Doença renal ateroembólica: uma causa de insuficiência renal aguda pouco explorada

Abstract: ResumoO ateroembolismo é uma doença multisistêmica que afeta vários órgãos, entre os quais o rim, através da liberação de êmbolos de colesterol de uma placa aterosclerótica erosada, ocasionando obstrução vascular em diversos tecidos. A doença renal ateroembólica (DRAE), histologicamente representada por cristais de colesterol nas arteríolas do rim acompanhados de um infiltrado inflamatório perivascular, é causa de insuficiência renal aguda muitas vezes grave e prolongada, que ocorre semanas ou mesmo meses após… Show more

“…Glomeruli can have normal morphology in the initial stage, but ischemic retraction of podocyte foot processes, focal segmental glomerulosclerosis (FSGS), interstitial fibrosis, and tubular atrophy can be seen frequently due to ongoing ischemic injury in the later stages of the disease (Figure 1). Generally, immunofluorescence staining for immunoglobulin A (IgA), IgG, IgM, C3, C1q, fibrin, kappa, and lambda light chains are negative [31]. Renal biopsy has a sensitivity of about 75%.…”
