Resumo
A dissecção espontânea da artéria renal é uma patologia rara que, na maioria dos casos, ocorre de forma idiopática. Em alguns casos, pode estar associada à presença de alterações arteriais prévias. Os sintomas geralmente são discretos e inespecíficos, dificultando o diagnóstico. Os autores relatam o caso de um paciente do sexo masculino, de 40 anos, com quadro de hipertensão arterial não controlada de início recente. Na investigação da etiologia da hipertensão arterial, o eco-Doppler de artérias renais revelou a presença de estenose (> 80%) no terço médio da artéria renal esquerda, e a angiografia evidenciou uma dissecção com dupla luz e redução do calibre do vaso. O paciente foi submetido a tratamento com implante de stent com evolução satisfatória.

Abstract
Spontaneous renal artery dissection is rare and most cases are considered idiopathic. Previous renal arterial disease may be present in some cases and clinical presentation is often non-specific. Here, the authors present a case of spontaneous renal artery dissection in a 40-year-old male patient with uncontrolled hypertension discovered during investigation of secondary hypertension. Duplex ultrasound initially showed 80% left renal artery stenosis which was shown to be a renal artery dissection during angiography. The patient was successfully managed by percutaneous placement of a renal artery stent.
