Abstract

Subclavian steal syndrome is a group of symptoms resulting from retrograde 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

A síndrome do roubo de subclávia é um grupo de sintomas decorrente de fluxo retrógrado na artéria vertebral, “roubando” o sangue da circulação posterior intracraniana e de outros territórios, causado por estenose ou oclusão da artéria subclávia proximal à origem da mesma artéria vertebral, ou mesmo do tronco braquiocefálico. Na maioria das vezes, trata-se de um achado incidental em pacientes com outras condições ou fatores de risco cerebrovasculares. Relatamos uma série de 29 pacientes com diagnóstico angiográfico, em que 7 receberam o tratamento (todos via endovascular), todos com sintomas diretamente relacionados a essa condição. Idade avançada, hipertensão arterial sistêmica, diabetes mellitus, tabagismo e acidente vascular cerebral foram comorbidades frequentemente relacionadas. Seis pacientes melhoraram totalmente após o procedimento e um permaneceu com vertigens.
