RESUMO

Abstract Coronary subclavian steal syndrome is an uncommon cause of angina in patients with a previous coronary artery bypass graft procedure. The patient had chest pain with the exertion of the left upper limb, difference in blood pressure between the left and right arm, occlusion at the ostium of the left subclavian artery. He underwent carotid subclavian bypass surgery that was successful in relieving symptoms. On the other hand, the patient had an embolic stroke related to the procedure and further assessment may be necessary.

RESUMO

PURPOSE OF REVIEW: Among the most common causes of cardiac syncope are arrhythmias and ischemic heart disease, both of which can coexist. The purpose of this review is to discuss the main causes of cardiac and vascular syncope related to atherosclerosis, its epidemiological and clinical aspects, warning signs, and initial approach. RECENT FINDINGS: Cardiac syncope may have a frequency of up to 34% in elderly people. Atherosclerosis-related causes of cardiac and vascular syncope may be due to cardiac arrhythmia and/or structural impairment of the heart or arteries. Late ventricular tachycardia and late-onset high-grade atrioventricular block associated with myocardial ischemia may occur with syncope, which is related to higher mortality. Besides ventricular dysfunction, concentric remodeling is also a prognostic factor. In calcific degenerative aortic stenosis, syncope carries a worse prognosis than the other cardinal signs. Cardiac syncope has a high recurrence and mortality rate. There are red flag alerts that must be considered in risk stratification.

RESUMO

ABSTRACT Objective: To describe an infant with craniofacial microsomia and recurrent respiratory distress associated with aberrant right subclavian artery in order to review its most frequent congenital anomalies and alert the pediatrician to its rarer and more severe complications. Case description: This case report involves an 18-month-old male infant, only son of non-consanguineous parents. At birth, the child presented craniofacial dysmorphisms (facial asymmetry, maxillary and mandibular hypoplasia, macrostomia, grade 3 microtia, and accessory preauricular tag) restricted to the right side of the face. Additional tests showed asymmetric hypoplasia of facial structures and thoracic hemivertebrae. No cytogenetic or cytogenomic abnormalities were identified. The patient progressed to several episodes of respiratory distress, stridor, and nausea, even after undergoing gastrostomy and tracheostomy in the neonatal period. Investigation guided by respiratory symptoms identified compression of the esophagus and trachea by an aberrant right subclavian artery. After surgical correction of this anomaly, the infant has not presented respiratory symptoms and remains under multidisciplinary follow-up, seeking rehabilitation. Comments: Craniofacial microsomia presents a wide phenotypic variability compared to both craniofacial and extracraniofacial malformations. The latter, similarly to the aberrant right subclavian artery, is rarer and associated with morbidity and mortality. The main contribution of this case report was the identification of a rare anomaly, integrating a set of malformations of a relatively common condition, responsible for a very frequent complaint in pediatric care.

RESUMO Objetivo: Descrever lactente com microssomia craniofacial e desconforto respiratório recorrente associado à artéria subclávia direita aberrante, com o intuito de revisar as anomalias congênitas mais frequentes e alertar o pediatra sobre suas complicações mais raras e de maior gravidade. Descrição do caso: Lactente do sexo masculino, 18 meses de idade e filho único de casal não consanguíneo. Ao nascimento, foram observadas dismorfias craniofaciais (assimetria facial, hipoplasia maxilar e mandibular, macrostomia, microtia grau 3 e apêndice na linha trago-oral) restritas ao lado direito da face. Os exames complementares evidenciaram hipoplasia assimétrica da face e hemivértebras torácicas. Não foram identificadas anormalidades citogenéticas ou citogenômicas. O paciente evoluiu com diversos episódios de desconforto respiratório, estridor e náuseas, mesmo tendo realizado gastrostomia e traqueostomia no período neonatal. A investigação direcionada para os sintomas respiratórios identificou a compressão de esôfago e traqueia por uma artéria subclávia direita aberrante. Após a correção cirúrgica dessa anomalia, o lactente não tem apresentado sintomas respiratórios e mantém seguimento multidisciplinar buscando reabilitação. Comentários: A microssomia craniofacial apresenta grande heterogeneidade fenotípica em relação às malformações tanto craniofaciais como extracraniofaciais. Estas últimas, como a artéria subclávia direita aberrante, são mais raras e associadas à morbimortalidade. A principal contribuição deste relato de caso foi o reconhecimento de uma anomalia rara, integrando um conjunto de malformações de uma condição relativamente comum e sendo responsável por uma queixa muito frequente no atendimento pediátrico.

