RESUMO

Minimally invasive techniques for the treatment and diagnosis of kidney disease seek to preserve the greatest amount of parenchyma. Bleeding after these practices is rare, but must be treated quickly given its severity. Iatrogenic renal vascular injuries (IRVI) resulting from these procedures include active bleeding, arterial pseudoaneurysms, and arteriovenous fistulas. Renal artery embolization (RAE) is the main pillar in the treatment of this type of complications. OBJECTIVE: To assess the results of RAE for the treatment of IRVI and its impact on the renal function of patients. METHOD: Retrospective analysis of all patients who presented vascular complications after renal procedures and who were referred for management by RAE, between August 2012 and December 2020. RESULTS: 18 patients were included. 4 patients presented with pseudoaneurysm, 10 patients with active bleeding, and 1 patient with arteriovenous fistula; 2 patients had a combination of different IRVI; 1 patient did not present any findings at the time of renal angiography in dissonance with her computed tomography angiography. Technical and clinical success was achieved in all patients. One renal artery dissection was the only complication. No differences were found in serum creatinine (p = 0.51), urea (p = 0.37), hemoglobin (p = 0.26) and hematocrit (p = 0.24) after embolization. CONCLUSION: EAR is a safe and effective method for the treatment of IRVI, achieving a very high technical and clinical success rate with a low incidence of complications and without significant repercussions on the renal function of patients.

Las técnicas miniinvasivas para tratamiento y diagnóstico de la patología renal, buscan preservar la mayorcantidad de parénquima. Los sangrados posteriores a estasprácticas son de rara presentación, pero deben ser tratadosrápidamente dada su gravedad. Las lesiones iatrogénicasvasculares (LIV) renales derivadas de estos procedimientos incluyen sangrados activos, pseudoaneurismas arteriales y fistulas arteriovenosas. La embolización arterial renal (EAR) es el principal pilar en el tratamiento de este tipode complicaciones.Objetivo: Evaluar los resultados de la EAR para eltratamiento de LIV y su impacto en la función renal de lospacientes.Método: Análisis retrospectivo de todos los pacientesque presentaron complicaciones vasculares posteriores aprocedimientos renales y que fueron derivados para manejomediante EAR, entre agosto de 2012 y diciembre de 2020.Resultados: Se incluyeron 18 pacientes. 4 pacientesdebutaron con pseudoaneurisma, 10 pacientes con sangradoactivo y 1 paciente con fístula arteriovenosa; 2 pacientestenían combinación de diferentes LIV; 1 paciente no presento ningún hallazgo al momento de la angiografía renalen disonancia con su angio-TC. El éxito técnico y clínicose logró en todos los pacientes. Una disección de arteriarenal fue la única complicación. No se encontraron diferencias en la creatinina sérica (p = 0,51), urea (p = 0,37),hemoglobina (p = 0,26) y hematocrito (p = 0,24) despuésde la embolización.Conclusión: La EAR es un método segúro y eficazpara el tratamiento de LIV, alcanzando una tasa de éxitotécnico y clínico muy alta con una baja incidencia de complicaciones y sin repercusiones significativas sobre la función renal de los pacientes.
