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.

Palavras-chave

artéria renal; dissecção; angioplastia.

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.