RESUMO

Subclavian steal syndrome is a group of symptoms resulting fromretrograde flow in the vertebral artery, "stealing" blood from the posterior intracranial circulation and other territories, caused by stenosis or occlusion of the subclavian artery proximal to the origin of the same vertebral artery, or even of the brachiocephalic trunk. Most of the time, it is an incidental finding in patients with other conditions or cerebrovascular risk factors. We report a series of 29 patients with an angiographic diagnosis, in which 7 received treatment (all endovascular), all with symptoms directly related to this condition. Advanced age, systemic arterial hypertension, diabetes mellitus, smoking and stroke were comorbidities frequently related. Six patients improved completely after the procedure and one remained with vertigo.

RESUMO

Mortality from penetrating traumas involving the subclavian vessels can be as high as 60% in pre-hospital settings. Operating room mortality is in the range of 5-30%. This paper presents a case in which a strategy for damage control was employed for a patient with an injury to the origin of the left subclavian artery, using subclavian ligation, with no need for any other intervention, and maintaining viability of the left upper limb via collateral circulation. The authors also review surgical approaches and treatment strategies with a focus on damage control in subclavian vessel injuries.

RESUMO

When the proximal occlusion or stenosis of the subclavian or of the brachiocephalic artery may require distal arterial filling through reversal flow from the vertebral artery, causing clinically significant blood supply reduction to the brainstem, it is called subclavian steal syndrome (SSS). We report a 54-year-old male patient who presented with multiple episodes of syncopes and vascular claudication due to right SSS. He underwent an angioplasty, evolving with complete improvement of the symptoms. We review the clinical presentation, the diagnosticmethods, and the treatment options of the disease.

RESUMO

Abstract Introduction: The aim of this study was to examine the association of inter-arm systolic blood pressure difference (IASBPD) with carotid artery stenosis, subclavian artery stenosis and vertebral artery stenosis in patients who underwent carotid endarterectomy. Methods: A total of 141 patients (29 females, 112 males; mean age 71.2±10.4 years; range 47 to 92 years) who underwent carotid endarterectomy between September 2010 and December 2017 were retrospectively evaluated. We classified patients into four groups according to the IASBPD ˂ 10 mmHg, ≥ 10 mm Hg, ≥ 20 mmHg and ≥ 30 mmHg. The stenosis of both subclavian and vertebral arteries was considered as ≥ 50%. Results: Of the 141 patients, 44 (31.2%) had ≥ 10 mmHg, 29 (20.5%) had ≥ 20 mmHg and 4 (2.8%) had ≥ 30 mmHg of IASBPD. 26 patients (18.4%) were diagnosed with significant subclavian artery stenosis and 18 (69.2%) of them had more than 20 mmHg of IASBPD. Of the 29 patients with IASBPD ≥ 20 mmHg, 19 patients (65.5%) had a significant subclavian artery stenosis. We found a significant correlation between preoperative symptoms and subclavian artery stenosis (P=0.018) and overall perioperative stroke was seen more frequently in patients with subclavian artery stenosis (P=0.041). A significant positive correlation was observed between vertebral artery stenosis and subclavian artery stenosis (P=0.01). Conclusion: Patients who were diagnosed with both subclavian artery stenosis and IASBPD (≥ 20 mmHg) had a higher risk of postoperative stroke and death, had higher total cholesterol, LDL-C, blood creatinine level, and were more symptomatic.

RESUMO

Abstract The lateral costal artery has sometimes been identified as the culprit for the "steal phenomenon" after coronary artery bypass grafting, besides being occasionally used for myocardial revascularization. Its branches make anastomoses with the internal thoracic artery through lateral intercostal arteries. We aim to report, on three cases, the clinical significance of a well-developed lateral costal artery after coronary artery bypass grafting. Two out of three patients who underwent coronary artery bypass graft surgery in our center between June 2010 and August 2017, applied to us with stable angina pectoris, while the third one was diagnosed with acute coronary syndrome after applying to the emergency department. In coronary cineangiography, in all three cases, a well-developed accessory vessel arising from the proximal 2.5 cm segment of the left internal thoracic artery coursed as far as the 6th rib was detected, and it was confirmed to be the lateral costal artery. A stable angina pectoris in two of the patients was thought to be the result of steal phenomenon caused by the well-developed lateral costal artery. In the two cases with stable angina pectoris the lateral costal artery was obliterated via coil embolization. In the other case with the proximal left anterior descending artery stenosis, before percutaneous coronary intervention, the lateral costal artery was obliterated via coil embolization and the occluded subclavian artery was stented. Routine visualization in cineangiography and satisfactory surgical exploration of the left internal thoracic artery could be very helpful to identify any possible accessory branch of the left internal thoracic artery like the lateral costal artery.

