Recovery of renal function after bilateral renal vein thrombo sis episode as complication of membranous glomerulopa thy: case report / Recuperação da função renal após episódio de trombose de veia renal bilateral como complicação da glomerulopatia membranosa: relato de caso

ABSTRACT Renal vein thrombosis (RVT) is a complication often associated with nephrotic syndrome. It occurs due to a state of hypercoagulability common in the diseases that attend to this syndromic diagnosis. It should be suspected whenever there is nephrotic syndrome associated with sudden flank pain, hematuria and worsening of proteinuria. Bilateral RVT also presents with frequently oliguric renal dysfunction. This case reports a 33-year-old patient hospitalized for a nephrotic syndrome, with etiologic investigation suggestive of primary membranous glomerulopathy, which evolved with bilateral RVT associated with deterioration of renal function and need for renal replacement therapy. He promptly performed angiography with thrombectomy and thrombolysis, evolving with recovery of renal function in two weeks.

RESUMO A trombose de veia renal (TVR) é uma complicação muitas vezes associada à síndrome nefrótica. Ocorre devido a um estado de hipercoagulabilidade comum nas enfermidades que cursam com esse diagnóstico sindrômico. Deve ser suspeitada sempre que houver síndrome nefrótica associada à dor súbita em flanco, hematúria e piora da proteinúria. TVR bilateral cursa, ainda, com disfunção renal frequentemente oligúrica. Esse caso reporta um paciente de 33 anos internado por um quadro de síndrome nefrótica, com investigação etiológica sugestiva de glomerulopatia membranosa primária, que evoluiu com TVR bilateral associada à deterioração da função renal e necessidade de terapia substitutiva renal. Realizou, prontamente, angiografia com trombectomia e trombólise, evoluindo com recuperação da função renal em duas semanas.
