Aneurisma de seno de valsalva fistulizado a auricula derecha / Fístula of sinus of valsalva aneurysm to the right atrium

Resumen: Los aneurismas de seno de Valsalva son una malformación rara de observar en la práctica clínica. Se presentan a cualquier edad y pueden ser de origen congénito o adquirido. La importancia de su estudio radica en que potencialmente pueden complicarse con rotura y fistulización a otra estructura cardíaca o extracardíaca, con una alta mortalidad asociada. El diagnóstico muchas veces puede ser complejo, pero existen algunos elementos clínicos inespecíficos que pueden orientarnos en su detección y rápido manejo, lo que puede marcar una diferencia en el pronóstico del paciente. Se presenta el caso de un paciente de 49 años con un aneurisma de seno de Valsalva complicado y a continuación una breve revisión del tema.

Abstract: Aneurysms of the sinus of Valsalva are. They occur at any age, either as a congenital or an acquired malformation. They may rupture and form a fístula to other cardiac structures, with a high mortality rate. The clinical case of a 49 year-old patient with a ruptured sinus of Valsalva an a fístula to the right atrium is presented. A brief review of the subject is included.

Concentración de la cirugía de aneurisma de aorta abdominal roto en centros especializados calificados / Concentrating ruptured abdominal aortic aneurysm surgery in specialized centers

Ruptured abdominal aortic aneurysm (RAAA) is an arterial emergency with an overall mortality of 80%-90% secondary to massive hemorrhage. If a patient with RAAA presents in a primary hospital without resolution capacity, survival will depend on early transfer to a center with adequately trained specialists. This article reviews the evidence supporting the centralization of AAAR treatment in qualified centers, specifying the criteria used for the selection of referral centers and the role of a coordinating unit. Our current referral system, which is based primarily on costs, is also described. Patients with AAAR who consult in non-resolving centers should be rapidly transferred to a qualified referral center, following a transfer protocol, and guided by a coordinating unit acting according to technical and established criteria based on results, quality, and costs. Qualified referral centers should have an accredited vascular surgeon and a high institutional aortic surgery volume, adequate infrastructure, endovascular resolution capacity, support services (intensive care, hemodialysis, etc.) and specialized personnel permanently available.

Surgical Repair of a Ruptured Giant Abdominal Aortic Aneurysm in a 16-Year-Old with Takayasu's Arteritis: Case Report and Etiological Review

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.

Ruptured sinus valsalva aneurysm - an uncommon cause of new onset heart failure onset heart failure / Rotura de aneurisma del seno de valsalva: una causa infrecuente de insuficiencia cardíaca aguda

Abstract: A young man presented to the emergency room with symptoms of recent onset heart failure. On physical examination he showed signs of right heart failure and a continuous murmur.

Por ecocardiografía trans esofágica y Angio TAC, se confirmó la presencia de un aneurisma del seno de Valsalva derecho roto con cortocircuito de izquierda a derecha. Se procedió al cierre del aneurisma, confirmando se buen resultado, acompañado de una evolución asintomática 3 meses después de la intervención.

"Overtime Hours Effect" on emergency surgery of acute type A aortic dissection

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.

Late open conversion in ruptured abdominal aortic aneurysm after endovascular repair / Conversão tardia para cirurgia aberta em um aneurisma roto da aorta abdominal após reparo endovascular

Abstract Despite technological advances, the long-term outcomes of endovascular aortic aneurysm repair (EVAR) are still debatable. Although most endograft failures after EVAR can be corrected with endovascular techniques, open conversion may still be required. A 70-year-old male patient presented at the emergency unit with abdominal pain. Twice, in the third and fourth years after the first repair, a stent graft had been placed over a non-adhesive portion of the stent graft due to type Ia endoleaks. In the most recent admission, a CT scan showed type III endoleak and ruptured aneurysm sac. On this occasion the patient underwent late open conversion. The failure was repaired with total preservation of the main endovascular graft body and interposition of a bifurcated dacron graft. This case demonstrates that lifelong radiographic surveillance should be considered in this subset of patients. Late open conversion following EVAR of ruptured abdominal aortic aneurysms can be performed safely.