RESUMO

Este relato de caso mostra os perigos que uma diferença significativa assintomática na pressão arterial pode trazer à Implantodontia. Paciente do sexo feminino com 75 anos de idade, com perdas de elementos dentais na região posterior de maxila, recebeu como plano de tratamento cirurgias de enxertia e posterior instalação de implantes. Exames pré-operatórios e avaliação cardiológica foram requisitados, sendo autorizadas as cirurgias. Dois atos cirúrgicos foram realizados sem intercorrências. Na terceira cirurgia, no pré-operatório, constatou-se uma diferença de pressão arterial entre os braços direito e esquerdo quando optou-se pelo cancelamento da cirurgia e novo encaminhamento com urgência ao cardiologista em posse do relatório clínico. A pressão arterial mais baixa no braço esquerdo era causada por uma estenose na artéria subclávia com risco aumentado para acidentes vasculares e morbidade cardíaca. Uma angioplastia foi realizada com a instalação de stent, medicações anti-hipertensivas foram mantidas e um antiagregante plaquetário foi introduzido. A paciente foi liberada para continuidade de seu tratamento, com orientações do cardiologista e cirurgião vascular a serem seguidas. Diante do ocorrido e das observações apontadas na literatura pesquisada, pôde-se concluir que o cirurgião terá um melhor panorama das condições físicas dos pacientes se na anamnese ele tomar como rotina a correta aferição da pressão arterial nos dois braços e, diante de qualquer anormalidade, fazer os encaminhamentos necessários para sua segurança e de seus pacientes.

This case report demonstrates how a significant difference at the interarm blood pressure can bring risks to implant dentistry. A 75 years-old female patient with loss of posterior maxillary teeth received a treatment planning grafting surgeries and further implant placement. The pre-operative exams and a cardiologic evaluation were requested, and dental surgeries authorized. The first two separate operations were made without complications. However, in the third surgical appointment, a high difference in blood pressure was detected between the left and right arms. In this way, the surgery was cancelled and the patient urgently referred to the physician. The medical report demonstrated low blood pressure at the left arm caused by the subclavian steal syndrome with risk of vascular accident and cardiac morbidity. An angioplasty was made and a stent was placed, in addition to antihypertensive medications. A platelet anticoagulant was introduced. The patient was released for dental procedures under guidance of the cardiologist and the vascular surgeon. It can be concluded that routine check of blood pressure in both arms can better screen the patient's physical condition and to improve necessary referrals for the patient's safety.

RESUMO

Introduction: The subclavian steal syndrome is characterized by the vertebral artery flow inversion, due to a stenotic lesion in the origin of the subclavian artery. The Coronary-subclavian Steal Syndrome is a variation of the Subclavian Steal Syndrome and is characterized by inversion of flow in the Internal Thracic artery that has been used as conduct in a myocardial revascularization. Its diagnosis must be suspected in patients with difference in pulse and arterial pressure in the upper limbs, that present with angina pectoris and that have done a myocardial revascularization. Its treatment must be a surgical bypass or a transluminal angioplasty. Objective: The objective is to show the left subclavian artery stenting as a safe and effective method to treat the coronary-subclavian steal syndrome. Methods: Historical prospective, non-randomized trial, through revision of the hospital records of the patients treated with the stenting of the left subclavian artery, from January 2006 to September 2012. Results: In the mentioned period, 4.291 miocardial revascularizations were performed with the use of the left mammary artery, and 16 patients were identified to have the Coronary-subclavian steal syndrome. All of them were submitted to endovascular treatment. The success rate was 100%; two patients experienced minor complications; none of them presented with major complications. Eleven of the 16 patients had ultrassonographic documentation of patent stent for at least one year; two patients lost follow up and other two died. Conclusion: The stenting of the left subclavian artery is a good option for the treatment of the Coronary-subclavian Steal Syndrome, with high level of technical and clinical success. .

