ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

A síndrome do roubo da subclávia refere-se a uma desordem vascular na qual ocorre inversão do fluxo de sangue da artéria vertebral ipsilateral, decorrente de uma estenose proximal à sua origem, geralmente uma oclusão da artéria subclávia ou, mais raramente, do troncobraquiocefálico. É uma doença relativamente rara, relatadaem aproximadamente 6% dos pacientes assintomáticos com sopros cervicais. O Doppler pulsado (PW) é útil na análiseda artéria vertebral, registrando informações capazes de identificar a presença da Síndrome do Roubo da Subclávia. Com base nas alterações hemodinâmicas da artéria vertebralavaliadas pelo estudo com Doppler espectral, pode ser classificada nos tipos 1 (oculto), 2 (intermitente ou parcial)e 3 (completo). Com o advento da angioplastia transluminal percutânea e, em seguida, dos stents, muitos advogam essa combinação de procedimentos como o tratamento de escolha dos casos sintomático dessa síndrome.

ABSTRACT

Paciente femenina de 46 años de edad, con antecedentes de hipertensión arterial y fumadora habitual. Desde hace 2 años presenta episodios aislados y breves de vértigos, inestabilidad postural, sensación de desfallecimiento sin alteraciones de la conciencia, después de realizar ejercicios del brazo izquierdo. El examen neurológico muestra asimetría de pulsos carotídeos y radiales. El doppler extracraneal reveló alteraciones ateroscleróticas en ambos ejes carotídeos, con estenosis derecha del 50 %, disminución del flujo de la arteria vertebral izquierda y obstrucción proximal de la arteria subclavia izquierda proximalmente. El síndrome del robo de la subclavia es una entidad poco frecuente, su diagnóstico es clínico y se demuestra mediante doppler o angiografía. El tratamiento debe ser decidido individualmente en cada caso.


A 46 year-old female patient with a history of hypertension and regular smoker complained of isolated and brief episodes of dizziness, postural instability, faint feeling without altered consciousness, after exercise the left arm for 2 years. Her neurological examination showed asymmetry of carotid and radial pulses. Her extracranial doppler revealed carotid atherosclerotic changes in both axes, with 50 % right stenosis, decreased flow of the proximal left vertebral artery and obstruction of the proximal left subclavian artery. Subclavian Steal Syndrome is a rare condition. Its diagnosis is clinical and it is demonstrated by Doppler or angiography. Treatment should be determined individually in each case.

ABSTRACT

It is the obstruction or estenosis of an artery’s proximal segment, which is close to the origin the vertebral artery. This causes blood flow inversion within the ipsilateral artery. An increase in the irrigation demands of the artery may cause TIA in the posterior circulation, which is denominated as subclavian steal syndrome. In these cases, contralateral circulation may contribute to prevention of several events due to hypoperfusion. In the case in which a subclavian estenosis accompanied by alteration in blood flow in the contralateral artery arises, symptoms corresponding to the irrigation area affected will be generated.


Se denomina de esta manera a la obstrucción o estenosis del segmento proximal de dicha arteria, cercano al origen de la arteria vertebral, lo que provoca inversión del flujo de la arteria vertebral ipsilateral. Un incremento en la demanda de la irrigación de la arteria vertebral puede provocar un AIT en la circulación posterior, o “robo de la subclavia”. De acontecer esto, existe el aporte de la circulación contra lateral que puede prevenir los diversos eventos debido a la hipoperfusión. De coexistir una estenosis de la subclavia con alteraciones de la circulación contralateral, se generaran los síntomas respectivos al área de irrigación afectada.

ABSTRACT

Percutaneous transluminal angioplasty with or without stenting of steno-occlusions in the supra-aortic arch vessels in aortoarteritis is associated with suboptimal results and higher restenosis rates, particularly in those with diffuse disease. We report two cases of stand-alone cutting balloon angioplasty for patients who presented with critical stenosis of the common carotid artery, and occlusion of the subclavian artery, respectively.

ABSTRACT

Subclavian steal syndrome refers to the association of neurological symptoms related to vertebrobasilar insufficiency and the phenomenon of subclavian steal. We report the case of a 63 year-old male patient that presented subclavian steal syndrome and severe proximal (80 percent) stenosis of the left subclavian artery. The patient was submitted to percutaneous transluminal angioplasty and stenting on the left SA. The procedure was well tolerated and immediately afterwards, there was complete remission of the symptoms and of the phenomenon of subclavian steal evaluated by angiography and transcranial doppler. We propose that percutaneous transluminal angioplasty with stenting placement is a good therapeutic option for subclavian steal syndrome

ABSTRACT

Os autores apresentam o caso de um paciente de 65 anos de idade, diabético e coronariopata grave, submetido à revascularizaçao miocárdica há 10 anos, com duas pontes de safena (ocluída) e uma ponte de mamária pérvia, com sintomas de hipofluxo. Procurou o serviço de emergência do Hospital de Base com clínica de angina instável e síndrome do roubo de artéria subclávia. Foi submetido a estudo angiográfico, que confirmou estenose de artéria carótida esquerda e de artéria subclávia direita obstruçao da artéria subclávia esquerda na sua origem. Devido ao risco cirúrgico alto foi proposta angioplastia transluminal que proporcionou a resoluçao do quadro clínico.

ABSTRACT

A síndrome do roubo da subclávia é doença cérebro-vascular incomum, que pode ser tratada por meio de técnicas endovasculares. São apresentados três casos dessa entidade, submetidos a angioplastia percutânea transluminar, fazendo-se breve revisão da literatura. Dois pacientes permanecem assintomáticos 23 e 30 meses, respectivamente, após o tratamento. Houve recidiva da lesão em um dos pacientes, 12 meses após o procediemnto. Pela baixa morbidade e pelos bons resultados técnicos e clínicos a angioplastia percutânea transluminar deve ser o método de escolha para o tratamento da síndrome do roubo da subclávia.

ABSTRACT

Os autores apresentam o caso de um paciente submetido a cirurgia de revascularizaçäo miocárdica há 10 anos com anastomose da artéria mamária interna esquerda-artéria coronária descendente anterior e que há cerca de 2 meses voltou a apresentar dor precordial típica progressiva. Foi realizado estudo hemodinâmico que revelou anastomose mamária-coronária patente e lesäo obstrutiva severa da artéria subclávica esquerda, caracterizando-se assim a síndrome do roubo coronária-subclávia. O paciente foi entäo submetido a angioplastia transluminal percutânea da artéria subclávia esquerda com sucesso ocorrendo remissäo dos sintomas. Obteve-se o acompanhamento clínico do paciente, assintomático do ponto de vista cardiológico por 1 ano e 8 meses, quando entäo veio a falecer em decorrência de acidente vascular encefálico. Os autores recomendam atençäo especial as lesöes obstrutivas das artérias subclávias, com a realizaçäo de estudo angiográfico dos troncos supra-aórticos, especialmente naqueles pacientes com doença aterosclerótica difusa e/ou sinais de doença isquêmica cérebro-vascular e dos membros superiores, seja em pacientes que iräo submeter-se a cinecoronariografia e que potencialmente poderäo ter utilizadas as artérias mamárias para revascularizaçäo miocárdica, seja em pacientes submetidos a cirurgia de revascularizaçäo com o uso da artéria mamária e que voltam a apresentar angor e que no reestudo angiográfico mostram a anastomose patente