Resumo Apesar dos avanços tecnológicos, os desfechos de longo prazo do reparo endovascular de aneurismas da aorta abdominal (endovascular aortic aneurysm repair - EVAR) ainda são objeto de debate. Embora a maioria das falhas de endoenxerto após EVAR possam ser corrigidas com técnicas endovasculares, conversão para cirurgia aberta ainda pode ser necessária. Um paciente de 70 anos de idade, do sexo masculino, apresentou-se no serviço de emergência com dor abdominal. Duas vezes, dois e quatro anos após o primeiro reparo, um enxerto foi colocado sobre uma porção não adesiva do stent devido a endoleak tipo Ia. Na mais recente hospitalização, a tomografia computadorizada mostrou endoleak tipo III e ruptura de um saco aneurismático. Nesta ocasião, o paciente foi submetido a conversão tardia para cirurgia aberta. A falha foi tratada com preservação total do corpo principal do enxerto endovascular e interposição de um enxerto tipo Dacron bifurcado. Este caso demonstra que a vigilância radiográfica ao longo de toda a vida deveria ser considerada nesse subgrupo de pacientes. Conversão tardia para cirurgia aberta após EVAR de aneurismas rotos da aorta abdominal pode ser realizada com segurança.

Ruptura traumática de la aorta descendente torácica / Traumatic ruptura of the descending thoracic aorta

Los traumatismos torácicos graves (TT), ya sean abiertos o cerrados, pueden ocurrir secundarios a lesiones por arma de fuego, arma blanca, accidentes de tránsito, caídas de altura o compresiones torácicas por aplastamientos, entre otros y se han transformado en una causa importante de morbilidad y mortalidad, pero son las lesiones vasculares directamente responsables de un 20 a un 25 por ciento del total de las muertes, causadas por estos traumatismos. La mayoría de los afectados por estas lesiones son personas jóvenes previamente sanas, fundamentalmente del sexo masculino. Se presenta un caso clínico de un paciente de 38 años de edad, con antecedentes de salud previos, que durante una riña, sufrió una herida en la región posterior del hemitórax derecho, por debajo del borde inferior de la escápula, penetrante en la cavidad torácica, ocasionada por un objeto corto punzante de fabricación artesanal, cuyo pedazo quedó dentro de esta cavidad, lo cual provocó una lesión de alrededor de 3 cm de longitud, aproximadamente a nivel de la aorta descendente torácica. El paciente fue intervenido quirúrgicamente de manera urgente, y se logró suturar la lesión vascular con éxito, proceder que casi nunca es posible debido al alto índice de mortalidad de este tipo de lesiones, pues la mayoría de las personas fallecen antes de su llegada a un centro especializado de salud(AU)

Severe thoracic traumatisms, either open or close, may occur secondary to injuries caused by firearms, knifes, traffic accidents, falls from height or thoracic compression due to crushing, among others. They have become an important cause of mortality and morbidity but they are vascular injuries directly responsible for 20 to 25 percent of the total number of deaths caused by this type of traumatism. Most of the injuries occurred in healthy young people, mainly men. This is the case of a 38 years-old patient with a history of health problems, who in a street fight, suffered an injury in the posterior region of the right hemithorax, below the lower rim of the scapula. It was a penetrating wound in the thoracic cavity caused by a short sharpened object; a piece of this object was trapped into the cavity and caused a 3 cm long injury, at the level of the thoracic descending aorta. The patient was operated on in an emergency situation and the vascular injury was successfully sutured, a procedure that barely has positive results due to the high mortality rate of this type of injuries. Most of the affected people die before arriving to the specialized health center(AU)

Aorta após endoprótese para aneurisma micótico / Aorta after stent grafting for mycotic aneurysm / Aorta después de endoprótesis para aneurisma micótico

Endopróteses vasculares são atualmente utilizadas no tratamento de diferentes patologias da aorta. Podem salvar a vida de pacientes com comorbidades e virtualmente inoperáveis quando da utilização de técnicas convencionais. Esse manuscrito relata o caso de um paciente de 40 anos, que havia sido previamente tratado de um aneurisma micótico sacular no arco aórtico e que apresentou ruptura da aorta descendente no seguimento de médio prazo. O tratamento da ruptura da aorta descendente também foi realizado através de medidas endovasculares, com sucesso.

