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.
