiene limitaciones o sintomatología...

ABSTRACT

Coral reef aorta is described as an uncommon entity characterized by the presence of coarse calcifications, which are developed in the visceral aorta. These calcifications grow toward the lumen of the artery and can result in significant stenosis, so that causing malperfusion of the lower limbs, visceral ischemia or hypertension secondary to renal involvement. We report here a case of a 54-year-old patient with coral reef aorta and symptomatic. The clinical presentation of the patient required the surgical approach. A review of literature in major databases was conducted to compare health-related aspects of the disease presentation and management. Coral reef aorta should be considered as the diagnosis for patients with visceral and limbs ischemia. The approach in our case was consistent with other studies previously published in the literature.


A aorta em recife de corais é descrita como uma entidade incomum caracterizada pela presença de calcificações grosseiras, que se desenvolvem na aorta visceral. Essas calcificações crescem em direção ao lúmen da artéria e podem resultar em estenose significativa, gerando má perfusão dos membros inferiores, isquemia visceral ou hipertensão secundária ao acometimento renal. Relata-se aqui o caso de um paciente de 54 anos portador de aorta em recife e sintomático. O quadro clínico do paciente exigiu abordagem cirúrgica. Foi realizada revisão de literatura nas principais bases de dados para comparar os aspectos relacionados à apresentação e à conduta da doença. Em pacientes com sinais de isquemia visceral ou em membros inferiores, deve-se considerar o diagnóstico de aorta em recife de coral. A abordagem, no caso relatado, foi consistente com estudos publicados anteriormente na literatura.