Endovascular stent grafting is applied for the treatment of different aortic pathologies in the current medical era. It may be lifesaving in patients with comorbidities and virtually inoperable when adopting conventional techniques. This manuscript reports on a 40-year-old patient, who was previously treated for a mycotic saccular aneurysm at the aortic arch and who presented with a descending aortic rupture at the mid-term follow-up. The descending aortic rupture was also managed successfully by endovascular measures.

Úlcera penetrante de aorta com evolução atípica / Penetrating aortic ulcer with atypical development

A úlcera penetrante de aorta é uma variante da dissecção aórtica clássica que apresenta características histopatológicas peculiares. Estas lesões se desenvolvem a partir de placas ateromatosas ulceradas que se estendem através da íntima. O reparo endovascular é considerado uma alternativa segura e menos invasiva; no entanto, o manejo desta enfermidade ainda constitui um desafio para o cirurgião. Objetivo: Relatar o caso de um paciente do sexo masculino, 61 anos, portador de úlcera de aorta torácica que evoluiu com perfuração e dissecção aórtica, a qual se manteve tamponada durante 13 meses, até o seu tratamento definitivo. Método: As informações necessárias foram obtidas por meio de revisão de prontuário, entrevista com o paciente e registro fotográfico de métodos de diagnóstico por imagem aos quais o paciente foi submetido. Considerações finais: O paciente, embora tardiamente, foi submetido com sucesso ao tratamento endovascular de úlcera penetrante de aorta e evoluiu sem intercorrências graves durante e após o procedimento terapêutico. Cada vez mais casos bem-sucedidos de tratamento endovascular de úlceras e outras doenças da aorta vêm sendo relatados e parece haver uma expectativa da comunidade médica de que, em breve, esta modalidade se firme como o padrão no tratamento destas enfermidades

The penetrating aortic ulcer is a particular variety of the classic aortic dissection with peculiar histological findings. These lesions develop from ulcerating atheromatous plaques that extend through the intima. The endovascular procedure is considered a safe and less invasive method of treatment, but the management of this disease is still seen as a challenge for the surgeon. Aim: To relate a case of a male patient of 61 years old that had an aortic ulcer witch has suffered perforation and produced an aortic dissection. The aortic perforation remained stable during 13 months until the patient has received the definitive treatment. Method: The necessary data was obtained by medical chart review, interview with the patient and photographic register of the image diagnose exams that were performed. Final considerations: The patient, even through with delay, was successful submitted to endovascular treatment for penetrating aortic ulcer and has suffered no severe complications during and after the procedure. Recently more and more well-succeed cases of encovascular treatment for the penetrating ulcer and other pathologies of the aorta have been described and it seems to exist an expectance of the medical community that, shortly, this modality will be recognized as the gold standard to manage these diseases

Ruptured thoracic aortic aneurysm in patient with systemic lupus erythematosus / Aneurisma roto da aorta descendente em paciente com lúpus eritematoso sistêmico

It is reported a ruptured descending thoracic aortic aneurysm in a 25-year-old systemic lupus erythematosus woman who underwent 19 years steroid therapy. She was treated with 2 endovascular stent-grafts, discharged from hospital 13 days after the procedure in good health. Three months later she returned with hemorrhagic shock due to high digestive hemorrhage secondary to an aortic-esophageal fistula. She underwent to an open emergency surgery, and died during the post-operative period.

Paciente de 25 anos, do sexo feminino, portadora de lúpus eritematoso sistêmico, fazendo uso de corticoesteroide havia 19 anos, deu entrada em unidade de emergência com aneurisma roto de aorta torácica descendente. Foi submetida a tratamento endovascular com 2 stents, recebeu alta hospitalar no 13º dia de pós-operatório, em boas condições de saúde. Três meses depois, retornou em choque hemorrágico secundário a hemorragia digestiva alta. Feito o diagnóstico de fístula aorto-esofágica, foi submetida à cirurgia aberta de emergência, indo a óbito durante o período pós-operatório.