Introdução: A síndrome do roubo de subclávia caracteriza-se por inversão de fluxo na artéria vertebral, decorrente de lesão estenótica na origem da artéria subclávia. A síndrome do roubo coronário-subclávio é uma variante da síndrome do roubo de subclávia e caracteriza-se por inversão de fluxo na artéria torácica interna que foi usada como conduto na revascularização do miocárdio. Seu diagnóstico deve ser suspeitado em pacientes com diferença de pulso ou pressão em membros superiores que apresentem quadro anginoso e com histórico de revascularização miocárdica. Seu tratamento pode ser realizado através de bypass cirúrgico ou por meio de angioplastia transluminal percutânea. Objetivo: O objetivo deste artigo é mostrar a angioplastia com stent da artéria subclávia esquerda como um tratamento efetivo e seguro da síndrome do roubo coronário-subclávio. Métodos: Estudo prospectivo histórico, não randomizado, através da revisão de prontuários dos pacientes submetidos a angioplastia de artéria subclávia, no período de Janeiro de 2006 a Setembro de 2012. Resultados: Foram realizadas neste período, 4.291 revascularizações miocárdicas com uso de torácica interna esquerda, sendo identificados 16 pacientes portadores da síndrome do roubo coronário-subclávio. Todos foram submetidos a tratamento endovascular. O índice de sucesso terapêutico foi de 100%; dois pacientes experimentaram complicações menores; nenhum apresentou complicações maiores. Do total, 11 pacientes apresentavam documentação ultrassonográfica de stent pérvio por pelo menos um ano; dois pacientes perderam seguimento e outros dois foram a óbito. ...

RESUMO

Relata-se o caso de paciente de 55 anos de idade, com quadro de síncope com perda da consciência após esforço físico com os membros superiores em seu ambiente de trabalho. A paciente foi encaminhada à cardiologia para investigação, sendo detectado ao ecocolordoppler de carótidas e vertebrais fluxo reverso na artéria vertebral esquerda, que sugeriu obstrução a montante da artéria subclávia esquerda. Encaminhada à cirurgia vascular, foi submetida à angiografia dos vasos do pescoço, a qual confirmou oclusão no segmento proximal da artéria subclávia esquerda. Foi submetida à angioplastia transluminal percutânea e implante de stent com reparo da lesão e restabelecimento do fluxo, com bom resultado terapêutico.

We report the case of a 55-year-old female patient with syncope and loss of consciousness after exercising her upper extremities in the workplace. The patient was referred for cardiac evaluation. Doppler ultrasound examination of the carotid and vertebral arteries revealed reversed flow to the left vertebral artery, suggesting obstruction of the left subclavian artery. The patient was then referred for vascular surgery and underwent angiography of the neck vessels, which confirmed occlusion of the proximal left subclavian artery. She underwent percutaneous transluminalarterial angioplasty and stenting to repair the injury and restore the blood flow, with good therapeutic results.

RESUMO

O fenômeno do roubo coronário-subclávio é definido como o fluxo sanguíneo invertido de uma artéria coronária, por meio de enxerto de artéria mamária interna em direção à subclávia médio-distal, e ocorre devido à estenose significativa ou oclusão total da porção proximal desta última. É uma causa rara, mas significante, de isquemia cardíaca após cirurgia de revascularização miocárdica e pode originar uma síndrome de mesmo nome e com manifestações típicas. Relatou-se o caso de um paciente com esta enfermidade, que foi submetido à angioplastia percutânea com implante de stent. Também revisou-se a literatura a respeito.

The phenomenon of coronary-subclavian steal is defined as the reversed blood flow in a coronary artery, through internal mammary artery graft towards medial-distal subclavian artery, which happens due to severe stenosis or total occlusion of the proximal portion of the latter. It is a rare but significant cause of cardiac ischemia after coronary artery bypass surgery and it can cause a syndrome of the same name and with typical manifestations. We have reported the case of a patient with this disease, who underwent percutaneous angioplasty with stent implantation, and we also reviewed the literature on the subject.

RESUMO

A 54-year male with previous triple vessel coronary artery and aorto-bifemoral bypass graft surgeries complained of crescent angina. Stress induced myocardial ischemia on echocardiography was demonstrated. We performed direct stenting of a saphenous vein graft to the right coronary artery, via right radial approach. Subsequently stenting of a severe left subclavian artery proximal stenosis was performed via right brachial approach in order to relieve an overt myocardial ischemia in the territory supplied by a patent left internal mammary artery graft originated distally to the left subclavian stenosis. The finding of a total left axillary artery occlusion complement the pathogenesis of myocardial ischemia produced by limited anterograde flow and not driven by the common flow reversal mechanism of a typical coronary-subclavian steal syndrome.