Tratamiento endovascular de transecciones agudas de la aorta descendente / Endovascular treatment of acute traumatic aortic rupture

Background: Traumatic rupture of the thoracic aorta as a result from high-speed deceleration injury is associated with a mortality rate of 80 percent to 90 percent at the scene of the accident. Survivors usually have life-threatening injuries to other organ systems. Standard open repair is associated with a high penoperative morbidity and mortality. Endografting offers a less invasive alternative to open surgical repair. Aim: To evaluate results of endovascular management of acute traumatic descending thoracic aortic ruptures. Methods: Between August 2002 and March 2010, patients treated for this trauma were reviewed. Results: 16 patients (fourteen males mean age 42.7 +/- 15.8 years, range 24-74) underwent endovascular treatment of an acute aortic rupture. Associated traumas in fifteen patients were: severe brain (7), spleen (4), liver (1), kidney (3) and large bone (9) injuries. Motor vehicle accidents caused 13 of the injuries and fall from height 3. Rupture was diagnosed with admission CT sean and confirmed by intraoperative angiogram. Patients were treated with thoracic aortic endograft, in 11 cases the left subclavian artery was covered with no need for further revascularization. Technical success was 100 percent, no procedure-related mortality or paraplegia was observed. One patient died 5 days after the procedure due to severe associated injuries. During a mean follow-up of 30.8 months (range 1-80), no deaths, complications or need for further interventions presented. Conclusion: Endovascular treatment of acute traumatic aortic isthmic rupture is encouraging and compares favorably to open surgical approach with low morbidity and mortality rates.

Los accidentes por desaceleración súbita se asocian a transección de la aorta torácica, falleciendo 85-90 por ciento de ellos en el sitio del suceso. Los que sobreviven presentan habitualmente politraumatismo asociado grave, teniendo la reparación quirúrgica convencional de la aorta una alta morbimortalidad. La reparación endovascular es una alternativa menos invasiva y de menor morbi-mortalidad. Objetivo: Analizar los resultados de la reparación endovascular de transecciones agudas de la aorta torácica. Pacientes y Métodos: Se revisan los antecedentes de los pacientes tratados entre agosto de 2002 y marzo de 2010. Resultados: Tratamos 16 pacientes (14 hombres, 42,7 +/- 15,8 años, extremos 24-74) con transección traumática aguda de aorta torácica descendente. Quince presentaban lesiones asociadas: traumatismo encéfalo-craneano (7), fractura de huesos largos (9), laceración esplénica (4), hepática (1), renal (3). La causa del accidente fue vehicular en 13 casos y caída de altura en 3. El diagnóstico fue realizado mediante tomograña axial computada al ingreso y luego angiograña en la sala de operaciones. El tratamiento consistió en la cobertura de la zona de transección mediante el implante de una endoprótesis, siendo necesario cubrir la arteria subclavia izquierda en 11 casos, sin requerir revascularización de la extremidad. El éxito técnico fue 100 por ciento, no hubo mortalidad relacionada al procedimiento. No hubo paraplejia. Un paciente de 60 años fallece al 5to día por lesiones asociadas graves. En el seguimiento alejado a 30,8 meses (1-80) no ha habido complicaciones ni reintervenciones. Conclusión: La cirugía endovascular es una alternativa eficaz y con baja morbimortalidad para el tratamiento de transecciones de la aorta torácica.

Multiple ruptured aneurysm of left sinus of valsalva: A rare entity.

Aneurysm of sinus of Valsalva is a rare congenital cardiac defect that can present with myriad signs and symptoms ranging from trivial to catastrophic events like cardiogenic shock and death. As clinical examination is not entirely reliable and the patient can sometimes be so ill as to preclude cardiac catheterization, echocardiography has become the definitive investigative tool not only to define and diagnose the lesion but also to quantify its severity. The following is a case report of multiple aneurysms of the left aortic sinus of Valsalva rupturing into the left ventricle. Diagnosis is made on multi plane transesophageal echocardiography and color Doppler regarding precise identification of structural anomalies and shunt locations for perioperative assessment and definitive treatment is surgical repair.

Enfoque interdisciplinario en el tratamiento del Síndrome de Marfan: resultados a 17 años / Interdisciplinary approach of Marfan Syndrome: a 17-year experience

Introducción: el Síndrome de Marfan (SM) es una enfermedad genética de baja prevalencia (1/5.000) individuos). Esta entidad posee características cardiovasculares, esqueléticas y oculares bien definidas. El pronóstico depende fundamentalmente de la dilatación de la raíz aórtica que provoca disección y/o ruptura de la misma. Hay gran desconocimiento sobre este síndrome por parte de los médicos de todas las especialidades. Con la formación de un equipo interdisciplinario diseñamos un registro sobre esta patología, relevando el comportamiento clínico y quirúrgico. Objetivo: registrar la información clínica y evolutiva de los pacientes con SM derivados de diversos lugares de nuestro país a nuestro centro con el fin de lograr una mejor atención de esta patología y detectar la presencia de dilatación de la raíz aórtica. Material y métodos: entre 1992 y 2009 se incluyeron pacientes con diagnóstico de SM de acuerdo a los criterios internacionales establecidos en Ghent. Fueron evaluados por traumatólogos, cardiólogos, cirujanos cardiovasculares, oftalmólogos, nutricionistas, neumonólogos y psicólogos y controlados periódicamente con un programa preestablecido recibiendo tratamiento preventivo médico y/o quirúrgico. Resultados: se evaluaron 273 pacientes, 145 de sexo masculino (53,5%). La edad promedio fue de 25,7 años (2 a 70 años). Las manifestaciones diagnósticas cardiovasculares correspondieron en orden decreciente a: aneurisma de aorta torácica 84 p (30,7%), insuficiencia valvular aórtica 47 p (17,2%), prolapso de válvula mitral 30 sujetos (10,9%) e insuficiencia mitral en 28 (10,2%). 63 % (90 pacientes) requirió cirugía de reemplazo de aorta ascendente. 76 pacientes en nuestro Hospital, el 84 % de las cirugías fueron programadas. Conclusión: la constitución de un equipo interdisciplinario permitió controlar un importante número de pacientes con SM con la detección de un número significativo de casos pasibles de tratamiento preventivo del aneurisma de aorta torácica.

Introduction: Marfan syndrome is a genetic disorder of low prevalence (1/5,000 subjects). This disorder has well defined cardiovascular, skeletal and ocular features. Its prognosis depends mainly on the aortic root dilation leading to its disection and/or rupture. This Syndrome is not well known among physicians of all specialties. In order to study the clinical and surgical characteristics of this disorder, we form an interdisciplinary team and design a registry. Objective: To register the clinical information and evolution of patients with Marfan Syndrome referred from different areas of our country to our Hospital in order to get a better attention of this disorder and to detect the presence of thoracic aorta dilation. Methods: Between 1992 and 2009, patients with Marfan Syndrome were included according to the international criteria established in Ghent. An interdisciplinary team formed by: traumatologists, cardiologists, cardiovascular surgeons, oftalmologists, specialists in nutrition, neumonologists and psychologists, evaluated and controlled the patients periodically with a pre set program receiving medical and/or surgical treatment. Results: it were evaluated 273 patients, 146 male (53,5%). Average age was 25.7 years (2-70 years old). Cardiovascular manifestations were in decreasing order: thoracic aorta aneurysms 84 p (30.7%), aortic valve regurgitation 47p (17.2%), mitral valve prolapse 30p (10.9%) and mitral regurgitation 28 p (10.2%), 90 patients (63%) required replacement of the ascending aorta, 76 were performed in our Hospital, and 84% of the procedures were scheduled. Conclusions: the formation of an interdisciplinary team allowed to control an important number of patients with Marfan Syndrome detecting a significant amount of cases which could be treated with preventive surgery of the thoracic aorta aneurysms, main cause of early mortality.