Se trata de un paciente masculino de 54 años de edad, con antecedentes de cirugía de revasuclarización miocárdica por enfermedad coronaria trivascular, así como puentes aortobifemorales. Se presentó en nuestro centro aquejando de angina de pecho, de patrón creciente. Se demostró la existencia de isquemia miocárdica, mediante ecocardiografía con estrés farmacológico. Realizamos una angioplastia con stent a un puente de safena inversa a la coronaria derecha por vía radial derecha. Posteriormente debido a una estenosis proximal severa de la arteria subclavia izquerida, implantamos un stent mediante vía braquial derecha, con la idea de mejorar la isquemia existente en el territorio previamente revascularizado por un puente de arteria mamaria izquierda, que se originaba distalmente a la estenosis de la arteria subclavia. El hallazgo de una oclusión total crónica a nivel de la arteria axilar izquierda completó la patogénesis de la isquemia miocárdica no condicionada por robo al flujo coronario, como tradicionalmente sucede en el síndrome de robo subclavio coronario. En este caso particular, el mecanismo isquémico fue debido al compromiso anterógrado de flujo, provocado por la estenosis severa de la arteria subclavia.

RESUMO

Objetivo. Descrever dados clínicos, laboratoriais e de anatomia patológica em uma paciente portadora de arteritede Takayasu coexistente com tuberculose. Enfatiza-se o papel dos estudos de autopsia para revelar associaçõesentre enfermidades que podem permanecer sem diagnóstico ou não informadas, quando se baseia exclusivamenteem dados clínicos.Relato do caso. Descreve-se o caso de mulher com 17 anos de idade, portadora de arterite de Takayasu coexistentecom sequelas de tuberculose no pulmão e em linfonodos. Ela apresentou síncope e ausência de pulso nobraço direito provavelmente devido à síndrome do roubo da subclávia.Conclusão. A associação causal entre a arterite de Takayasu e tuberculose tem sido sugerida, mas o papel doMycobacterium tuberculosis não está completamente esclarecido nessa condição. Essa arterite é rara em nossopaís, mas sua prevalência vem aumentando. Embora a freqüência de tuberculose seja elevada no Brasil, estudos deautopsia sobre a arterite de Takayasu concomitante com tuberculose têm sido muito raramente publicados.

Objective. Clinical, laboratory and pathology findings are described in a patient with Takayasu?s arteritis coexistingwith tuberculosis, and the role of the autopsy studies is emphasized to detect associations between diseases, whichmay persist underdiagnosed or underreported if strictly based on the clinical data.Case report. The case of a 17-year-old female with Takayasu?s arteritis coexistent with lung and lymph nodesequels of tuberculosis is described. She presented with syncope and absence of pulse in the right arm likely due tosubclavian steal syndrome.Conclusion. Causal association between Takayasu?s arteritis and tuberculosis has been suggested, but the pathogenicrole of Mycobacterium tuberculosis is not entirely clear in this condition. This arteritis is rare in our country, but itsprevalence has increased. Although the prevalence of tuberculosis is high in Brazil, autopsy studies of simultaneousTakayasu?s arteritis and tuberculosis have been very rarely published.

RESUMO

O objetivo deste trabalho é apresentar o teste de esforço com o dinamômetro isocinético na avaliação objetiva da isquemia funcional da doença arterial oclusiva de membros superiores (DAOMS). Reuniu-se 23 pacientes com DAOMS unilateral, no grupo 1. Sete pacientes, sem DAOMS foram selecionados como o grupo controle (grupo 2). Os membros testados sem DAOMS do grupo 1 e do grupo 2 não apresentaram diferença estatística. A comparação de cada membro dos pacientes do grupo 1, com e sem DAOMS mostrou que os membros com DAOMS apresentaram desempenho significativamente menor que os membros sem lesão. Este teste permite a avaliação objetiva da limitação causada pela DAOMS de forma segura e objetiva.

The objective of this work is to present the results of a stress test using an isokinetic dynamometer in patients with occlusive arterial disease in upper limbs (OADUL). Group 1 has 23 patients with unilateral subclavian occlusive disease. Seven patients, without OADUL, were included in a control group (group 2). No statistically difference was found in all parameters studied between limbs without OADUL in groups 1 and 2. So, each arm in group 1 (with and without OADUL) were tested. For all these parameters, the SOD limbs presented significantly lower values than the control limbs. This test gives an objective grade of limitation of the muscle function in patients with OADUL.