Aneurisma del seno de Valsalva roto: informe de casos y revisión de la literatura / Sinus of Valsalva aneurysm with rupture: case report and literature review

Introducción: El aneurisma del seno de Valsalva es una dilatación que se origina por adelgazamiento de la unión de la capa media aórtica y el anillo fibroso; de origen adquirido y más frecuentemente congénito. El seno coronario derecho es el más afectado y la rotura es la complicación más común. Casos clínicos: Presentamos dos casos de aneurisma del seno de Valsalva roto a cavidades derechas con insuficiencia cardiaca severa, que constituyeron 0.4 % del total de cirugías cardiacas realizadas en un año en el Hospital de Especialidades, Centro Médico Nacional de Occidente, Guajalajara, Jalisco. Caso 1: hombre de 27 años con disnea de pequeños esfuerzos, disnea paroxística nocturna, ortopnea, fibrilación auricular paroxística, soplo diastólico, hepatomegalia y edema de miembros inferiores. Caso 2: hombre de 33 años con disnea de pequeños esfuerzos, disnea paroxística nocturna, ortopnea, soplo diastólico, insuficiencia renal aguda e insuficiencia hepática congestiva. La resolución quirúrgica consistió en resección del aneurisma y cierre del defecto con parche de dacrón, preservando la válvula aórtica. Ambos casos sobrevivieron. Conclusiones: La presencia de insuficiencia cardiaca y cambios auscultatorios súbitos obligan a sospechar aneurisma del seno de Valsalva roto. La ecocardiografía es suficiente para diagnosticar aneurisma del seno de Valsalva, sus complicaciones, repercusión y orientación quirúrgica. Cuando es asintomático existe riesgo de expansión, rotura, insuficiencia cardiaca, endocarditis, embolia y muerte súbita, lo que justifica la resolución quirúrgica, la cual tiene baja mortalidad a corto y largo plazo.

BACKGROUND: The sinus of Valsalva aneurysm (SVA) is a small dilatation caused by a separation between the aortic media and annulus fibrosus. Its origin may be either acquired or congenital. The right coronary sinus is most frequently affected, with the most common complication being rupture. CLINICAL CASES: We report two cases of SVA complicated with rupture to the right cavities with severe cardiac failure, which represents 0.4% of the total cardiac surgeries performed during the past year in our hospital. Case #1: We present the case of a 27-year-old male with low-effort dyspnea, nocturnal paroxysmal dyspnea, orthopnea, paroxysmal atrial fibrillation, diastolic murmur, hepatomegaly and edema of the lower extremities. Case #2: We present the case of a 33-year-old male with low-effort dyspnea, nocturnal paroxysmal dyspnea, orthopnea, diastolic murmur, severe kidney insufficiency and congestive hepatic insufficiency. Surgical resolution in both cases consisted of aneurysm resection and closure of the defect with a Dacron patch, preserving the aortic valve. Both patients survived. CONCLUSIONS: Cardiac failure and sudden auscultation changes suggest the possibility of SVA rupture. Echocardiography is sufficient to diagnose SVA, its complications, repercussions, and surgical options. SVA, even if asymptomatic, has potential risks of expansion, rupture, cardiac failure, endocarditis, embolism and sudden death. This justifies surgical correction, with a low mortality rate in both the short- and long-term.

Aneurisma del cayado aórtico roto: Reparación exitosa en un solo período de paro circulatorio / Complete repair in a single period of circulatory arrest of a ruptured atherosclerotic aortic arch aneurysm: Report of one case

The aortic arch aneurysm is a complex disease with a growing incidence in our population. We report a 64 year-old female with an atherosclerotic aortic arch aneurysm with a maximum diameter of 9.4 cm and evidence of contained rupture. We performed a complete aortic arch replacement in a single period of 100 minutes of circulatory arrest with deep hypothermia and brain protection with anterograde cerebral perfusión through the right axillary artery. The patient had a complete recovery without evidence of neurological damage and was extubated on the next morning. One year later, the patient is asymptomatic and the peri-aortic haematoma was completely reabsorbed.

Tratamiento endoluminal en aneurisma de aorta abdominal roto / Intraluminal treatment of ruptured abdominal aortic aneurysms

The most frequent complications of any aneurysm is rupture. Consequently there is a general rull that aneurysms should be treated when diagnosed because the odds of survival after rupture are poor... The authors describe the immediate repair using the intraluminal approach, with special reference to indications and results using this procedure. An illustrative and well documented case is presented.
